Segmentation of kidney without using contrast medium on abdominal CT image

This paper is a study of the segmentation of a normal kidney, grasping the special quality of the abdominal CT image, analyzing the kidney and implementing automatic segmentation of the kidney. In processing, the organ extraction was executed using the character of each other pixel distribution of each organ and extracted kidney in a single slide. This process is done through subtraction and processing of filling using a template while the binary image gets through the threshold. We removed the noise without removing the folding of each slide of the extracted kidney image in a single slice.
