after a lot of tryouts with different filters i have yet to accomplish getting a black and white image of the picture above.
I would like to have the text as readable as possible but using the 'log' filter is just not enough mixed with imadjust and midfilters
while the others doesnt help at all ,
could use a suggestion , thanks
You might want to try getting rid of the background gradient and maximize contrast by using CLAHE (contrast limited, locally adaptive histogram equalization), accomplished by the function "adapthisteq()" in the Image Processing Toolbox.
