hi!

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)

Steps???:

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