I have a dataset of 256 medical images. I am trying to classify the health lung vs diseased one. The resolution of images is too big around 5000 * 5000 of max. And not all the images are in the same size. So I planned to split the images into 256*256 pixels and create a bag with the split images and give them one label for the whole bag. then try Multiple instance learning. Can you please help me with this?
