Warp Affine: custom post processing on pgie for face alignment

Accelerated Computing Intelligent Video Analytics DeepStream SDK

I have OpenCV code to warp the face images (which is in obj_meta) in deep stream.

Can nvdspreprocess be used to do warp affine operations on obj_meta data?

    tfm = cv2.getAffineTransform(src_pts[0:3], ref_pts[0:3])
    face_img = cv2.warpAffine(src_img, tfm, (crop_size[0], crop_size[1]))

Please provide complete information as applicable to your setup.

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

Could you describe the specific processing requirements for the images?
