A Urinary Sediment Segmentation Algorithm of Cast and Epithelial Cells

Based on cast and epithelial cells to segment difficultly in urinary sediment, this paper propose one modified segmentation algorithm that is combining Sobel edge detection with edge enhancement algorithm, and using the fusion technology to get the whole binary results. Using cast and epithelial having great area is to remove small area impurity. Last after morphological operation can deserve a good split binary image. Experimental results show that the algorithm performs faster, complete binary cells and higher precision than segmentation algorithm from now on. The algorithm is not only suitable for cast and other large cells, but also satisfied for red and white cells, crystallize, sperm in urinary sediment.
