The regular NLM takes a lot of time - what should I do?
|
The NLM, as described, assumes that for each pixel, the average is done over the entire image. It might be a good idea to only compute the average over close-by pixels, and not the entire image. Play with the value of "close-by" to find a good result. |
Task 8 - The denoising function needs a directory to write the results to,
and it is not provided in task 8. What do we do?
|
Create IN tmpDir a directory Result and give this folder to the denoising function. (While experimenting for parameters, it would be wise to delete this folder every experiment so your disk won't fill up |
Adding noise to image -
we get values outside [0,255] -
should we leave them as is,
or truncate them?
|
To make the simulations realistic, images after adding noise should be truncated, i.e., any value below 0 should be set to 0, and any value above 255 should be set to 255. This violates slightly the Gaussian noise assumption, but it is more realistic. |
