motionBlur

• 基于opencv2的模糊

def motionBlur(img,size=3):
    # 默认生成一个[0 0 0
                1 1 1
                0 0 0]的核
    kernel_motion_blur = np.zeros((size, size))
    kernel_motion_blur[int((size-1)/2), :] = np.ones(size)
    kernel_motion_blur = kernel_motion_blur / size
    # 应用opencv2的滤波函数
    output = cv2.filter2D(img, -1, kernel_motion_blur)
    return output
