    "abstract": "This paper presents a method of lossless to lossy transcoding of images that takes advantage of bitplane coding in JPEG 2000. Decoding JPEG 2000 lossless codestreams and subsequently re-encoding them into JPEG 2000 lossy streams consumes lots of computational time. To reduce this time, partial decoding of the lossless codestream is proposed. In addition, by employing a unique rate control, the image quality degradation usually associated with partial decoding is reduced. Experimental results show dramatically reduced computational complexity while the subjective image quality closely approximates that of full lossless decoding.",

His activities have primarily focused on designing and implementing algorithms for image compression such as MPEG-4, AVC, and JPEG 2000. Fukuhara contributed to the standardization of JPEG 2000 and served as a project editor of JPEG 2000 Part1 amendment-1 and amendment-2. His current interest is image processing, image identification, and transcoding between different video compressed files, required for various applications including digital cinema. Fukuhara holds 39 U.S. patents in those fields and some of them are identified as essential patents for AVC by MPEG-LA. He is the first author of “JPEG 2000 Technology” (Japanese) published by CQ Publishing Co., Ltd. He was a recipient of the 1992 Institute of Electronics, Information, and Communication Engineers (IEICE) New Engineer Award for his work on intellectual image compression. He also won the 2007 IPSJ Contribution to International Standardization award for his work on JPEG 2000.",
