解决方法
这是在Python / OpenCV中执行此操作的方法。
首先,使用INTER_AREA调整大小。此外,调整大小并备份。
输入:
import cv2
# read the input
img = cv2.imread("barn.jpg")
hh,ww = img.shape[:2]
# resize down,then back up
w,h = (16,16)
result = cv2.resize(img,(w,h),interpolation=cv2.INTER_AREA)
result = cv2.resize(result,(ww,hh),interpolation=cv2.INTER_AREA)
# save result
cv2.imwrite("barn_pixelated.png",result)
# show result
cv2.imshow("result",result)
cv2.waitKey(0)
cv2.destroyAllWindows()
