JPEGCompression
编码:
(1)进行颜色转换,将RGB格式转换为YUV格式。
(2)将待编码的N×N的图像分解成(N/8)^ 2 个大小为8×8的子图像。
(3)对每个子图像进行DCT变换,得到各子图像的变换系数。这一步的实质是把空间域表示的图像转换成频率域表示的图像。
(4)对变换系数进行量化。
(5)进行Z字形重排
(6)使用霍夫曼变长变码编码器对量化的系数进行编码,得到压缩后的图像(数据)。
解码:
(1) 对压缩的图像数据进行解码,得到用量化系数表示的图像数据。
(2) 进行反Z字型重排
(3)用与编码时相同的量化函数或量化值表对用量化系数表示的图像数据进行逆量化,得到每个子图像的变换系数。
(4)对逆量化得到的每个子图像的变换系数进行反向正交变换(如反向DCT变换等),得到(N/8)^2 个大小为8×8的子图像。
(5)将(N/8)^2 个大小为8×8的子图像重构成一个N×N的图像。
(6)进行颜色组合,将YUV格式转换为RGB格式图像。(JPEG compression and decompression process)

discrim_rf
斯坦福大学的姚邦鹏开发的一个图像分类算法,使用random forest实现了图像的精细区域描述,赢得了PASCAL VOC2011图像分类竞赛中的winner prize.经测试,程序完全可运行,且提供了MAC和Windows下的两种程序。(Image Classification: An Integration of Randomization and Discrimination
in A Dense Feature Representation
The goal of our method is to identify the discriminative fine-grained image region that distinguishes different classes. To achieve this goal we sample image regions from dense sampling space and use a random forest algorithm with discriminative classifier. Each node of the tree of random forest is trained and tested with fine-grained image patches combining the information from upstream nodes together. We implemented each node of the tree with a discriminative SVM classifier, which makes the node as a strong classifier. )
