TDA2: Classification model on TDA2X

Navin Prashath

Part Number: TDA2

Hi,

I am trying to run the classification model using object detection usecase. I replaced the NET_OD.BIN and PRM_OD.BIN with classification network and parameter. Based on the classification output from the model, I will change the position of box being drawn on the image.

I am getting the pointer to the output of softmax buffer on ObjectDrawPlugin as follows:

metaDataAddr = pCompositeBuffer->bufAddr[0][1]; //ChId 0 contains the image.

bufferOffset = ((44+8)*4) + 4; // Due to the padding of 4 on the borders

classPtr = ((UInt8 *)((char *)metaDataAddr)) + bufferOffset;

But the classid I'm getting is not proper. How to get the classification output at the next layer?

When I tried to run the model using TIDL FILE IO Usecase it dumped 2304 bytes instead of 44bytes(44 class model).

Hi,

Are you getting proper Classid in the standalone setup? If not first we will try to fix this issue in the standalone.

Thanks,

Hi Praveen,

I was able to run in the standalone mode in TIDL and the output dumped was proper. I am getting correct classid and only 44 bytes have been dumped.

Hi Navinprashath,

If you are getting proper output on standalone and not in VSDK, then I need to check this issue with VSDK team.
Meanwhile can you check if you can see these 44 bytes of proper output anywhere in the VSDK dumped 2304 bytes.

Thanks,
Praveen

Hi Praveen,

I am able to resolve the issue in TIDL OD usecase. It seems to be a buffer handling issue from my side. I will check in TIDL FILE I/O usecase once again and update here.
