New Invariant Moments for Non-Uniformly Scaled Images 总被引:1,自引:0,他引:1
The usual regular moment functions are only invariant to image translation, rotation and uniform scaling. These moment invariants
are not invariant when an image is scaled non-uniformly in the x- and y-axes directions. This paper addresses this problem
by presenting a new technique to obtain moments that are invariant to non-uniform scaling. However, this technique produces
a set of features that are only invariant to translation and uniform/non-uniform scaling. To obtain invariance to rotation,
moments are calculated with respect to the x-y-axis of the image. To perform this, a neural network is used to estimate the
angle of rotation from the x-y-axis and the image is unrotated to the x-y-axis. Consequently, we are able to obtain features
that are invariant to translation, rotation and uniform/non-uniform scaling. The mathematical background behind the development
and invariance of the new moments are presented. The results of experimental studies using English alphabets and Arabic numerals
scaled uniformly/non-uniformly, rotated and translated are discussed to further verify the validity of the new moments. 相似文献

Distance measures and geometrical features are widely used to describe faces. Generally, they are extracted punctually from landmarks, namely anthropometric reference points. The aims are various, such as face recognition, facial expression recognition, face detection, study of changes in facial morphology due to growth, or dysmorphologies. Most of the time, landmarks were extracted with the help of an algorithm or manually located on the faces. Then, measures are computed or geometrical features are extracted to perform the scope of the study. This paper is intended as a survey collecting and explaining all these features, in order to provide a structured user database of the potential parameters and their characteristics. Firstly, facial soft-tissue landmarks are defined and contextualized; then the various measures are introduced and some results are given; lastly, the most important measures are compared to identify the best one for face recognition applications. 相似文献

Comparison of thinning algorithms on a parallel processor 总被引:1,自引:0,他引:1
CJ Hilditch 《Image and vision computing》1983,1(3):115-132
A number of parallel algorithms for thinning elongated shapes are contrasted and compared on a Clip 4 parallel processor. These algorithms all work in rectangular tessellation and they thin elongated objects to lines one pixel thick while retaining their connectivity. Existing algorithms for use on binary pictures are considered first and new algorithms are proposed which produce more satisfactory results, but are more expensive in terms of speed and space requirements. Two methods of extending these algorithms to grey pictures are then considered. In one method, binary algorithms are used but are directed by the grey pixels; in the other the binary algorithms are generalized to the grey case. Both methods result in arcs which are not wholly determined by the original boundary of the object but lie along darker ridges. The former is faster and produces results which are easier to interpret, but the results from the latter contain more information. 相似文献

基于图像的实时漫游 总被引:3,自引:0,他引:3
提出了一个点和多边形模型混合的场景表达方式,从而实现了对复杂场景的视点不受限制的实时漫游.它从多幅带深度的参考图像出发,在预处理阶段区别对待场景中平面物体和曲面物体在参考图像中的对应像素.对于在参考图像所占区域较大的空间平面,用传统的多边形模型方式对其进行表达,试图恢复出其平面方程,然后通过采样密度比较和重采样过程,将该空间平面在所有参考图像中的出现合并成一个均匀采样的纹理图像;而对于空间曲面或在参考图像中所占面积较小的平面,使用点的形式对其进行表达,通过采样密度的比较去掉冗余的点,将保留下来的点按其空间位置进行聚类.同时,对于场景中那些不被所有参考图像所拍摄到而在漫游过程中可能形成空洞的部分,提出一个空洞预填补技术,在预处理阶段即对这类空洞进行填补,从而大大减少了漫游阶段出现空洞的几率.在漫游阶段则使用纹理映射和点Warping的方式进行绘制,以充分利用图形硬件的加速功能. 相似文献

Knowledge-support systems 总被引:1,自引:0,他引:1
Brian R. Gaines 《Knowledge》1990,3(4):192-203
The social role of information technology is analysed in order to provide a framework for reasonable requirements for knowledge support systems. The many different scientific and engineering communities targeted on the development of specific knowledge support technologies are noted, and the problems of integrating developments from different communities are highlighted. The architectures of current integrated knowledge support systems are analysed within the social framework and the strengths and weaknesses of current modules are evaluated. Major system developments in recent years are used to exemplify the analysis, and expected directions for future development are outlined. The framework, analyses and examples are used to define a structured requirements specification for future research and development related to knowledge support systems. 相似文献
