Compression Research

Dr. Jin Li started his research career in Multimedia Compression. His noteworthy contribution are related to image/video/audio compression standard, include:

  1. Operational rate-distortion (R-D) optimality in embedded coding and sub-bitplane scanning (incorporated into JPEG 2000).
  2. Visual weighting and visual progressive compression (incorporated into JPEG 2000)
  3. Motion Compensated Lifting (a.k.a., Motion compensated temporal filtering) (incorporated into H.264/SVC)
  4. JPEG Interactive Protocol (JPIP) " (incorporated into JPEG 2000, Part 9)
  5. Arbitrary shape wavelet transform with phase alignment " (incorporated into MPEG 4, shape adaptive wavelet coding )
  6. Multiview Image Compression (pioneer work that leads to H.264 MVC)
  7. Scalable audio coding ( incorporated into MPEG 4, audio lossless format )

In his early career, he has implemented JPEG, MPEG-1, and JBIG, thereby gained hand-on knowledge of the inner working of the compression standards. He has won the best Ph.D. thesis award at Tsinghua University in 1994, for his work on variable block size motion compensation and a semi-object based video compression algorithm that significantly improves the performance of motion compensation for MPEG-1. 

From 1994-1996, Dr. Li joined Univ. of Southern California, in the Media Communications Lab of Prof. C.-C. Jay Kuo. From 1996-1999, he has joined Sharp Labs of America (SLA), and has represented the interest of SLA in JPEG 2000 and MPEG-4 standard activity. He joined Microsoft in 1999, first at Microsoft Research Asia(MSRA) (he has won a Microsoft gold star award in 2000 for his contribution in founding MSRA), and moved to Microsoft Research Redmond in 2001. He has worked on Fractal compression, video rate control, coding artifect removal, vector wavelet, wavelet packet, etc..
