Hello Nvidia, I have a question. Does nvdspreprocess plugin support preparing multiple tensors based on detected objects metadata generated on the fly (Or implementating through “custom-tensor-preparation-function” interface is possible). I want to apply some transform (perspective transform) and feed the prepared multiple tensors to the downstream nvinfer component based on metadata generated by upstream nvinfer components.
Thanks and sorry for bad English :D

Seems you need pgie and sgie nvinfer plugin. nvinfer plugin is open source. You can do any process.

Hi, what I’m asking is if implementing nvdspreprocess with variable number of tensors through “custom-tensor-preparation-function” interface without modifying plugin source code is possible. Thanks

any advice?

Seems yes.
