there is a physiological reason, backed up by the theory of visual attention in living organisms, why animals look into each others’ eyes. this is to illustrate the main two properties in which recognizing of faces i...

this article describes an artificial vision system for the quality control of cherries. It allows to obtain three types of information describing the fruit : the color as indicator of the ripeness, the presence of defects such as cracking and lastly the size. the sorting of cherries conditioned by all these criteria is carried out at a high cadence (twenty cherries per second). Optimized algorithms of image processing axe then necessary. We present in this paper the architecture of the developed system and we show the efficiency through experimental results.
In this work we propose a new descriptor of the local texture in gray-level images, named Simplified Texture Unit (STU). this descriptor is a version, with a smaller computational cost as much in its obtaining as in i...

Design of experiments has already been used for several years in different domains. It is often ignored in image processing. In this article, we would Re to show that it has it place in this area where it is common to have parameters to be adjusted according to the images to be processed and which should remain valid for a family of images of the same type. these parameters are often numerous and they frequently interfere with each others. the use of an active contour requires several parameters rather delicate to be adjusted. the experimental research methodology allows, the factors to be considered to be listed and then, from these, the identification of those which are the most influential, in order to optimize them.

A new method is proposed for automatic recognition of brain tumors from MRI. the prevailing convention in the literature has been for humans to perform the recognition component of tumor segmentation, while computers automatically compute boundary delineation. this concept manifests as clinical tools where the user is required to select seed points or draw initial contours. the goal of this paper is to experiment with automating the recognition component of the image segmentation process. the main idea is to compute a map of the probability of pathology, and then segment this map instead of the original input intensity image. Alternatively, the map could be used as a feature channel in an existing tumor segmentation method. We compute our map by performing nearest neighbor pattern matching modified with our novel method of "diagonalization". Results are presented for a publicly available data set of brain tumors.
A class of enhancement techniques is proposed for images in arbitrary dimension D. they are free from either space/frequency (scale) or grey references. there are two subclasses. One subclass is the chain: {Negative L...
