1. A method of compressing a frame in an image compression and storage system, the method comprising:
receiving an original sample of the frame;
selecting, by a quantizer, an index corresponding to a quantization band based on the original sample;
outputting, by an inverse quantizer, a maximum value of the quantization band as a dequantized value based on the index; and
generating a reconstructed version of the original sample based on the dequantized value.
