基于融合的显微图像Gabor边缘提取算法

不同参数Gabor滤波器都具有各自的频率选择和方向选择特性,图像中纹理基元可以利用多个方向和中心频率Gabor滤波器组提取出来的频谱值来表示.据此提出一种适应于显微图像的Gabor滤波边缘检测算法.使用特定不同方向Gabor滤波边缘提取算子对图像进行边缘信息提取,获得不同方向上边缘特征信息,对其进行分析和融合提取图像边缘.运用该方法时所获不同方向的图像边缘进行自适应融合,获得的图像边缘较理想,模糊的边缘得到增强,并有效地消除了噪声.实验结果表明,该算法对显微图像处理有效,检测到的边缘清晰.

Gabor filtering algorithm for micrograph edge detection based on fusion method

The performances of frequency and orientation selection are speculated by Gabor filters in different parameters.Texture elements in an image can be represented by frequency values exacted from a set of Gabor filters in several orientations and central frequencies.Based on these ideas,we present a new edge detection method using Gabor filter.Edges of different fineness are detected by using Gabor filtering edge operators in different orientation,and image edges are extracted through analyzing and fusing them...
