GPU JPEG Compression We have createdFast GPU JPEG codecfor NVIDIA GPU. We got ultra fast GPUJPEG compression and decompression due to parallel implementation of Baseline JPEG algorithm. Our GPU JPEG codec is much faster in comparison with the best commercial multithreaded JPEG codecs for multicore...
The compression ratio and PSNR values are different for different images. It is found that performance will not remain same for different images even though compression factor was same.E. E. PhyoN. AyeAye HtweE. E. Phyo. Nang Aye Aye Htwe, "JPEG Image Compression and Decompression using ...

JPEG compression and decompression objects are two separate struct types. However, they share some common fields, and certain routines such as jpeg_destroy() can work on either type of object. The JPEG library has no static variables: all state is in the compression ...

libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On ...

JPEGis a lossy compression algorithm developed by the Joint Photographic Experts Group–thus the name– to apply controllable levels of compression to digital image files to reduce their byte sizes. Also note thatJPEGis aCODEC, compression, and decompression standard, not a file format. It is fun...
Compression for JPEG-LS is generally much faster than JPEG 2000 and muchbetterthan the original lossless JPEG standard. Compression for JPEG-LS is generally slightlyworsethan JPEG 2000, but this highly depends on the image content. Decompression for JPEG-LS is generally much faster than JPEG 2000...
