对图像进行YCbCr分解
- rgb=imread('lena.png'); YCbCr=rgb2ycbcr(rgb); subplot(221),imshow(rgb),title('image'); Y=YCbCr(:,:,1); Cb=YCbCr(:,:,2); Cr=YCbCr(:,:,3); ycbcrmap(:,:,1)=Y; ycbcrmap(:,:,2)=128; ycbcrmap(:,:,3)=128; subplot(222),imshow(Y),title('Y'); ycbcrma
YCRCB2RGB.rar
- 我自己寫的RGB與YCbCr(YUV)色彩格式轉換,可以RGB轉YCbCr或YCbCr轉RGB,並支持顯示轉換後的色彩功能.,I wrote it myself RGB and YCbCr (YUV) color format conversion can be RGB or YCbCr to YCbCr to RGB, and supports the display of the color conversion function.
seg
- This a MATLAB code for segmentation of any image. Initially the image is converted from RGB to greyscale image and then segmantation is done.-This is a MATLAB code for segmentation of any image. Initially the image is converted from RGB to greyscale

surf2dxf
- The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.
