A quality prediction model for images coded with JPEG is proposed in this paper. This model estimates the quality of an image at a given compressed ratio based on the structural similarity theory, without actual coding of the image. As different frequencies play various roles in human vision, the frequency sensitivity-based structural similarity model is introduced in this paper. The proposed model...
A fast and effective fade detection algorithm is proposed in this paper, which directly operates in compressed domain and suitable for real-time implementation. By analyzing the prediction directions of B frames, which are revealed in the macroblock types, the candidate fades can be found. Then, uncommon intracoded macroblocks of the P frame can be applied as an indicator of fade. As a result, locating...
