可以y9ng捱三顶四都v大少吃点 阿少吃点奥迪车爱迪生v大dsca点撒(You can y9ng endure three four are v A large eat less eat less Audi Edison v big dsca point spread)

将彩色图像以RGB分为三层，使用直方图对其对比度进行调整，产生预定义的滤波器对图像进行滤波，最后实现图像的增强(RGB color image is divided into three layers, using the histogram to adjust its contrast, produce predefined filters for image filtering, image enhancement and finally realize)

进一步采用基于距离和曲线形态的双尺度相似性度量谱聚类算法进行聚类处理，通过求n 个二次规划问题，就可以求得相似度矩阵W，降低了谱聚类算法对参数的敏感性，使算法更稳定(Furthermore, we use the two-scale similarity measure spectrum clustering algorithm based on distance and curve shape to carry out clustering. By finding n quadratic programming problems, we can obtain the similarity matrix W and reduce the sensitivity of the spectral clustering algorithm to the parameters Sex, make the algorithm more stable)
