You don't understand DNN. After you have saved a "pattern", you expect that "pattern" will be found again immediately in the same image. This is how the old algorithm worked. DNN means learning, learning like children... Give the engine more images of Megan and she will recognize the other image. I have 2 young girls here, they were often confused even in real life. DNN is always 99% correct for a wide variety of images. Maik You can also try reducing the initial accuracy 45-60. Maik Git commit 9d60f152e77b5201ce6bf23473684a32444bf586 by Maik Qualmann.

Created attachment 124903 [details] Sample picture SUMMARY A face is not dectected on a duplicated picture while I identified it on the main picture. STEPS TO REPRODUCE 1. Start from a cleaned DNN database Download the picture enclosed. Duplicate it. Scan for faces. See attached screen capture for normal detection results in people view. 2. Identify one face (Megan here). See attached screen capture. 3. Re-launch the recognition process (only to that directories) OBSERVED RESULT The other identical face of Megan is detected but NOT recognized (it remains empty/unkown). EXPECTED RESULT DNN should easily recognize the same face on the same duplicated picture !
