        摘要：In this paper， a method about Quasar spectrum recognition is proposed. Firstly, on the signal with extreme points as its features, we introduce two important properties of multiscale morphological dilation (erosion). One is the monotone rate which is the basis of an adaptive scalar selection mechanism; the other is the monotone property which can be used to localize the features accurately by “Coarse to Fine”strategy. According to these properties, the spectrum is filtered by multiscale dilation and its features are recovered. Secondly， elastic matching is proposed to featur ever if ication and its physical meaning is pointed out. In fact, this method can be applied to other fields effectively.

        摘要：A graph-based algorithm for generating the Delaunay triangulation of aplanar point set is presented in this paper. The first step is to calculate the Euclidean Minimum Spanning Tree (EM ST) of the given points. The EM ST is then augumented to triangle mesh. Finally the Delaunay Triangulation of the given points is obtained by local tranformation acording to Max-M in angle criteria. The concepts and properties of Vorono i diagram of a planar point set are slso discussed in the paper.

      • State of the art and Future the development of stereo vision

        Vol. 2, Issue 1, Pages: 12(1997) DOI: 10.11834/jig.19970116
        摘要：Stereo vision,an important branch of computer vision,is one of the wideest research area in Computer Vision.In prerious decades,a 1ot of characteristic approaches and theories were progressively Proposed In this area In this Paper,the State of fhe art of Stereo vision is expounded systematically,and the advantages and disadvantages of some important appreaches are discussed,With an emphasis on stereo matching atching,the key prob1em in stereo vision expounded Comprehensively.Findlly,the existing problems and future development in stereo vision are discussed.

        摘要：The triple correlation of 2D image is a complete representation of images. It has the properties of translation invariance and insensitivity to AGN. In this paper, according to the similarity among the vector triangles formed by two indepentent vectors of triple correlation function, the distributions of these two vectors are discussed, so that the triple correlation function based on the triangle form is introduced. The translation rotation scale invariant representation is established by logarithmic mapping of the scaling factor, and FFT transforming of this function.The simulation experiment illustrates the translation rotation scale invariance of invariant representation.

In this paper, according to the similarity among the vector triangles formed by two indepentent vectors of triple correlation function, the dist ributions of these two vectors are discussed, so that the triple correlation function based on the triangle form is introduced. The translation-rotation-scale invariant representation is established by logarithmic mapping of the scaling factor, and FFT transforming of this function. The simulation experiment illustrates the translation-rotation-scale invariance of invariant representation.

        摘要：This paper discusses the method of getting bodys 3D space data, a Jing luo (meridians and collaterals) data model based on homogeneous coordinate transform is purposed,which not only solve the problems of animation demonstration and transparent reiteration of Jingluo and acupoints, but also lay the foundation for advanced research on Jingluo by mathematics or making overall observaton. The method of displaying Targa image and FLI animation under Windows environment is purposed after analyzing their formats.
