Methods for converting digital radiographic image into analogue image simulating film in accordance with initial values pixel

摘要

For every pixel, it requires determining an analogue simulated pixel having film-like initial value y=(for i=1,M)sum(AiXpi+Bi); where Ai, Pi and Bi are real numbers and M is an integer value that is larger than or equal to 1. An image is printed on a transparent film in accordance with the initial values of the pixel.
