Hello everyone,

I have a 640x480 pixels photo.

I'm considering applying an average(mean) filter for the example (105,145) pixel.

Opencv have cv2.blur() function.

But this function applies average filter to all pixels.

I want to apply it to any pixel.

Does anyone have any suggestions?

Thanks.

please explain, what the mean of a single pixel should be (it does not make any sense to me)

did you mean: filtering a small region, a roi ?

Sorry for not telling you. E.g. I have a 100x100 pixels photo. The pixel in the 50. row and 50. column of the photo has no value. But other pixels have value. I want to find this value using the average of the pixels that are close to its surroundings.

In other words, I want to assign RGB value to the 50. row and 50. column based on the pixels around it.

That is called inpainting.

[edit] By the way, the inpainting is a more intelligent method than getting a mean of the surrounding pixels. It tries to recreate the texture and other structural elements of the missing zone.

Sounds very similar to whats happening the convolution layer(s).
