This paper proposed a same-name feature point registration method based on feature contour. By analyzing the map of multi-beam water depth false-gray image and side-scan sonar image, and adopting CANNY operator to extract contour line. Then select the turning points which cater the constraints as the feature points, and deal the feature points with quadratic polynomial algorithm to obtain the deformation...
In this paper, the radial basis vector (RBV) is proposed to describe the descriptor set of an image. And the shared nearest neighbor clustering kernel (SNNCK) technique is proposed to match RBV pairs. SNNCK is based on the charge attractive model, which will make the unequal-dimensional data sets clustering naturally. Thus, this novel algorithm is able to match the unequal-dimensional data sets when...
Recently, the development of satellite cloud image processing technology has become very quick; the research aspects concentrate on judge the cloud type and classify the cloud mainly. These image processing methods relate to the subject category like image processing and pattern recognition etc; it has become one of the fields of most quickly development in the research of satellite image processing...
