A SYSTEM AND METHOD FOR ESTIMATING COMPRESSION NOISE IN IMAGES |
| 摘要 |
A system and method for estimating compression image noise. Image data for an image is received. A compression ratio (115), an image size ratio (120), and an activity (135) for the image are determined (320, 330 and 340). Compression artifact estimation (150) is determined based on the compression ratio (115), the image size ratio (120), and the activity (135). |
