dct- computes de discrete cosine transform for a matriz 8*8 from a picture.It receaves the point of the block where begin calculate, the tam of the block and the original picture... lLoyd-max- computes de lLoyd-max optimum quantizer for N bits.

Implementation of a Max Lloyd quantizer using matlab for grey scale images. The quantizer uses random starting conditions and find the locally optimal quantizer levels.
