In the H.264/AVC coding standard, there are seven motion estimation modes from 4×4 to 16×16 are used to find the minimum motion compensation error for each macroblock in the inter frame coding. For intra prediction coding, four prediction modes are used to encode the 8x8 chroma and 16x16 luma blocks and eight prediction directions and one DC(More)
In this paper, we propose a novel image-based facial expression recognition method called "expression transition" to identify six kinds of facial expressions (anger, fear, happiness, neutral, sadness, and surprise) at low-resolution images. Two approaches: direct mapping and singular value decomposition (SVD) are applied to calculate the expression(More)
