High Pass Sharpening / Contrast Enhancement

I'm still very new to coding so I feel more comfortable keeping this stuff separate in case I have to make some major changes. The gaussian shader is a port of Boulotaur2024's shader so most of the work for that was already done.

The Clarity shader is pretty simple though, I don't think there is much more I need to do to it. There are just a few more things I can think of that I'd like to change and maybe after that I'll see if they would want to add it to the Framework.

ioFX v1.1 for ReShade + Framework is a great addition, thank you Ioxa!

Updated ioFX to version 1.2
Download ioFX v1.2 for ReShade + Framework

In this version I added a Bilateral filter and made a few more changes to the Clarity and High Pass Sharpening shaders.

The Bilateral filter can be used to blur without blurring across edges, this is similar to surface blurring. I'm also experimenting with using it for sharpening. The advantage of using a bilateral filter to sharpen is that it won't create halos around the edges of objects. On top of this I've also added a selective sharpening setting to limit the sharpening to highly textured areas, the idea behind this is to eliminate unwanted noise that may show up in areas such as sky textures that don't need to be sharpened.

For the Clarity and High Pass Sharpening shaders I added a setting for MaskContrast. Setting this to 0.00 uses linear interpolation to create the mask, this is what I've been using up till now. Setting it to 1.00 uses the Vivid Light blend mode to create the mask. Everything between 0.00 and 1.00 is a blend between the two.

I also removed the ClarityRadius setting and changed the way ClarityOffset works. As the offset gets larger the shader will increase the number of passes used, this seems to have a much lower performance cost than doing a single pass with a lot of texture fetches.

I still have a lot of ideas and things I want to work on but I'm not that motivated to work on it right now so I'm uploading what I've got. Let me know if you think any of the changes are bad or if I've broken anything and I'll try to make adjustments and improvements.

Could these shaders be merged to reshade repository?

Ioxa,
You forgot a line #include EFFECT(ioFX, Util) in readme

I'm having some flashes across the screen especially when used BilateralFilter are as asterisks or as the number sign, like a rain.

On the other hand all this part seems not to work, maybe this doing something wrong
#define CurveRed 0.00 //[-0.50:0.50] //-
#define CurveBlue 0.00 //[-0.50:0.50] //-
#define CurveGreen 0.00 //[-0.50:0.50] //-
Thanks

It could be caused by something in the blur passes, that's the only thing I can think of that would create that pattern. I haven't noticed anything like that though, so if you could post a screen shot and your settings I might be able to figure out what is causing it.

I forgot about those curve settings... I didn't update the color filter shader, they won't do anything.

they are like crosses and asterisks and are on the whole panatalla

It seems like you finally burned yor GPU memory. Congrats. You are a man now

Jokes aside if it looks similar to the pics in the link below your card may be gone. It may only happen in certain situations because the rest of the time you are not using the damaged area of the memory.

Hi, thanks for your answer, but I doubt that this is the problem because when I disable the function reshade stop doing it, plus the video card is new has no more than 5 months and is an AMD Asus Strix R9 fury.
thanks

I haven't been able to reproduce the problem but I see a few possible causes. The multiply blend mode is the original image * the sharp/clarity mask * 2.0, so the brighter parts of the image get a lot brighter. The detail strength in the bilateral filter is the detail channel * detail strength, since you have the setting at 1.90 the bright parts are again getting a lot brighter. My guess is that combining the multiply blend mode in high pass and clarity and then multiplying the detail by 1.90 is causing some issues. Try reducing the detail strength to 1.00 and try some of the other blend modes. If that doesn't get rid of it try enabling each effect one by one to see if you can narrow it down a single shader that is causing the problem.

thank you very much, you can fix by changing these values, thank you very much for your great work

Glad that worked. Thanks for letting me know. Did it seem like it was mostly the bilateral filter causing it?

Hey loxa,

Have been following Reshade and your awesome ioFX almost from the start, but didn't have any questions or the necessity to ask anything, till the arrival of the New Reshade 2.0 and the absence of your ioFX in it, I had to ask if you're working on an update for Reshade 2.0?

I really hope you do, cause I can't use Reshade 2.0 without your awesome ioFX, (still using Reshade 1.1 and eagerly waiting for your update)

Thanks in advance!

Yup, I'm working on porting the shaders to 2.0. I ran into a couple issues but I think I've got them solved, just waiting on clarification on something. Hopefully it won't be more than a day or two.

Awesome! Do take your time. I am sure that am not the only one who's glad to know that you are working on an update.
Thank you again in advance!

Updated the shader files for compatibility with ReShade 2.0 and the new ReShade Assistant.
Download Shaders by Ioxa for ReShade 2.0

I made some small changes to some of the shaders but nothing major. The Clarity shader probably got the biggest change, I once again changed the options for adjusting the width of the effect. I think the way it is set up now gives the most customization for quality and performance. But I'm open to any ideas that may improve it.

I also uploaded a version of the shaders with an updated Gaussian shader. I'm not entirely sure I will keep it the way it is so consider this a test.
Download Shaders by Ioxa for ReShade 2.0 With Gauss

I changed the way the weights and offsets for the blur passes are calculated, this allows for a lot more flexibility when adjusting the blur width.

I added an option called SurfaceBlur which will help reduce halos that may appear around objects. This process used for doing this does not work very well in a separable filter so it causes some artifacts. As long as the blur strength isn't set too high they shouldn't be very noticeable.

I changed the "warm" option is GaussBloomWarmth. I'll never get it to look the way it did in SweetFX so I tried something a little different, I gave it a bit of a yellowish tint with a reddish tint around the edge. I don't know if I'll keep it this way or not, just something I wanted to try out.

I forgot to add a readme to the files but the install should be pretty straight forward. Merge the ReShade folder with your existing ReShade folder and overwrite the files when prompted. This will overwrite Pipeline.cfg, Shaders_by_Ioxa.cfg, Ioxa.undef, and Gaussian.fx if you've downloaded the files with Gauss.

If you have any questions, problems, or suggestions let me know!

I suggest you add those to github.com/crosire/reshade-shaders

many but thank you very much to you and extend to all other

Ok, I'll add them. I want to clean them up a little first and see if anyone has any issues with the ones I posted here.

I think I fixed the cause of the problem you were running into with the bilateral filter. Try the shaders with the settings you were using before and let me know if it's still happening.
