I need help in removing the text appering on the image while preserving the background. The text can be at any position in image.

Input Image is: image description

and the required output is: image description

Please suggest me the way how can I achieve this.

Thanks in advance.

Here is simple because it is black on white, and the letters are not bold, so applying a blur there or even a similar white, it will not be seen, but normally you should do inpainting. And for that you need to detect the text, that is: you will need the text mask, where you need to apply the inpainting method.

I also have other images with coloured background; if i proceed as you said, then i have following problems arising: 1. noises in the image.. several other parts of image get detected as text 2. by applying inpainting..patch is visible in image

Honestly, this is a case where you could use MS Paint. But I assume you want to do it programmatically ;)

Have you tried opencv inpaint? Example

void inpaint(InputArray src, InputArray inpaintMask, OutputArray dst, double inpaintRadius, int flags)


  1. Text recognition
  2. Build "inpaintMask" with positions of the text
  3. Call inpaint
