Help understanding Refine Edge using Select and Mask

So, below is before and after refinement using Color Aware/Object Aware (Do not know which one it is, since I'm backtracking through scriptlistener). Radius of 4 px is selected in Edge Detection, and Smart Radius, Decontamination are off.

 

I need to understand what exactly happened. I do not understand edge refinement at all, or how my left pixelized binary image turned into the non-binary image on the right. Help, please?

Can you show us what you are trying to select?

And explain in more detail what we are looking at in your screen shots above?

I have no more idea than mj what is going on here.

The image on the left is a mask. The white pixels represent the pixels where my original color will later be present. However, the binary mask on the left has to be converted into the grayscale mask on right.

Hi,

So the way I understand this is you've taken a mask and applied a refine edge to it?

 

I'm trying to work out why you'd do that. Can you help us understand?

 

Select and Mask is for perfecting selections.

 

Also, what do you mean by binary mask?

 

This resource might help. https://helpx.adobe.com/photoshop/using/select-mask.html

Hi @Azzam Masood ,

 

Your original image (left) looks like a 1-bit image.

 

Can you help us understand what your trying to do?

 

Are you trying to select all the black pixels for example?

 

Best

Hello. I'm trying to select all white pixels, and then refine the edges is what I think is happening in the right image.
