I should use OCR for detecting texts in many pictures. Here is one of the samples. image description

Also it is the picture after using adaptive threshold filter. image description

If you see carefully, you can recognize "9408 M 80 M01213" in this picture.

I would be appreciate if somebody helps me to make the last picture more clear for using an OCR library(like tesseract) or suggests me any other filters.

Another way big blur of size 15 with sigma 10 and resize your image (813/8 and 1561/8) it will give you something like this
