I have the following image of a document
And I want to be able to detect the images at the top of the page. I tried using line detection using erosion and dilation to get bounding boxes around the images but that did not work because the edge of the images contain many different colors, so the detected lines do not form a box.
Can anyone think of a better approach to detecting these images. Perhaps exploiting the fact that the images have color and the rest of the document is black and white. However, a this approach would not be ideal for the case when the images themselves are black and white.
