Just Noticeable Difference (JND) model in transform domain is determined by the contrast sensitivity function, luminance masking and contrast masking. In this paper, we propose an improved JND model with a new method for contrast masking factor estimation. We decompose an image into structural image and textural image, and the textural image is used for an(More)
In scalable video coding, spatial scalability is a layered video representation with different spatial resolutions for the same video signal. Inter-layer motion information prediction is a method of improving coding performance for spatial scalability. In this paper, a multi-domain motion vectors prediction coding method for spatial scalability is proposed(More)
