I have collected dirty background images, below is the sample:
I have also a collection of an actual image of a dirty document with text on it, just like below:
My problem with my actual image of a dirty documents with text, is that the text is not written in English alphabet. So, my task is to create old documents with English text written on it. All I have to do is to overlay any English text to a blank dirty document.
After overlaying, my task is to find a measure which shows that the synthetically generated dirty document with English text is almost the same with my collection of original dirty documents with not-English text. Maybe I can compare their histograms and whatsoever, to find their commonality. Help me find that measure. The purpose of finding that measure is to ensure that synthetically generated documents have the same quality as the original ones within a specific range of threshold.
I will use the synthetically generated documents as the data for my research, and I need to ensure that the data I will be using is as good as the original one.
