FM Screening Based on Distribution Function and Its Optimized Algorithm Model

This paper sets continuous uniform distribution function on a,b ] interval as the basic generating model and creates an optimized algorithm model which can effectively improve FM dot structure. Firstly, distribution function model and its characteristics are analyzed, and then general FM dot generating method based on distribution function is provided. By carrying out 4 groups of random number experiments on different gray levels, this paper analyzes the random number charac- teristics of uniform distribution function and uses random numbers to generate FM dots, and then makes qualitative and quantitative researches on dot structure and characteristics. By deducing dot total circumference, a method to control dot gain is obtained, based on which an optimized algorithm model in terms of distribution function is established to improve dot structure. This algorithm model can effectively control dot total circumference. On the condition of ensuring FM dot characteristics, copying process can be simplified.
