How to use Kornia to process tiff images and make them clearer

Download tiff image file:

you can try different equalization techniques: https://kornia.readthedocs.io/en/latest/enhance.html#equalization
there is a tutorial here too: https://kornia.github.io/tutorials/nbs/image_histogram.html

Unfortunately
Unable to adjust

It seems that it needs to be converted to HDR to adjust the details
But Kornia does not yet support converting HDR

[edgarriba]

@monkeycc can you suggest or contribute with a HDR conversion algorithm ?

Gimp
Sharpen (Unsharp Mask)
https://github.com/GNOME/gimp

Can be achieved
Gimp is open source
But I don't know how to look at the algorithm

in case of unsharp -> https://kornia.readthedocs.io/en/latest/filters.html#kornia.filters.unsharp_mask

[monkeycc]

sharpen = kornia.filters.UnsharpMask((9, 9), (10, 10))
sharpened_tensor = sharpen(data)
sharpened_image = kornia.utils.tensor_to_image(sharpened_tensor)

Unfortunately
Adjusted some parameters
Unable to perform clarity
