Abstract
Along with the development of correlation domain of calculator sense of vision, machine sense of vision and so on, picture processing development is very quick.
Under the trend of the times impetus, this text carried on study and research to the colored image edge examination technique especially. In the article, there is an introduction of a set of complete colored picture edge examination procedures. And at processing picture with different effect, the procedures can use several kinds of classical operators, like Sable and Kirsch . Also the text has enumerated some other operators, just like Laplacian and Prewitt and has made the effective contrast between these operators.
It has clear demonstrated the merit and shortcoming of these 4 kinds of operators in the experiment’s result. The user can according to oneself need to choose the appropriate method to carry on the work and the research.
