Hi Deepstream Team! I am doing a custom preprocessing algorithm on the cropped images before SGIE which is face alignment. Therefore, I decided to follow the dsexample to get the Image from GPU(using get_converted_mat, NvBufSurfaceSyncForCpu …) and have done that. After the face alignment, I have 1…

For the example on comment 2, you can do your custom preprocess by installing a probe. And if you want to do it in dsexample, you can refer the NVIDIA DeepStream SDK Developer Guide — DeepStream 6.1.1 Release documentation , it,s an inverse process of get_converted_mat

Hi @ledaiduongvnth I am indeed interested in the application that you mention.
I have replied to a post on the same topic some time ago. I have not figured it out how to solve my problem yet.

Thanks in advance!
