This paper shows that the efficiency bound for communication equilibria identified by Goltsman, Hörner, Pavlov and Squintani [15] in the leading example of the CrawfordSobel model can be obtained with strategy-correlated equilibria, thus preserving privacy vis-à-vis the mediator. More generally, all equilibrium outcomes of the -noise model of Blume, Board and Kawamura [4], including outcomes wi...

This paper presents a lifting wavelet based edge detection algorithm for NaXi Pictographs, effectively reducing noises while improving the precision, which makes up the drawbacks of traditional edge detection. It is proved by emulation that compared with Laplace operator, Sobel operator, Canny operator, and multi-scale wavelet edge detection algorithm, this algorithm has better detection effect.

The interaction of quadriplegic people with technology has been minimal in most cases and applications, which has generated a wealth of needs that affect the comfort and well being of the same. The purpose of this project is to design and implement a prototype to perform a scan and parameterization of the retina by image processing software to handle a given platform based on Windows.The operat...

Tracking of moving objects that is called video tracking is used for measuring motion parameters and obtaining a visual record of the moving objects, it is an important area of application in image processing. In general there are two different approaches to obtain object tracking: the first is Recognition-based Tracking, and the second is the Motion-based Tracking. Video tracking system raises...

Image Enhancement is one of the first steps in Image processing. It is a cosmetic procedure, i.e. it does not add any extra information to the original image. It merely improves the subjective quality of the images by working with the existing data and is used for improving the interpretability or perception of information in images for human viewers. In this project, hybrid approach and Log-So...

Edge detection is an important task in image processing. There are a lot of approaches in this area: Sobel, Canny operators and others. One of the perspective techniques in image processing is the use of fuzzy logic and fuzzy sets theory. They allow us to increase processing quality by representing information in its fuzzy form. Most of the existing fuzzy image processing methods switch to fuzz...
