1. A medical image processing device, comprising: a processor configured to: extract an anatomical feature point included in a medical image based on the medical image; acquire standardization conditions of pixel values of the medical image based on some pixel values around the anatomical feature point among the pixel values of the medical image; and perform region extraction processing for extracting an anatomical region included in the medical image based on the standardization conditions and the medical image, wherein the processor generates a conversion image by performing conversion processing on each pixel value of the medical image based on a statistical quantity that is calculated based on pixel values around each pixel value, and extracts the anatomical feature point based on the conversion image, and wherein the conversion processing calculates an average value Mlocal and a standard deviation SDlocal from the pixel values of pixels surrounding the each pixel and calculates each pixel value Ic(x, y) of the conversion image by using the following Equation 
 Ic ( x,y )=( I ( x,y )− M local)×Const/ SD local wherein x, y represent coordinate values of the each pixel of the medical image and Const is a constant set in advance.
