TF Lite - How to retrieve object location within image?

Special Interest Groups Micro
#1

I have TF Lite working on an ESP32 using the person detection example code from tflite-micro-esp-examples/examples/person_detection at master · espressif/tflite-micro-esp-examples · GitHub

I need to be able to retrieve the person’s location from the tensor output data. I don’t see this data coming back. I only get 2 values back (person_score and no_person_score) in the output data array. Is there a configuration that I can set to enable the 2 data point locations (upper left & lower right) to be sent back within the data array?

You may need to train own model to do that. Person localization is a regression task, however, person detection example shows a binary classification use case.
