libjpeg-turbo

Compare

  Analyzed about 7 hours ago

libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors which uses SIMD instructions (MMX, SSE2, etc.) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4x as fast as the unmodified version of libjpeg, all else being equal. ... [More] libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but the TigerVNC and VirtualGL projects made numerous enhancements to the codec, including improved support for Mac OS X, 64-bit support, support for 32-bit and big endian pixel formats (RGBA, ABGR, etc.), accelerated Huffman encoding/decoding, and various bug fixes. The goal was to produce a fully open source codec that could replace the partially closed source TurboJPEG/IPP codec used by VirtualGL and TurboVNC. [Less]

Imebra

Compare

  No analysis available

Imebra is a multiplatform open source C++ Dicom library. The library can handle Dicom3, NEMA and Jpeg files and supplies both high-level and raw access to the loaded data. The embedded images can be easily decompressed or converted to other color formats or bit depth; writing Dicom Viewers or ... [More] other applications is a quick and easy task. Imebra also supports the Unicode standard (on the fly conversion to/from Dicom charsets) and the delayed-loading of large tags. [Less]
