| Abstract(in English) | We recognize a region of almost rectilinear high intensity mound as a kind of lines. There are few methods to detect such "line" as compared with edge detection methods. In this work, we propose a filter to detect, and/or enhance curvilinear convex regions. They are represented as line-convergence vector fields and the filter output is define as the average of line-convergence degree in the region of support, of the proposed filter, which is adapted to the distribution of gradient vector field. The filter output is a function of only gradient vector orientations and it is free from absolute intensity and relative contrast variations. Practical computation procedure is also given. in which GAWHT (Gradient-Angle-Weighted Hough Transform) is adopted. Experiments using artificial image and real medical image, are shown, whose results show the effectiveness of the proposed filter. |
