Hi,
I am working on a pipeline which face detection as primary inference and generate face feature vector as secondary inference. Before the secondary inference, I have a face landmark detector which is added to user-meta-data. I want to align the faces using these landmarks points to feed the sgie.
Presently I am achieving this by changing the(custom plugin dsexample) blur-objects function to align-objects where I change the ROI of faces(in_mat) to aligned faces. But in this case, the original frames are distorted.
Is there a way to define some function which preprocesses the in_mat for the sgie before feeding it.
Any help will be appreciated.

thanks.

this is older topic from https://forums.developer.nvidia.com/c/accelerated-computing/intelligent-video-analytics/deepstream-sdk/15 . Hower, dont have answer yet,

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Sorry! Don’t understand your requirement, What do you mean “define some function”? Why do you think this can solve your issue?
