Abstract
A method for generating image compression quantization matrices is disclosed. A method includes a step of locating a frequency coefficient ( ) within a transform array ( ). A method also includes a step determining a frequency content ( ) for the frequency coefficient ( ). Method also includes the step of determining the orientation content for the frequency coefficient ( ). The method also includes the step of selecting a quantization matrix ( ) correlating to the frequency content ( ) and the orientation content. The method also includes the step of quantizing the transform array ( ) with the quantization matrix ( ).
