In this paper, illumination-affine invariant methods are presented based on affine moment normalization techniques, Zernike moments, and multiband correlation functions. The methods are suitable for the illumination invariant recognition of 3D color texture. Complex valued moments (i.e., Zernike moments) and affine moment normalization are used in the derivation of illumination affine invariants where the real valued affine moment invariants fail to provide affine invariants that are independent of illumination changes. Three different moment normalization methods have been used, two of which are based on affine moment normalization technique and the third is based on reducing the affine transformation to a Euclidian transform. It is shown that for a change of illumination and orientation, the affinely normalized Zernike moment matrices are related by a linear transform. Experimental results are obtained in two tests: the first is used with textures of outdoor scenes while the second is performed on the well-known CURET texture database. Both tests show high recognition efficiency of the proposed recognition methods. 相似文献

A fast method for computing Hu’s image moment invariants is described. The invariants are found by approximation using generalized
moments computed in a sliding window by a parallel recursive algorithm. The proposed method is shown to be computationally
more efficient than direct computation.

Application of nonlinear methods of multivariate regression approximation (neural networks, functions linear in fitting parameters,
and hierarchical approximation) is considered to problems of image filtering based on a priori information in the form of
matched pairs of images (“ideal” and “degraded”). The methods are compared with regard to their efficiency.

High performance Mandarin digit recognition(MDR)is much more difficult to achieve than its English counterpart,especially on inexpensive hardware implementation.In this paper,a new ,Multi-Layer Perceptrons(MLP)based postprocessor,an a posteriori probability estimator is presented and used for the rejection model of the speaker independent Mandarin digit recognition system based on hidden Markov model(HMM).Poor utterances,which are recognized by HMMs but have low a posteriori probability,will be rejected.After rejecting about 4.9% of the tested utteraces,the MLP rejection model can boost the digit recognition accuracy from 97.1%to 99.6%,The performance is better than those rejection models based on linear discrimiantion,likelihood ratio or anti-digit. 相似文献

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.

Color is one of the most important features in digital images. The representation of color in digital form with a three-component
image (RGB) is not very accurate, hence the use of a multiple-component spectral image is justified. At the moment, acquiring
a spectral image is not as easy and as fast as acquiring a conventional three-component image. One answer to this problem
is to use a regular digital RGB camera and estimate its RGB image into a spectral image by the Wiener estimation method, which is based on the use of a priori knowledge. In this paper, the Wiener estimation method is used to estimate the spectra of icons. The experimental results of the spectral estimation are presented.

Singularity analysis in an important subject of the geometric constraint satisfaction problem.In this paper,three kinds of singularities are described and corresponding identifcation methods are presented for both under0constrained systems and over-constrained systems,Another special but common singularity for under-constrained geometric systems,pseudo-singularity,is analyzed.Pseudo-singularity is caused by a variety of constraint mathching of under-constrained systems and can be removed by improving constraint distribution.To avoid pseudo-singularity and decide redundant constraints adaptively,a differentiaiton algorithm is proposed in the paper.Its corrctness and effciency have been validated through its practical applications in a 2D/3D geometric constraint solver CBA. 相似文献

Zernike moments have been extensively used and have received much research attention in a number of fields: object recognition, image reconstruction, image segmentation, edge detection and biomedical imaging. However, computation of these moments is time consuming. Thus, we present a fast computation technique to calculate exact Zernike moments by using cascaded digital filters. The novelty of the method proposed in this paper lies in the computation of exact geometric moments directly from digital filter outputs, without the need to first compute geometric moments. The mathematical relationship between digital filter outputs and exact geometric moments is derived and then they are used in the formulation of exact Zernike moments. A comparison of the speed of performance of the proposed algorithm with other state-of-the-art alternatives shows that the proposed algorithm betters current computation time and uses less memory. 相似文献

With the developemnt of network applications,routers must support such functions as firewalls,provision of QoS,traffic billing,etc.All these functions need the classification of IP packets,according to how different the packetes are processd subsequently,which is determined.In this article,a novle IP classification algorithm is proposed based on the Grid of Tries algorithm.The new algorithm not only eliminates original limitations in th case of multiple fields but also shows better performance in regard to both and space.It has better overall performance than many other algorithms. 相似文献

The paper considers one of the stages of creating and reneqing digital maps, i.e., georeferencing and calibrating cartographic
representations (scanned topographic drawings). It is proposed to use the standards accepted in Russia for paper maps to search
for intersections in the coordinate lines using known physical coordinates. An algorithmic system and software consisting
of the following stages have been developed: search for interior and exterior margins of the topographic drawing, search for
intersections of coordinate lines, verification of detected control points, and geometric transformation. The use of this
method allows one to exclude hand labor by operators, which saves 10–20 min per map board.

Traditional network management approach involves the management of each vendor‘s equipment and networkd segment in isolation through its own proprietary element management system.It is necessary to set up a new network management architecture that calls for operation consolidation across vendor and technology boundaries.In this paper,an architerctural model for Intelligent Network Management(INM)is presented.The INM system includes a manager system,which controls all subsystems and coordinates different management tasks;an expert system,which is responsible for handling particularly difficult problems,and intelligent agents,which bring the management closer to applications and user requirements by spreading intellignet agents through network segments or domain.In the expert system model proposed,especially an intellignet fault management system is given.The architectural model is to build the INM system to meet the need of managing modern network systems. 相似文献

The automatic segmentation of news items is a key for implementing the automatic cataloging system of news video.This paper presents an approach which manages audio and video feature infomation to automatically segment news items.The integration of audio and visual analyses can overcome the weakness of the approach using only image analysis techniques.It makes the approach more adaptable to various situations of news items.The proposed approach detects silence segments in accompanying audio,and integrates them with shot segmentation results,as ewll as anchor shot detection results,to determine the boundaries among news items,Expeimental results show that the integration of audio and video features is an effective approach to solving the problem of automatic segmentation of news items. 相似文献
