An Integrated Color-Spatial Approach for Content-Based Image Retrieval

An electronic copying machine including apparatus for supplying one of at least two sizes of paper has a transparent surface for receiving a paper to be copied, a lid for covering the paper during copying, a light sensor mounted beneath the surface for directing light at a predetermined wavelength to the surface and detecting the light reflected from the surface, a first roller drive for supplying a first size of paper when the light sensor detects that the paper to be copied is that first size and a second roller drive for supplying a second size of paper when the light sensor detects the paper to be copied is the second size.
