Python + OpenCV模糊处理(Bluring)

模糊处理在边沿检测和去噪声方面有较为广泛的应用。OpenCV中提供了4种模糊算法，列举如下：

• average
• median
• gaussian
• bilateral

本文将分别采用这4种算法对同一幅图像进行处理，并以图像的形式展现这几种算法之间的差别。

1 average

代码如下

    import numpy
    import argparse
    import cv2

    image = cv2.imread('1.jpg')
    cv2.imshow("Original", image)

    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    cv2.imshow("Gray", gray)


    #[x,y] is the kernel for bluring
    #the large kernel becomes, the more blurred imag will appear
    #hstack is able to stack multiple images together
    #using simple mean to average
    blurred = numpy.hstack([
    cv2.blur(gray, (3,3)),
    cv2.blur(gray, (5,5)),
    cv2.blur(gray, (7,7))])

    #display two images in a figure
