Thanks for the reply @Jason. I couldn’t get it to work by calling the data method on the result directly as this gave me an error but it worked, when calling it on the individual results:
let boxes = Array.from(await result["TFLite_Detection_PostProcess"].data());
let classes = Array.from(await result["TFLite_Detection_PostProcess:1"].data())
let scores = Array.from(await result["TFLite_Detection_PostProcess:2"].data())
let n = Array.from(await result["TFLite_Detection_PostProcess:3"].data())

The complete code is available on my Github 3. If you find anything that can be improved please let me know.
Kind regards,
Gilbert Tanner
