Question about Omega.

[EternalKingdom]

I appreciate you for sharing your work to public and your dedication.
Thanks to you, i could learn more about example-based image synthesize.

During the code study, i found calculation of the Omega in the patch matching.
Which was the concept that i could not find from patch match algorithm (PatchMatch: A Randomized Correspondence Algorithm for Structural Image Editing).
Can i know the concept of Omega. And if reference of that concept is exist, can i know the reference(paper)?

I look forward to your reply and thank you again.

I found similar concept of the Omega from Fiser's stylit paper.

It refers like this.

This EM-like iteration approach produces notably better results, but it frequently leads to the wash-out effect. Kaspar et al. and Jamriska et al. mitigate this problem by encouraging uniform source patch usage.

Exactly same concept mentioned at Self Tuning Texture Optimization paper.
At section 3.2 as spatial uniformity.
