Sample Result. The original image is in the upper left corner. The image in the upper right corner is the image after cropping it to the region in which bone is found and histogram equalization. It can be observed that histogram accentuates the appearance of arteries in the center of the image. In the lower left corner is the image after Speckle Reducing Anisotropic Diffusion (SRAD) filtering. In the lower right corner are results of segmentation. The edges of the segmentation results are clearly defined and segmented objects are correctly representing the location, shape and size of the bones visible in the raw image.
