How to find two or more similar PSD files in the same directory? and list the filenames for select and delete . Software example: Visipics. (Note: PSD files are multi-channels)

or IN Br, Some method can help me to do it ?

It isn't clear what criteria would be used to compare images.

Analyze and compare the number of channels, then take the value according to a single channel, and then use the Perceptual Hashing algorithm (Perceptual Hashing) to calculate the similarity of each channel image. Then sort by proximity and display thumbnails.I don't know if such an idea is okay?

Please explain what you mean with the help of screenshots or sketches tha clarify the layer/channel structure. 

I am not aware of any implementation of perceptual hashing in Photoshop that could be used in Scripting. 

Photoshop is an image editor (not an image organizer), so the »primary« approach would seem to be stacking images and calculating differenes, which would in all probability be hugely time-intensive and therefore »barely« to »not« useful. 

I wonder if Bridge or Lightroom might offer something more efficient.

Something similar to what is available in the Photoshop Elements Organizer ?
