Abstract
An anti-aliasing filter comprised by a first filter kernel is applied to the medical image data so as to obtain filtered image data. The filtered image data is downsampled so as to obtain decimated image data, and pixel resolution of the decimated image data is approximately one half of pixel resolution of the image data for the medical image. The decimated image data is upsampled and an interpolation filter is applied so as to obtain interpolated image data. The interpolation filter is comprised by a second filter kernel, and the size of the first kernel is smaller than the size of the second filter kernel. Pixel resolution of the interpolated image data is approximately equal to pixel resolution of the medical image data. Difference image data between the interpolated image data and the medical image data for the medical image is obtained, and the difference image data is displayed.
