Title image point operations based on DSP
Abstract
Digital image processing technology is very rich in content ,in general,digital image processing includes the following contents:○1point operations;○2geometry processing;○3image enhancement;○4image restoration;○5image morphological processing;○6image coding;○7image reconstruction;○8pattern recognition. This subject mainly introduces the point operations. Image point operations is an important issue for the field of digital image processing,and is also an important part of digital image processing,mainly including these three core parts:linear transformation,nonlinear transformation,histogram modification. This article describes the basic principles of the point operations, and then the treatment effect of various point operations and summarizes of the strengths and weaknesses of the various implementations are obtained by the Matlab simulation.Finally, the piecewise linear transformation and histogram equalization processing are completed on the DSP chamber.
