英文摘要
In this research we have developed efficient algorithms for reporting all the grid points within a given convex polygon in optimal time and also applied the algorithm for two-dimensional integer programming. We have also implemented those algorithms using C language and evaluated their practical efficiencies.The results were quite satisfactory. We further extended the similar idea to some other problems : digital halftoning of pictures of multiple brightness levels and that of detecting all possible digital components of a specified curve in a digital picture.
