The 3D data can be extracted by measuring healthy hip joint, which is the basis of making proper artificial hip conform to right physiological characteristics. In this paper, firstly, we use adaptive windows directed by neighbouring CT slices for reducing ranges of searching. Secondly, a method based on 2D contour characteristic points matching in multilayer is proposed to effectively correct contours...
To improve the real-time and robustness of the dynamic visual recognition, this paper proposed a new mechanism and implementation techniques for evolutionary recognition, which is a perceptive--expressive interaction imitating the oil painting process. This mechanism can transform the oil painting process of continual observation, multi-level description, and repeated confirmation into the gradual...
To improve the correctness and real-time performance in the process of image matching, this paper proposed a fast matching algorithm based on image K-gray-degree clustering. Given a template with irregular shape, this algorithm divides the image into certain size blocks called R_block, and calculates their mean gray value, then clusters original templates to K-degree templates according to gray distribution...
