understanding this metric

[nanmehta]

can you please help me to know, why you have used three images in test.py and concatenated the image1 with image 1 and image2 with image3?
please help me I am new to this field

hello,
The model expects two image at a time to compute distance metric(lpips).
To compute multiple (2 in test.py case) distance metric, I just used concatenation for batch process.

• distance between image1 and image2
• distance between image1 and image3
