To determine the keypoint orientation, a gradient orientation histogram is computed in the neighbourhood of the keypoint.
为了定位特征值的指向,会使用到一个计算出的周围特征值的变换指向直方图来表示。
A novel gradient orientation histogram was built using a Gaussian-weighted circular window and a major orientation to each feature point was assigned based on local image properties.
构建了一种新的局部梯度方向直方图,同时定义了特征点的主方向,从而提出了一种具有旋转不变性的图像配准算法。
Recently, methods basing on histogram of orientation gradient are proved to be good for human detection.
