ทดลองเปิดภาพเป็นโทนสีเทา แล้วใช้ Median filter ผลที่ได้ภาพจะเบลอ

import pyopencv as cv

filename = r’violet.jpg’
inImage = cv.imread(filename,cv.CV_LOAD_IMAGE_GRAYSCALE)
outImage = cv.imread(filename,cv.CV_LOAD_IMAGE_GRAYSCALE)

cv.smooth(inImage,outImage,cv.CV_MEDIAN)

cv.imshow(“PyopenCV: input image”,inImage)
cv.imshow(“PyopenCV: output image”,outImage)
cv.waitKey(0)

Image

คงต้องกดดูภาพขนาดเต็มจึงจะเห็นความเปลี่ยนแปลง
