1) histograms of oriented gradients(HOG)
方向梯度直方图
1.
For the coarse scale images,the histograms of oriented gradients(HOG) descriptor is used to perform a nearest neighbor image matching,which neglects the disturbance of local texture,and complements the deformable layer graph matching method in both scale and computing speed.
对粗尺度图像提出基于方向梯度直方图算子的图像匹配算法,利用物体的整体形状信息进行全局匹配,能忽略局部纹理的干扰,并具有运算速度快的优点,且与分层图匹配算法在计算尺度图像及速度上形成互补。
