With the popularity of the network and development of multimedia technology, the traditional information retrieval techniques do not meet the users?? demand. Recently, the content-based image retrieval has become the hot topic and the techniques of content-based image retrieval have been achieved great development. In this paper, the basic components of content-based image retrieval system are introduced...
P2P workflow systems meet the development trend of workflow systems. The running path optimization (the path with the minimum running time which consists of the services discovery time and the task execution time) in full-distribution (decentralized) environments has been a bottleneck restricting the performance of P2P workflow systems. Aiming at this problem, this paper proposes a innovative hybrid...
The new method of active fortify organizing a supervised area based on color and geometric feature is proposed in this paper. By the basis of color feature in the real supervised scene, in the first instance extracting several regions of interest (ROI) with noise, then matching with geometric shape by Fourier descriptors in the database, sequentially achieving automatic organizing a supervised area...
In this paper, we estimate the geometric characteristics, such as the relation of edges and the angle characteristics between edges, from single view. And we also use the prior knowledge about objects, such as the feature of edges and the geometry construction of objects, to construct the variable constraint based on the projection rules. In this paper, we transfer the problem of interpretation of...
According to the global and local features of Chinese manual alphabet images, Fourier descriptor and other multi-features is introduced for the vision-based multi-features classifier of Chinese sign language recognition. At first, extracting features of letter images is done, then classification method of SVMs for recognition is brought into use. Experimentation with 30 groups of the Chinese manual...
Relevance feedback (RF) proved an effect way to improve the precision and recall of 3D model retrieval. Unfortunately, through existing methods of RF, it is straightforward to find out whether a model is similar or not, but it is impossible to find out which local part is similar or not. The new partial method of RF proposed in this paper provides a good solution, in which not only the similar models...
In order to extract bottle boundary and pick out unqualified tube-type bottles which possibly have breaks and irregular shapes, a novel processing measure is taken based on wavelet transformation and mathematical morphology. Industrial bottle image contains noises so that traditional and theoretical image processing algorithms need to be improved. In addition, due to bottle inspection standard is...
The shape of red blood cell contributes more to clinical diagnosis with respect to blood diseases. In this paper, a compound classification algorithm for red blood cell was proposed, in which the depth map and surface curvature incorporated to deal with different kinds of cell shape. The original image was preprocessed to denoise and the individual 3-D shape of each cell was obtained with shape from...
In order to overcome classical wavelets' shortcoming in image processing problems, people developed many producing systems, which built up wavelet family. In this paper, the notion of AB-multiresolution analysis is generalized,and corresponding theory is developed. For an AB-multiresolution analysis associated with an expanding matrix, we deduce that there exists a singe scaling function in its reducing...
The establishment of the likelihood model of state observation with a strong robustness is one of the core issues in the study of moving hand tracking. This paper is dedicated to building a robust likelihood model of state observation, and do some study by using the method of gaining feature points from frame images of human hand. Firstly, based on physiological models and camera projection principle,...
The technique core of grain reserves automatical supervision and audit system which based on video is to identify the grain warehouse scene video, and accurately gets the sum of grain quantity. The key to identifying the quantity is the shape of package, and the key to identifying shape is processing and describing the boundary of package. Based on a lot of research and experiment on the edge detection...
