Hi
As you know mini-MIAS dataset contains mammogarm images.
I have a problem. I show you one of the imges which I have determined the location of abnormality based on the coordinates I have from this page:
http://peipa.essex.ac.uk/info/mias.html
for image : mdb028 F CIRC M 338 314 56
the corresponding image is attached.
I think the coordinates doesn't match the abnormality.
if you see the attached image, it is clear that in this coordinate , No abnormality exist.
please help me if I think wrong.I am waiting for your response.
The coordinates are from the bottom left corner. The image posted is a factor of 2 down samples. The Center of Mass of the lesion is 167 right and 155 up. Given the scaling factor this means the coordinates that you have are correct. I hope this helps.
I have the same problem.
Could you please explain more how to resolve it?

l'image a été redimensionnée, donc, les coordonnées (x, y) doivent également être ajustées.
I have read all the previous anwers. However, I didn't find out the due process of adjusting the ground truth coordinates taking into account the 2 down sampling aforementioned, in order to get the location to a coordinate system with origin in the top left corner. Could anyone please helps or explains me the operantions? Are they just arithmetic operations? How is it? I will appreciate it.
