Image
- 索贝尔算子(Sobel operator)是图像处理中的算子之一,主要用作边缘检测。在技术上,它是一离散性差分算子,用来运算图像亮度函数的梯度之近似值。在图像的任何一点使用此算子,将会产生对应的梯度矢量或是其法矢量 Sobel算子有两个,一个是检测水平边沿的;另一个是检测垂直平边沿的。Sobel算子另一种形式是各向同性Sobel (Isotropic Sobel)算子,也有两个,一个是检测水平边沿的,另一个是检测垂直边沿的各向同性Sobel算子和普通Sobel算子相比,它的位置加权系数更为准

ImgHOGFeature
- HOG特征计算,(1)将输入的彩图转换为灰度图; (2)采用Gamma校正法对输入图像进行颜色空间的标准化(归一化);目的是调节图像的对比度,降低图像局部的阴影和光照变化所造成的影响,同时可以抑制噪音的干扰; (3)计算梯度;主要是为了捕获轮廓信息,同时进一步弱化光照的干扰。 (4)将梯度投影到单元的梯度方向;目的是为局部图像区域提供一个编码, (5)将所有单元格在块上进行归一化;归一化能够更进一步对光照、阴影和边缘进行压缩,通常,每个单元格由多个不同的块共享,但它的归一化是基于不同块的
