mauriciopt	Posted - Feb 05 2020 : 04:08:44 Hi, after some tests, UnsharpMask is not the solution. I think it would be new function to prepare image for OCR that can "clean" the shape od the caracters. Mauricio http://sourceforge.net/projects/tcycomponents/

spetric	Posted - Jan 29 2020 : 14:28:26 Hi, You can try with unsharp mask tool (TImageEnProc.UnsharpMask). It's very useful for sharpening blurred images.
mauriciopt	Posted - Jan 29 2020 : 13:58:41 Hi, thanks for your response. I already use ImageEnMView.Proc.ConvertToBWLocalThreshold(24); Using 140 is too long and OCR result is not better. I would like something not too bold. Maybe creating a new function specific for OCR jobs that will clear caracters like my image.

aleatprog	Posted - Jan 29 2020 : 11:12:56 ImageEnView.Proc.ConvertToBWThreshold(140); I tested your image and a value between 100 and 180 should be ok. Al
