Touching blood cell image segmentation based on improved fractional order differentiation and graph theory
摘要
Abstract
For blurring and low contrast of the blood cell images, an image preprocessing method based on improved fractional differential was put forward. This method was combined with morphologi-cal denoising processing and improved round mask operator of fractional differential enhancement, fil-tering the staining contamination and grain noise of the blood cell images, and retaining the edge de-tails of the cells. Also an improved cell image segmentation algorithm based on watershed algorithm and minimum spanning tree ( MST) algorithm was proposed, which solved the problem of low efficiency and over-segmentation. The pre-processed cell images were split by watershed algorithm. Then, the o-ver-segmentation areas were mapped to nodes. At forwards, the cell images were segmented by the im-proved MST algorithm. The new algorithm can alleviate the over-segmentation problem of watershed al-gorithm, and effectively reduce the number of nodes in MST algorithm. Experimental results indicate that the studied algorithm is ideal and effective.关键词
