You need to scan your document with something like stdfilt() with the proper size window to identify blocks of text. It will have high values, whereas smooth areas like photos and white space will have low values, Then you can threshold the stdfilt image and use bwareaopen() to look for appropriate sized areas or use regionprops and look for rectangular shaped areas.

It will get you the entire block of text. If you want to find paragraphs within that, it looks like you can scan down the image, getting the block sum as a function of column number. The columns that start paragraphs will have a lower sum since there are no pixels there.
