Method and apparatus for digital image rudundancy removal by selective quantization

A computer implemented method, apparatus, and computer usable code for identifying a set of foreground pixels in an image and a set of background pixels from pixels in the image. The set of foreground pixels is quantized using a first level of quantization to form a set of quantized foreground pixel...

Zusammenfassung:A computer implemented method, apparatus, and computer usable code for identifying a set of foreground pixels in an image and a set of background pixels from pixels in the image. The set of foreground pixels is quantized using a first level of quantization to form a set of quantized foreground pixels, and the set of background pixels is quantized using as second level of quantization to form a set of quantized background pixels.
