TDA4VM: Reading the data into CV:Mat format from TIDL -RT inference engine binary output file

Part Number: TDA4VM

HI Team,

we are working on NN model and able to generate binary file.

Import traces:

As we are using tidl-RT executioner to get output is of binary file (.bin) extension.

what format will this data be stored in the binary...?

Is there supported ways you can suggest to read these binary inference output (.bin) into Opencv to read data in some matrix for example cv::mat format...?

For example :

cv::Mat inputBlob = cv::dnn::blobFromImage(img, 1.0, cv::Size(mInputWidth, mInputHeight), cv::Scalar(0, 0,
        // 0), false);

This is a blocker and high priority for us...!

Kindly do the needful in this regard.

Thanks & Regards,

Pawamana Tanjore.
