TDA2PXEVM: Function to extract the masks from semseg usecase

Hafiz Muhammad Owais said:

1. How to use vlib within the tidl_postproclink,c?

I can't find the file tidl_posproclink.c in the SDK.  Is there a typo?

Also, not sure I understand the question.  Assuming that this link is running on DSP, then adding vlib call is like adding any other library call.  You need to call into the function you want, and make sure that the header file vlib.h is included and the makefile includes the include path for this.

2. Which function of vlib can be used to extract the information of individual class mask. What I am looking for is something similar to cv2.inRange function in Vlib?

There is none in vlib.

3. Is there any function to find the contours as well in vlib?

There is none in vlib.

Hi Owals,

Unfortunately, no we don’t have such function that would analyze the output of semantic segmentation. However you can train another deep learning network that would analyze the output of the semantic segmentation and detect regions in which there is a person sitting on a bike. Or the original semantic segmentation model could be retrained to detect 4 classes: bicvcle alone,  person alone, person sit on bicycle, background.
