Abstract
The present algorithm aims to make use of wide register-width of recent microprocessois, for digital image processing. It offers simultaneous processing method of multiple pixel data which are packed in a long register.
In this paper, a simultaneous subtraction algorithm is explained first, then some examples are shown to prove. the effectiveness of the method. As applications of the algorithm, a new binarization method and simultaneous calculation of four absolutes differences. are proposed. For the four-pixel simultaneous binarization, the computation time becomes half comparing to that of an ordinary method. For the latter .calculation, it is shorten only 10% in the worst case, and 40% in the best condition. The performances are varies depending on an operating system and CPUs.
