SK-TDA4VM: pre&post-processing steps in SK-TDA4VM

Hi,

Please refer out edgeai_gst_apps github repos where we have rich amount of documentation available for custom post processing.

Sharing link here : https://github.com/TexasInstruments/edgeai-gst-apps-6d-pose

Pre processing nodes are used in edge_ai_apps source code which is part of sdk, we recommend to go through the source code if you want to explore more on it.

The models which are part of model_zoo are optimized for target, you can learn more about model optimization tools here : https://github.com/TexasInstruments/edgeai-tidl-tools

I want preprocessing steps like image conversion(hwc,float32,reverse) before inference and post processing steps during model outputs(like which format like float value to int)

Hi,

We will get back to you on this issue by Monday.

Pratik

I Would like to know if preprocessing and processing as shown an example below

pre-processing->

• Transpose from CHW to HWC
• Convert from YUV to RGB Convert from YUV/RGB/BGR to Grayscale
• Resize
• Cast to fp16
• Normalisation
• Memory copy
• Crop

post-processing->

• Transpose from HWC to CHW
• Softmax
• Cast fp16 and fp32
• Memory copy
• Argmin and Argmax

If anything like this on SK-TDA4VM plz let me know

Hi,

You can check the list of optimized kernels that we support as part of TIDL.

For example, Normalization, Softmax, Resize etc

Link :  https://github.com/TexasInstruments/edgeai-tidl-tools/blob/master/docs/supported_ops_rts_versions.md

You can refer to tidl user guide for more information, here https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_06_01_03/exports/docs/tidl_j721e_08_06_00_10/ti_dl/docs/user_guide_html/index.html

Note : These operators/kernals are available as part of rtos sdk offering.
