چکیده
The logarithmic model offers new tools for image processing. An efficient method for image enhancement is to use an affine transformation with the logarithmic operations: addition and scalar multiplication. We define some criteria for automatically determining the parameters of the processing and this is done via mean and variance computed by logarithmic operations. keywords : logarithmic image processing, image enhancement, affine transforms.

This paper describes an approach to real-time detecting static pointing armpostures which can be used to send position instructions to a mobile robot. This takes place by analyzing the color image and utilizing the range image of the scene obtained by a stereo vision system. First the algorithm locates the person’s face and afterwards the arm-postures are recognized. The start as well as the en...

An information theoretic approach is used to hide a visually meaningful and recognizable two level watermark symbol in the spatial domain. Watermark insertion regions are selected using both Shannon’s entropy measure as well as non-Shannonian entropy for image data. Experimental results confirm the robustness of the proposed scheme against several kinds of attacks, such as lossy compression, fi...

In the article we present the process of scene model fusion. It consists of several iterations performed separately for each viewpoint. In the approach we find a weak subgraph isomorphism from a graph of a new observation to a model graph. We combine a modified Ullman algorithm for subgraph matching with Procrustes methods of 3D shape analysis. Such solutions make it possible to quickly and acc...

We propose a biologically motivated computational step, called surround inhibition, which improves the performance of contour detectors. The mechanism of surround inhibition is exhibited by the majority of the orientation selective neurons in the primary visual cortex of macaque monkeys and has been demonstrated to influence the visual perception of man as well. We illustrate the principle and ...
