Here is Bruce's Shorts' episode 31 of series 2: JPEG 2000 The Basics
NEC has released StarPixel, an image codec that achieves a compression ratio similar to JPEG2000, while keeping the image processing load below that of JPEG. NEC developed StarPixel using its own image conversion and encoding technology.
A version that enables lossless compression has been included in the Venus probe Akatsuki. In addition, Hayabusa 2, a planetary explorer scheduled for launch in 2014, will have both lossless and lossy versions.
"In this demo with a moving car, the side camera captures 120 frames per second. On the right side of the screen, the pictures are compressed and restored using StarPixel in real time at 120 fps. It seems to be handled easily, but compressing, restoring, and displaying pictures at 120 fps on an ordinary PC can't be done unless the processing load is low."
In software compression tests using color images, compared with JPEG2000, compression speed was 10-40 times higher for a similar compression ratio, and expansion speed was 6-13 times higher.
This technology is also being used in a road image gathering system by the NEXCO West Japan Group.
"For expressway maintenance, roads are photographed at high speed - tens of frames per second. Until now, the pictures have been stored without compression. But now, using StarPixel, we can take pictures and store them on PC in real time, reducing the amount of image data by about half. This means we can photograph double the length of road in the same time. This is one example of how StarPixel's advantages are emerging."
StarPixel is provided as a standard Windows DLL, enabling it to be quickly embedded in various current image processing systems. NEC aims to sell 10,000 licenses during the next three years.

Introducing Comprimato a unique jpeg2000 encoder and decoder. Comprimato is a software ad-on that can decode and encode UHD video into jpeg2000 at very high performance. Comprimato is different to other encoding systems, because it uses the power of a graphics card.
Comprimato can tune up almost any software or hardware. By adding the Comprimato library into your code, you have a chance to speed up your workflow to real time speeds or even faster. Comprimato works on normal PCs with a powerful NVIDIA graphics card. Thats why it is easy to integrate into your processing production line.

JPEG 2000
JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created in 1992) with a newly designed, wavelet-based method. The standardized filename extension is .jp2 for ISO/IEC 15444-1 conforming files and .jpx for the extended part-2 specifications, published as ISO/IEC 15444-2. The registered MIME types are defined in RFC 3745. For ISO/IEC 15444-1 it is image/jp2.
JPEG 2000 code streams are regions of interest that offer several mechanisms to support spatial random access or region of interest access at varying degrees of granularity. It is possible to store different parts of the same picture using different quality.
Aims of the standard
While there is a modest increase in compression performance of JPEG 2000 compared to JPEG, the main advantage offered by JPEG 2000 is the significant flexibility of the codestream. The codestream obtained after compression of an image with JPEG 2000 is scalable in nature, meaning that it can be decoded in a number of ways; for instance, by truncating the codestream at any point, one may obtain a representation of the image at a lower resolution, or signal-to-noise ratio – see scalable compression. By ordering the codestream in various ways, applications can achieve significant performance increases. However, as a consequence of this flexibility, JPEG 2000 requires encoders/decoders that are complex and computationally demanding. Another difference, in comparison with JPEG, is in terms of visual artifacts: JPEG 2000 only produces ringing artifacts, manifested as blur and rings near edges in the image, while JPEG produces both ringing artifacts and 'blocking' artifacts, due to its 8×8 blocks.
