Edge Information Extraction Algorithm of CT Cerebrovascular Medical Image Based on Imaginary Part of Gabor Filter
Qin Ran · Journal of Tianjin University Science and Technology · 2007
The imaginary part of Gabor filter is not used alone in image processing though the real part of it is wildly used in this field.To insure the quality of 3D image reconstruction and the edge information extraction,the characters of the Sobel operator and the imaginary part of Gabor filter are analyzed.The imaginary part of Gabor filter is introduced into the edge information extraction of CT cerebrovascular medical image.The Gabor filter algorithm is improved under certain conditions,and the complexity is reduced from O(n2) to O(n).
