It is a frequently encountered problem to calculate the area of target region in image processing. Based on an improved algorithm of contour extracting, a method for calculating the area of target region was advanced. First, the contour is extracted from the binary image, while note the location and type information of the contour points. Next, the area of target region is calculated by weighting...
According to the problem of graph cuts matching algorithm that lots of false matches appears in weak texture area, an improved graph cuts matching algorithm for dense matching is proposed in this paper. First, corner point detection and matching are made between stereo image pairs, and false matches are eliminated by relaxation algorithm and LMeds algorithm. Secondly, triangulate partitioning of discrete...
In this work, the notion of a class of vector-valued bivariate wavelet packets associated with an arbitrary integer-valued dilation matrix is developed. A new method for constructing vector-valued bivariate wavelet packets is proposed. Their characteristics is researched by means of operator theory, time-frequency analysis method and matrix theory. Three orthogonality formulas regarding the wavelet...
