Edge-Enhancement in Intra Prediction Algorithm for H.264 [ READ ]
Maha Sharkas, Mohamed E. Khedr, Abdusalam Z. Adham
In an H.264 Advanced Video Coding system, an intra-prediction tool that uses neighbor picture elements within the current picture has been adopted for enhancing compression efficiency. In this paper, a new efficient H.264 intra prediction scheme is proposed. The new prediction scheme is called Modified Prediction Matrix Mode (MPMM). The main idea behind the proposed prediction algorithm is to differentiate between the best suitable intra predictions pixels, {vertical - horizontal}. The performance of our proposed modification is evaluated using Mat Lab code. The results show that our MPMM enhances the Peak Signal to Noise Ratio (PSNR) in addition to giving a clue for the object's edge pattern.
