python opencv image size transformation method

The following editor will share with you an article on python opencv image size conversion method, which has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor and take a look.

Using cv.Resize (source, target, transformation method) in Python OpenCV, you can transform it into the desired size

Source file: Needless to say

Target:You can zoom in and out of the image or input it directly Size

Transformation method:

CV_INTER_NN - nearest neighbor interpolation,

CV_INTER_LINEAR - bilinear interpolation (missing Use less)

CV_INTER_AREA - Use pixel relational resampling. This method can avoid ripples when the image is zoomed out. When the image is enlarged, it is similar to the CV_INTER_NN method..

CV_INTER_CUBIC - cubic interpolation.

For example, I want to change a picture into a 32*32 size

 image=cv2.imread('test.jpg')
 res=cv2.resize(image,(32,32),interpolation=cv2.INTER_CUBIC)
 cv2.imshow('iker',res)
 cv2.imshow('image',image)
 cv2.waitKey(0)
 cv2.destoryAllWindows()

Of course, you must import the opencv library normally. I have tried many of them on the Harbin Internet and are outdated
