Optimized quantization method for compressing digital images |
| 摘要 |
<p>A method of compressing digital images, represented by pixel matrices, that employs the transform into the two-dimensional spatial frequency domain and a quantization process realized with matrices optimised in accordance with psycho-visual and statistical criteria, where the statistical criteria relate to specific image classes. <IMAGE></p> |
