I was thinking about the curve, the non-linear sharpening, then something came up in my mind: maybe the non-linear sharpening would help to avoid halos also, because the sharpening amount would be loewr in the dark and bright areas with high contrast where the halos are more pronounced after sharpen...

another interesting solution would be to make the CONSERVATIVE checkbox to be a curve instead of linear. the conservative option already decreases the amount of sharpening, so if it can be logaritmic instead of linear it will solve.

hello, Vlad, based on your idea, I developed three curves for sharpening, please take a look: luminance value x sharpening amount (percentage), three tables: (...) = from 73 to 183 in luminance 000 = 000% - 000% - 000% - 008 = 000% - 000% - 000% - 016 = 025% - 016% - 012% - 024 = 050% - 033% - 025% ...

Interesting idea, Vlad, the non-linear sharpening would be awesome! an option to change linear/non-linear with a checkbox or a slider (a slider would change the non-linear curve), or one checkbox/slider for shadows one checkbox/slider for highlights, separately... you decide. so user can chose for a...

thanks, Vlad, your comments will be much appreciated. I uploaded the noise presets with the sharpening settings which I use for Canon DSLR, two presets. In these presets the highlight and shadows shows less clipping/crushing because the amount of sharpening is small, but with a careful look you can ...

OK, Vlad, I prepared a project, and also more tests, please read below: I perceived that the issue happens to the shadows dark areas also, in the opposite way. when doing sharpening the dark areas gets more dark, so there are two issues, highlights gets more bright and shadows gets more dark. The te...

Highlight Preservation when doing sharpening

I perceived that when increasing the sharpening in neatvideo the highlights clips. I measured a part of the image which was at 247 value and after sharpening is become 255. So after sharpening there is the loss of some highlight textures and unwanted clipping in the signal in the bright areas. I per...

3 noise patterns for same video

would be great to allow the user to set three squares to pickup the noise pattern in the first neatvideo window because sometimes there are different noise in different regions of the frame. the dslr and mirrorless cameras shows a fine noise where there is more light and shows a mid/gross noise wher...

diagonal lines or free form noise sample box

lots of times the objects in the footage are not in vertical or horizontal aligned position. If I try to draw the square to get the noise sample, the square cannot be big enough, just keep in yellow color. If I could draw a diagonal lines shape I could get a much more biger area and probably it woul...

a way to predict

I did some math calculation to try to predict the GPUs performance in this topic:

I was trying to predict the benefits from the new GTX650ti and I found some interesting results.

some prediction

In another topic in this forum I found the neatvideo benchmark results for gtx560ti (5.15fps) and for gtx570 (6.49fps). So I did a research in nvidia website to find their specifications. After some calculation, I found the difference in performance between them in neatvideo is higher than just the ...

Whatis more important in GPU Cuda Cores or Memory Bandwidht?

Today I have a GT240 which does not improve NV performance anyway. In my researches I found the GTX660 the best price performance GPU. But my current PSU is not powerful enough for it and change the PSU will be expensive, so I started to consider the new GTX650Ti I read here in the forum the GTX560T...
