Description

opencv_dnn.blobFromImages method supports multiple pictures inference at the same time. Is it necessary to put at least two pictures? I found that when I put in only one picture, I didn't get the result I wanted. It's OK to put in more than one picture.

Contributor guide

Research direction
Investigate the behavior of `opencv dnn.blobFromImages` with a single image versus multiple images. Check the OpenCV documentation and source code for any constraints on the number of images. Compare the output arrays for single and multiple inputs to identify differences.
