libjpeg-turbo: High-Performance JPEG Codec Library
libjpeg-turbo is a high-speed, high-quality JPEG codec that uses SIMD instructions (SSE2, AVX2, NEON, AltiVec) to accelerate JPEG compression and decompression. It is API and ABI compatible with the original IJG (Independent JPEG Group) libjpeg, making it a drop-in replacement for performance-critical applications.

LanguageProject Introduction
Summary
libjpeg-turbo is an open-source, high-performance library for encoding and decoding JPEG images. It is designed as a drop-in replacement for the original IJG libjpeg, offering substantial speed improvements through the use of SIMD instructions.
Problem Solved
The original IJG libjpeg, while widely used, can be a performance bottleneck in applications that require fast JPEG processing. libjpeg-turbo addresses this by optimizing the core algorithms using modern processor instructions.
Core Features
Hardware Accelerated Processing
