Relaxation matching is one of the most relevant methods for image matching. The original relaxation matching technique using point patterns is sensitive to distortions such as missing and spurious points and random errors. In this paper, under the condition that the number of spurious points is known, we present an improved point pattern relaxation matching technique which can get better performance than the original one. Experimental results with simulated images are given.

This paper presents a new method for locating eye accurately. In the first stage, the proposed method finds the coarse eye region from image using genetic algorithm based on the edge information and intensity distribution information. In the second stage, ellipse detection is employed to extract the boundary of the iris. The experimental results have shown that the proposed method can locate eyes accurately from the input image with complex background.

A new algorithm for image partition using irregular region in fractal image compression is purposed in this paper, which greatly increases the compression ratios achieved over traditional block-based partition. Also, due to the large search space involved(transformations and match), Similar Extension algorithms which are described are used to construct the irregular region transformations, and results for Similar Extension algorithms are shown. The results show that the algorithm of irregular region achieves almost double the compression ratio of simple block-based system at a similar decompressed image quality.

Searching object's centroid fast and correctly is the important part in patternrecognition and object tracking. So it is crucial to search centroid fast and correctly. Song suggests a method of searching centroid with "City Block Distance" template and difference image. But the method of Song has two disadvantages, so an improved fast algorithm for searching centroid of object in binary image is proposed in this paper. Searching time and area are reduced greatly by the improved algorithm. It is turned out that the improved method is faster than not improved one by the experiment.

In this paper we obtain higher pattern analysis accuracy through the fusion of uncorrelated discriminant vectors, correlated discriminant vectors and kernelized discriminant vectors by some fusion theory and technology which is carried out by some estimation method of multi-feature. Based on some different features such as linear and non-linear features, correlated and uncorrelated features, one estimation method of multi-feature is proposed to fuse these different vectors. Finally experiments on human face recognition are carried out and prove our methods to be available.

This paper presents a novel digital image watermarking scheme that is invariant to rotation, scaling, and translation (RST). We embed watermark in the log-polar mapping,,, of the Fourier magnitude spectrum. of m original image, and use the phase information of the original image to rectify the watermark positions. The scheme avoids computing inverse log-polar mapping (ILPM) to preserve image quality. bind avoid exhaustive search to save computation time and reduce false detection rate.

The linear trajectory is one of major performance for industrial robot. A vision-based robots' linear trajectory measure system is introduced in this paper using a structure light and a special measure track. The three inflexions of the optical strip imaging at the V shape truck are used to compute the pose between the sensor frame and the track frame, then the linear trajectory of robot can be computed. The emphasis of this paper is the imageprocessing. At this paper. the process of the imageprocessing method for this system will be described at first. then the key methods include image segmentation and line fitting will be discussed, at last the experiment results will be given.
