Baidu CFileDialog open file -- -- -- -- -- - this can choose the pictures from computer path

And then call the opencv correlation function for the image, can display images.

CodePudding user response:

Choose a picture from the browser, this action is manual to do? If is is according to the above said to select image by means of select files, if it is directly from a url to obtain images that will write an HTTP request to download the images

CodePudding user response:

You are under the MFC, is your choice, OpenFileDialog, choose to read, access to image path.
