The watershed algorithm is one of the most powerful morphological tools for image segmentation, but the traditional watershed algorithm always exists serious over-segmentation, and can be easily affected by specularities and shadows. A new image segmentation based on reconstruction labeling watershed algorithm in color space is proposed to solve these problems. First, the RGB color image is converted...
In order to overcome the traditional Otsu algorithm weakness in the complex image segmentation, a new segmentation algorithm was introduced in this paper to detect the surface defect of parts, which applied with morphology and wavelet transform into the Otsu algorithm. There were two steps in the algorithm, one was segmentation target from the background and the other was segmentation defect from...
This paper proposes an image enhancement algorithm based on fuzzy theory. The average of all adjacent points is as enhancement threshold and affiliation of each point is obtained by counting the average. Then, enhancement images are obtained with inverse transformation. Experiments have proved that contrast of vein and background is enhanced and effect of image segmentation and extraction is improved...
