Description: JPEG标准中规定了4种压缩模式[15]：顺序编码（Sequential encoding），渐进编码（Progressive encoding），等级编码（Hierarchical encoding），无损编码（Lossless encoding）。应用最为广泛的为基于DCT变换的顺序编码，也称之为基准模式(Baseline mode)，其它几种模式都以此为基础。这里，采用了JPEG基准模式对图像进行压缩，在基准模式中，熵编码采用哈夫曼编码方法。
-JPEG standard specifies four kinds of compression [15]: the order of encoding (Sequential encoding), progressive encoding (Progressive encoding), class code (Hierarchical encoding), lossless encoding (Lossless encoding). The most widely used sequence-based DCT transform coding, also known as baseline model (Baseline mode), several other models are based. Here, using the JPEG image compression benchmark model, in the baseline model, the entropy coding using Huffman coding.

Description: libjpeg-turbo是对libjpeg的扩展，支持SIMD指令，如X86架构的MMX、SSE、SSE2、3DNOW，ARM架构的NEON，在对jpeg进行编码和解码的过程中能提高速度。-libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86, x86-64, and ARM systems. On such systems, libjpeg-turbo is generally 2-4x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. Platform: |
