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)

Local-Binary-Patterns
局部二进制模式,LBP,是已被用于纹理特征的一个
分类。在本文中,提出了一种基于使用这些功能的方法
检测缺陷图案的面料。在培训阶段,在第一个步骤LBP算子是
施加到无缺陷织物样品,逐个象素和参考的所有的行(列)
特征矢量的计算。那么这个图像被分为Windows和LBP算子是
应用这些窗口的每一行(列)。根据与参考比较
特征向量一个合适的阈值,无缺陷的窗户被发现。在检测阶段中,一个
测试图像被划分成的窗户,并使用阈值时,有缺陷的窗口可以
检测到。该方法简单,灰度不变。由于其简单性,
线上实现是可能的。(Local Binary Patterns, LBP, is one of the features which has been used for texture
classification. In this paper, a method based on using these features is proposed for
detecting defects in patterned fabrics. In the training stage, at first step LBP operator is
applied to all rows (columns) of a defect free fabric sample, pixel by pixel, and the reference
feature vector is computed. Then this image is divided into windows and LBP operator is
applied to each row (column) of these windows. Based on comparison with the reference
feature vector a suitable threshold for defect free windows is found. In the detection stage, a
test image is divided into windows and using the threshold, defective windows can be
detected. The proposed method is simple and gray scale invariant. Because of its simplicity,
online implementation is possible as well. )
