About The human visual system focuses on active areas in images, such as people or vehicles. This project introduces a lossy encoder using image segmentation to guide quantization, improving ...

We collect the mean opinion scores for a designed image test set containing compressed images for three different quantization schemes, and show by numerical analysis of 300 test images ofTAMPERE17 ...

We introduce multi-variate block polar quantization (MBPQ). MBPQ minimizes a weighted distortion for a set of complex variables representing one block of a signal under a resolution constraint for the ...
