A Novel Digital Image Segmentation Method Using Sharp Edge Detection by Fuzzy Inference System
Subscribe/Renew Journal
Image segmentation partitions the image space into some non-overlapping meaningful homogeneous regions. These regions should have a strong correlation with the objects in the image. The success of an image analysis system depends on the quality of segmentation. Edge detection is a critical element in image processing, since edges contain a major function of image information. The function of edge detection is to identify the boundaries of homogeneous regions in an image based on properties such as intensity and texture. Many edge detection algorithms have been developed based on computation of the intensity gradient vector, which, in general, is sensitive to noise in the image. In order to suppress the noise, the operator based on fuzzy technique is introduced in order to simulate at a mathematical level the compensatory behavior in process of decision making or subjective evaluation. The following paper introduces such operators on hand of computer vision application.
In this paper, a novel method based on fuzzy inference system reasoning strategy is proposed for edge detection in digital images without determining the threshold value. The proposed approach begins by segmenting the images into regions using floating 3×3 binary matrices. The edge pixels are mapped to a range of values distinct from each other. The robustness of the proposed method results for different captured images are compared to those obtained with the linear Sobel operator. It is gave a permanent effect in the lines smoothness and straightness for the straight lines and good roundness for the curved lines. In the same time the corners get sharper and can be defined easily for both gray and color images.
