    Hi

    i want one question i am referring the semantic segmentation usecase and there are four file

    1.semantic segmentation text file

    2.priv.c and priv.h semantic segmentation usecase 

    what happen in the priv.c and priv.h and also source code

    please tell me 

    Thanks & Regards

    Hi Reshma,

    when you create new usecase, you create the .txt file (for example chains_semSeg.txt) containing the structure of the usecase (how the links are connected in a chain).

    Then you run UsecaseGen tool, which based on the .txt file creates the XXX_priv.c and XXX_priv.h files. They contain initialization of Link IDs, setting the link pramaters to default values, adding IPC In/Out links where need and some other chain configurations. In general, you wouln'd need to modify _priv files.

    To get a clear idea of how usecase is created and what particular usecase files are for, please check vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_UserGuide_UsecaseGen.pdf

    Regards,

    Yordan

    In semantic segmentation source what parameters are Present what is the working of semseg.c file

    Please tell me

    Hi Reshma,

    the semantic segmentation usecase is started by Chains_semSeg() function in vision_sdk/apps/src/rtos/usecases/semSeg/chains_semSeg.c.

    This function configure, creates, link various links to establish the usecase. Further in a while loop displays run time menu and waits for user inputs to print the statistics or to end the demo. Once the user inputs end of demo stop and delete functions are executed.

    You can look at it and see which functions it cals or you can try to step in line by line while debugging it with Code Composer Studio.

    Regards,

    Yordan
