一种新的血管造影图像Hessian矩阵增强算法
A Novel Hessian Matrix Enhancement Algorithm for Angiography Images
摘要
Abstract
A novel Hessian matrix algorithm is presented to enhance angiography images considering their noise and non-uniform illumination. The algorithm is performed in four steps:decimation-free directional filter bank decomposing, homomorphic filtering, Hessian eigenvalues matrix, and directional image reconstruction. Experimental results show that the proposed'algorithm can detect filamentous image structures continuously,and has great advantages of both noise insensitioity and image visual quality,in comparison to the traditional Hessian algorithms.关键词
