主要用于图像经小波变换压缩图像，并计算压缩后的图像压缩性能即压缩比和信噪比-Mainly used for image compression by wavelet transform image, and calculate the compressed image compression performance that the compression ratio and signal to noise ratio

提出一种结合小波变换与共现矩阵用于纺织品图像缺陷检测的方法。首先将灰度图像分解成子带 然 后将纹理图像分割成互不重叠的子窗口, 提取共现特征 最后用无缺陷样品训练的M ahalanob is分类器将每一子 窗口划分为缺陷的和无缺陷的。应用该算法进行实际工厂环境中的纺织品缺陷检测。实验结果表明, 集中处理 具有强判决能力的某一频带提高了检测性能, 也改善了计算效率。-Propose a wavelet transform and co-occurrence matrix for the
