How to to find location (ROI) of a recognized object in tensorflow

Question

I was using the tensorflow android example which has a placeholder for the location of a ROI (see tensorflow/examples/android/src/.../Classifier.java), but it is not used. I would like to be able to locate the ROI of the classified object. I looked through the code, but it wasn't obvious how the location could be determined. Does tensorflow support this?

Answer 1

Unfortunately that placeholder is not populated, and actually determining the region of interest of an object is still a hard research problem. We don't currently have a released example of a model that can do that in TensorFlow, but if you want to look through the research, the term to look for is 'localization'.
