Ideas: Blank postcards don't have circles. The thought now is to take the color percentages. Blank postcard will be mostly background color.

How do we achieve this? We can binarize image-> if percentage of white is above a certain threshold, we can consider this postcard blank.

or:

We can use color thresholding. How do we get the desired min and max? We can take an average by sampling from the postcards that we have.

seems like binarizing is good way to achieve this. but first there is one more step:

There are some postcards that have a black border / white border. We want to crop this out to get the postcard only.

As of now black borders are able to be cropped. However, similar color borders pose a challenge.
