The gray-level absolute central moment of the first order provides ridges at gray-level discontinuities as well as a conventional
gradient of Gaussian (GoG). A mass center b of the gray-level variability can also be associated to the first absolute central moment. When given a starting point p, vector b indicates the path which joins p to the nearest gray-level discontinuity as well as the gradient of the GoG magnitude. However, when the right configuration
of the operator is chosen, vector b indicates a point which is closer to the discontinuity than p, regardless of the distance between p and the discontinuity. Therefore, when using vector b, gray-level discontinuities can be located with an iterative approach. In this paper, the edge detection properties of the
first absolute central moment are compared with those of the GoG.

Ancient documents are usually degraded by the presence of strong background artifacts. These are often caused by the so-called
bleed-through effect, a pattern that interferes with the main text due to seeping of ink from the reverse side. A similar
effect, called show-through and due to the nonperfect opacity of the paper, may appear in scans of even modern, well-preserved
documents. These degradations must be removed to improve human or automatic readability. For this purpose, when a color scan
of the document is available, we have shown that a simplified linear pattern overlapping model allows us to use very fast
blind source separation techniques. This approach, however, cannot be applied to grayscale scans. This is a serious limitation,
since many collections in our libraries and archives are now only available as grayscale scans or microfilms. We propose here
a new model for bleed-through in grayscale document images, based on the availability of the recto and verso pages, and show
that blind source separation can be successfully applied in this case too. Some experiments with real-ancient documents arepresented
and described.

Computer vision tasks such as registration, modeling and object recognition, are becoming increasingly useful in industry.
Each of these applications employs correspondence algorithms to compute accurate mappings between partially overlapping surfaces.
In industry, it is essential to select an appropriate correspondence algorithm for a given surface matching task. A correspondence
framework has recently been proposed to assist in the selection and creation of correspondence algorithms for these tasks.
This paper demonstrates how to use the correspondence framework to create a new surface matching algorithm, which uses stages
of an existing model matching algorithm. The efficiency with which the new algorithm is created using the correspondence frame
work is emphasized. In addition, results show that the new algorithm is both robust and efficient.

In this paper we present a system for statistical object classification and localization that applies a simplified image acquisition
process for the learning phase. Instead of using complex setups to take training images in known poses, which is very time-consuming
and not possible for some objects, we use a handheld camera. The pose parameters of objects in all training frames that are
necessary for creating the object models are determined using a structure-from-motion algorithm. The local feature vectors
we use are derived from wavelet multiresolution analysis. We model the object area as a function of 3D transformations and
introduce a background model. Experiments made on a real data set taken with a handheld camera with more than 2500 images
show that it is possible to obtain good classification and localization rates using this fast image acquisition method.

Algorithmic and architectural design for real-time and power-efficient Retinex image/video processing 总被引:1,自引:1,他引:0
Sergio Saponara Luca Fanucci Stefano Marsi Giovanni Ramponi 《Journal of Real-Time Image Processing》2007,1(4):267-283
This paper presents novel algorithmic and architectural solutions for real-time and power-efficient enhancement of images
and video sequences. A programmable class of Retinex-like filters, based on the separation of the illumination and reflectance
components, is proposed. The dynamic range of the input image is controlled by applying a suitable non-linear function to
the illumination, while the details are enhanced by processing the reflectance. An innovative spatially recursive rational
filter is used to estimate the illumination. Moreover, to improve the visual quality results of two-branch Retinex operators
when applied to videos, a novel three-branch technique is proposed which exploits both spatial and temporal filtering. Real-time
implementation is obtained by designing an Application Specific Instruction-set Processor (ASIP). Optimizations are addressed
at algorithmic and architectural levels. The former involves arithmetic accuracy definition and linearization of non-linear
operators; the latter includes customized instruction set, dedicated memory structure, adapted pipeline, bypasses, custom
address generator, and special looping structures. The ASIP is synthesized in standard-cells CMOS technology and its performances
are compared to known Digital signal processor (DSP) implementations of real-time Retinex filters. As a result of the comparison,
the proposed algorithmic/architectural design outperforms state-of-art Retinex-like operators achieving the best trade-off
between power consumption, flexibility, and visual quality.

In this article, the developed program and research system for recognizing individuals based on photos of faces on documents
is described. The requirements for the system made at the development stage are determined. The most important of these requirements
is the possibility of carrying out the investigations of various algorithms with the purpose of the comparing their efficiency,
determining their optimum parameters, and selecting the best system of signs. The composition and destination of the main
components of the program and research system for recognizing individuals are presented. The main feature of implementation
is the use of processing scenarios in the system performed by an interpreter and the presence of an expanded set of the elemental
processing functions. This solution results in the rapid development and variation of various algorithms of image processing,
formation of signs, and classification.

