SVMs are considered by many to be the most powerful 'black box' learning algorithm, and by posing构建 a cleverly-chosen optimization objective优化目标, one of the most widely used learning algorithms today. 第一节 向量的内积(SVM的基本数学知识) Support Vector Machines 支持向

Bilateral Filtering for Gray and Color Images 双边滤波器:保留边界的平滑滤波器. 在局部上,就是在灰度值差异不大的区域平滑,在灰度值差异比较大的边界地区保留边界.所以双边滤波器作用于每个像素的同时,必然会受到领域像素点的距离.灰度值差的权重影响. 已知低通滤波可以表示为: range filter可以表示为:(range filter 试选定一个数值范围,再做滤波的一个操作) 所以,双边滤波器的定义是: 其中,k(x)是归一化(normalize)函
