Ticket Name: RTOS/TDA2: How to feed test video to tidl_OD from camera?

Query Text:
Part Number: TDA2 Tool/software: TI-RTOS Hi TI Team. How to feed test video to tidl_OD from camera? In PROCESSOR_SDK_VISION_03_03_00_00, there is an use case for TI deep learning. It analysis the input data from file and do the object detection. How to change the input data from file to camera? chains_tidlOD.txt UseCase: chains_tidlOD

Hi Hacker Hsu, TI TIDL OD is validated only with pre-trained videos However if you want to use capture from camera make sure it outputs RGB data In attached .c file, comment out inData_OD & inHeader_OD file reading from SD card (actual trained input files for TIDL_OD usecase) Refer below for training CNN network with your dataset github.com/.../caffe-jacinto Regrads Surya
