At this website QualVisual.net, we demonstrate our research results on data compression and system compression. We have designed a variety of advanced algorithms for high quality image/video coding and high efficiency image acquisition.

Lucid is our software product on data compression. It pursues and excels at high quality image coding. Based on our new algorithm, it may noticeably improve image quality compared to existing technologies, including JPEG (1989), JPEG2000 (1999), JPEG XR (2009) and Google WebP (2011).

Rapid is our software product on high efficiency imaging. It fulfills our proposal of system compression paradigm.  To accelerate image data acquisition, we devised new mathematical transforms and methods. It may effectively improve medical imaging efficiency, without loss of image visual quality. Click here to see details.

Thirdly, we designed new entropy coding method for high quality video coding. We modify the entropy coding mechanism of H.264 and HEVC. The new method fulfills our proposal of a new approach to time-frequency analysis. It may help to improve coding efficiency over CABAC with much lower algorithmic complexity.  Especially, the new method may significantly improve compression performance in scalable video coding than H.264/SVC and drastically reduce computational complexity.  Click here to see details.

Based on test model HM 6.0, we have successfully developed the next generation video coding standard HEVC (H.265), with code optimization in software implementation for fast computation.

One picture is worth a thousand words, but it takes thousands times more data. We strive to make new technology for people to  ---  see a better world in less data.
