What does it mean to use ImageJ?
Is there any video or tutorial showing what you mean?

Re: Frequency Separation without the Contrast Grou
If you some use more sophisticated blurring than Gaussian Blur then most of the issues are resolved.
You can try Surface Blur or follow Nino Batista's method:

Re: How to get this highcontrast, sharpened look?
Hi,
Nothing can sharpen as Multi Scale Sharpening.
When you use the Multi Scale approach you have all the data of the image at the end of your fingers.
You can read about it here:

There's another "Multi Scale" plug in at the Adobe Exchange named: Fixel Detailizer 2 PS:

Re: The Math Behind Photoshop's Unsharp Mask and G
Regarding your question, I have math background mainly with MALTAB programming skills.
Now my problem mainly deals with how does Photoshop translates the user's Radius parameter into the size of the Gaussian Blur Filter and...

Re: The Math Behind Photoshop's Unsharp Mask and G
Klev,
I really don't understand you.
I showed you how Adobe Photoshop creates USM using Gaussian Blur.
The way I showed is 100% identical (Put it on difference mode and see everything is zero).
Now, if no...

Re: The Math Behind Photoshop's Unsharp Mask and G
Hi,
Photoshop doesn't allow Subtract and Add in 32 Bit mode.
So, If I have the photos in MATLAB, how should recreate this?
Should I clip into [0, 255] / [0, 1] after each subtraction / addition?
It...

Re: The Math Behind Photoshop's Unsharp Mask and G
Klev,
I was wrong with the formula.
It's M = 2 * ceil(Radius).
You have at least 3 sigma as radius, the Gaussian is practically 0 outside it.
Though probability they use IIR filter for that.

Re: The Math Behind Photoshop's Unsharp Mask and G
Ok,
I think I'm getting close.
Using Photoshop's GB Impulse Response I think I have something close to how Photoshop's Gaussian Blur is working.
The size of the filter is M X M where M = ceil(radius)....

Re: The Math Behind Photoshop's Unsharp Mask and G
I'm just trying to implement Gaussian Blur and USM as close as possible to Photoshop.

The Math Behind Photoshop's Unsharp Mask and Gauss
Hello,
Has anyone succeeded in reproducing Photoshop's Gaussian Blur and Unsharp Mask?
I have a technique to apply a really nice Local contrast Enhancer based on Unsharp Mask yet I have to reproduce Photoshop's first.
I reproduce Photoshop's Unsharp Mask using some math...

How could you make the Script a Binary File?
Thanks....
