The author presents a novel feature of three-dimensional (3D) patterns invariant to shift and rotation based on the third-order correlation. The invariant feature, the table of the triple product of similar triangles, represents the amount of the apexes of similar triangles in 3D image data. Computer simulation shows that three kinds of 3D lattice point patterns are well recognized under random shift and rotation by using the invariant feature.

Information fusion by combining multiple sensor data and classifiers has received considerable interest in recent years. It is believed to be an effective way to design patternrecognition systems with high recognition accuracy, reliability, and robustness, to deal with the variance-bias dilemma, to handle different sensor of feature types and scales, and to maximally exploit the discriminant power of individual features and classifiers (experts). This paper provides a brief survey and a taxonomy of various schemes, which are characterized by their (i) architecture, (ii) selection and training of individual classifiers,. and (iii) combiner's characteristics. Recent work on theoretical analysis on combination schemes is also briefly summarized.

New approaches to the problem of matching method for dissimilar handwritten character images are presented in this paper. One of them is for the offline recognition of dissimilar two-stroke digits which are difficult to discriminate. Several measures are taken to obtain proper division and description of the two strokes to further discrimination. In the recognition stage we combined syntactic analysis with statistical calculation. The other approach is for verifying offline handwritten Chinese signatures. Local connection properties are fully employed and the weighted distances are calculated on the whole signature image. Experiments results show that using the proposed matching methods increased the recognition rate and improved the reliability of our OCR system and is also helpful for verification of handwritten Chinese signatures.

Wavelet, asa brand new tool in signal processing, has got broad recognition. Using wavelet transform, we can get octave divided frequency band with specific orientation which combines well with the properties of Human Visual System (HVS). In this paper, we discuss the classified vector quantization (CVQ) method for multiresolution represented image.

A purely automated technique is proposed for detection of "grain" objects on pseudohomogeneous background and statistical estimation of their geometrical parameters. The objects are distinguished from background by average brightness and have some characteristic shape. Combination of discriminant and structural approaches to patternrecognition are involved. Original boundary tracking algorithm is used at segmentation stage.

The image registration is one of the key points in the integrative analysis of image data. In this paper, a full-automatic method for registration between SPOT and TN image is described. The results of the experiment show that the method is much better than traditional manual approach both in the efficiency and the accuracy.

In this paper, our purposes ale image compression code by wavelet transformation, and develop a novel encoding algorithm structure of DPCM/WT on the basis of the DPCM/DCT. We have proposed a new encoding algorithm structure of DPCM/WT based on object driving and data flow driving. the novel algorithm in property is superior to DPCM/DCT in compression ratio, fidelity and real time processing.
