I'm not sure how easy this is to add in (or if its been done already, i'm running and old version), but i've done some experimenting with similar images, and i've found that what seems to work is to desaturate the image, then increase the contrast of it (just like many captchas), i've got a sample convert command that will do just that, and makes gocr read quite a bit of the text afterwards

convert -modulate 100,0 -contrast -contrast -contrast -contrast -contrast -contrast -contrast -contrast -contrast -contrast -contrast -contrast -contrast -contrast -monochrome INPUT.GIF OUTPUT.GIF

(thats alot of -contrast anyone know how to specify multiple ones in a shorter line?)

i convert it to monochrome since i found it ends up leaving typically less artifacts afterwards and helps gocr alot.

Howzit guys, im struggling with the very same problem. I have gocr,ocrad,fuzzyocr but all the spams seems to be bypassing my setup. Is there any way i can tweak my fuzzy to scann all this spams with images embedded on?

Any help would be appreciated.

Kindest Regards, Lucky
