I am working on Color recognition, but my app response is very slow on iphone 4s/4. I checked the speed of code line by line and it take almost half when loop iterate 320*480 (width and height of image), but if we'll resize image (let say 100*100) then speed enhance, but i don't know at where i have to resize image so that its output will not be damage. So need your help to do this. Thanks in advance.

Which SDK are you using? - the Unity extension or the native iOS SDK?
Take a look at our Background Texture Access sample. This demonstrates how to map the camera image to a texture, which you should be able to scale for your purposes.
