Abstract
A system ( ) for generating image compression matrices is disclosed. The present invention includes an image ( ) having pixel block arrays ( ). The present invention also includes a transformer ( ) that performs discrete cosine transforms on the pixel block arrays ( ) to generate a discrete cosine transform array ( ). The present invention also includes a quantizer ( ) that receives the discrete cosine transform array ( ) and retrieves a quantization coefficient matrix ( ) and a model metric ( ). Quantizer ( ) partitions the quantization coefficient matrix ( ) with the model metric ( ) to generate a quantization matrix ( ). Quantizer ( ) also quantizes discrete cosine transform array ( ) with the quantization matrix ( ) to create a quantized array ( ). The present invention also includes an encoder ( ) that compresses the quantized array ( ).
