DIGITAL FILTER FOR REDUCTING BLOCKING ARTIFACTS IN IMAGES |
摘要 |
The present application relates to a digital filter for reducing blocking artifacts in images digital data filtering circuit is able to implement the calculation steps of a discrete transform of a set of 8 original data (w), and calculating an inverse discrete transform of the set of transformed data thus obtained. For this purpose, it comprises a first filtering module (FILol) intended to filter the odd transformed data or the 3 odd transformed data items having the highest frequencies in the set of transformed data, and a second filtering module (FILo2) connected to the first filtering module and intended to filter the 2 odd transformed data having the highest frequencies in the set of transformed data. |
