Last week I talked about displaying gray-scale and binary images. In that post, I showed how to control the grayscale range. For example, the call imshow(I,[0.4 0.6]) displays the matrix I as a... 更多内容 >>

In my previous posts (February 9, February 22, and February 29), I discussed the truecolor and indexed image display models in MATLAB, as well as the direct and scaled variations of indexed display. The Image Processing Toolbox has conventions for two additional image display models: grayscale and binary. These conventions are used by the MATLAB image display function imshow, which originated in the Image Processing Toolbox.... 更多内容 >>

In my last post on pixel colors, I described the truecolor and indexed image display models in MATLAB, and I promised to talk to soon about a third model. That model is the scaled indexed image, a... 更多内容 >>