To meet both flexibility and performance requirements, particularly when implementing high-end real-time image/video processing
algorithms, the paper proposes to combine the application specific instruction-set processor (ASIP) paradigm with the reconfigurable
hardware one. As case studies, the design of partially reconfigurable ASIP (r-ASIP) architectures is presented for two classes
of algorithms with widespread diffusion in image/video processing: motion estimation and retinex filtering. Design optimizations
are addressed at both algorithmic and architectural levels. Special processor concepts used to trade-off performance versus
flexibility and to enable new features of post-fabrication configurability are shown. Silicon implementation results are compared
to known ASIC, DSP or reconfigurable designs; the proposed r-ASIPs stand for their better performance–flexibility figures
in the respective algorithmic class.

The problem of searching for and recognizing fragments of images that correspond to one of a wide variety of template is considered.
The method of the fast correlation of a wide selection of trinary template, which successfully resolves this problem, is suggested.
The use of this method in two problems of image analysis is shown, namely, the search for position of eyes in documental photographs
of faces and the recognition of computer-readable lines in scanned images of documents.

QoS Management Through Adaptive Reservations 总被引:5,自引:2,他引:3
Reservation based (RB) scheduling is a class of scheduling algorithms that is well-suited for a large class of soft real-time applications. They are based on a bandwidth abstraction, meaning that a task is given the illusion of executing on a dedicated slower processor. In this context, a crucial design issue is deciding the bandwidth that each task should receive. The point we advocate is that, in presence of large fluctuations on the computation requirements of the tasks, it can be a beneficial choice to dynamically adapt the bandwidth based on QoS measurements and on the subsequent application of feedback control (adaptive reservations).In this paper, we present two novel contributions to this research area. First, we propose three new control algorithms inspired to the ideas of stochastic control. Second, we present a flexible and modular software architecture for adaptive reservations. An important feature of this architecture is that it is realised by means of a minimally invasive set of modifications to the Linux kernel.This work has been partially supported by the European OCERA IST-2001-35102 and RECSYS IST-2001-32515 projects.Luca Abeni is a Ph.D. in Computer Engineering at the Scuola Superiore SantAnna of Pisa (Italy).

In this paper we propose a novel approach for facial feature detection in color image sequences using Haar-like classifiers.
The feature extraction is initialized without manual input and has the capability to fulfill the real time requirement. For
facial expression recognition, we use geometrical measurement and simple texture analysis in detecting facial regions based
on the prior detected facial feature points. For expression classification we used a three layer feed forward artificial neural
network. The efficiency of the suggested approach is demonstrated under real world conditions.

In the recent past, several researchers have shown that important variables in relearning motor skills and in changing the
underlying neural architecture after stroke are the quantity, duration, content, and intensity of training sessions. Unfortunately,
when traditional therapy is provided in a hospital or rehabilitation center, the patient is usually seen for few hours a week.
Robot-mediated therapies could improve this situation but even if interesting results have been achieved by several groups,
the use of robot-mediated therapy has not become very common in clinical practice. This is due to many different reasons (e.g.,
the “technophobia” of some clinicians, the need for more extensive clinical trials) but one of the more important is the cost
and the complexity of these devices which make them difficult to be purchased and used in all the clinical centers.
The aim of this work was to verify the possibility of improving motor recovery of hemiparetic subjects by using a simple mechatronic
system. To achieve this goal, our system (named “MEchatronic system for MOtor recovery after Stroke” (MEMOS)) has been designed
with the aim of using mainly “off-the-shelf products” with only few parts simply manufactured with standard technology, when
commercial parts were not available. Moreover, the prototype has been developed taking into account the requirements related
to the clinical applicability such as robustness and safety.
The MEMOSsystem has been used during clinical trials with subjects affected by chronic hemiparesis (<6 months from the cerebrovascular
accident). The results obtained during these experiments seem to showthat notwithstanding the simple mechatronic structure
characterizing theMEMOSsystem, it is able to help chronic hemiparetics to reduce their level of impairment.
Further clinical experiments with acute and chronic subjects will be carried out in order to confirm these preliminary findings.
Moreover, experiments for tele-rehabilitation of patients will be also carried out.

Active reconstruction of 3D surfaces deals with the control of camer a viewpoints to minimize error and uncertainty in the
reconstructed shape of an object. In this paper we develop a mathematical relationship between the setup and focal lengths
of a stereo camera system and the corresponding error in 3D reconstruction of a given surface. We explicitly model the noise
in the image plane, which can be interpreted as pixel noise or as uncertainty in the localization of corresponding point features.
The results can be used to plan sensor positioning, e.g., using information theoretic concepts for optimal sensor data selection.

This paper presents the iris recognition system for biometric personal identification using neural network. Personal identification
consists of localization of the iris region and generation of a data set of iris images followed by iris pattern recognition.
In this paper, a fast algorithm is proposed for the localization of the inner and outer boundaries of the iris region. Located
iris is extracted from an eye image, and, after normalization and enhancement, it is represented by a data set. Using this
data set a Neural Network (NN) is used for the classification of iris patterns. The adaptive learning strategy is applied
for training of the NN. The results of simulations illustrate the effectiveness of the neural system in personal identification.

A method for controlling the maximum restoration error in image compression is proposed that can be used in combination with
the arbitrary methods of compression. The method has been studied for the case of its application together with the standard
compression method JPEG. The results have shown that, at equal coefficients of compression, the proposed method substantially
reduces the maximum error of image restoration.
