1、函数原型声明和相应参数的解释
在这里告诫大家,关于OpenCV中一些函数的使用,最好去读英文原版注释,这样才能更深刻的去了解用途。
函数原型:
cv2.HOGDescriptor(win_size = (64, 128),
block_size = (16, 16),
block_stride = (8, 8),
cell_size = (8, 8),
nbins = 9,
win_sigma = DEFAULT_WIN_SIGMA,
threshold_L2hys = 0.2,
gamma_correction = true,
nlevels = DEFAULT_NLEVELS)
具体参数介绍(parameters):
win_size – Size ##窗口的大小
Size of detection window in pixels (width, height). Defines the region of interest. Must be an integer multiple of cell size.
block_size – Size ## 块的大小
Block size in pixels (width, height). Defines how many cells are in each block. Must be an integer multiple of cell size and it must be smaller than the detection window. The smaller the block the finer detail y
