How to use the software?

@KKyang
Hi yang. I built the project with Qt and got it run on my Win10. But after I loaded pgm image, nothing happened and I couldnot find any "run" button or something. So can you please tell me the steps to get the final detect result?
Thanks.

The application can only read PNG files. To convert the LJPEG image, you can take a look at the utility in reference 7. I didn't put the converted image on the Github cause I don't know if its legal or not.

There is a process button at the bottom-right corner of the application. I didn't write the UI to fit different resolutions, only resolutions larger then 1000x1080 will work properly. You may modify the Qt UI by yourself if your resolution doesn't reach the minimum requirement.

If the application works properly, once you load a PNG file and press process, an OpenCV imshow will appear for user to select the region they want.

The key bindings to the imshow window are:
a: confirm chosen area
b: clear chosen area
r: redo last step
x: exit

Click the left mouse to add the number of points of the initial contour.

The red contour is the calculated result, and the green contour is the ground truth. You'll have to use the utility to convert the ground truth given in the University of South Florida Digital Mammography Home Page Database.

Cheers.

@KKyang Thanks for your clear instruction. I loaded a PGM Image yesterday and maybe that's the reason I didnot see the process button. I will try again. Really appreciate your help.
