How to run ai_analysis_faces?

[hoonkai]

Hi all I'm having trouble running ai_analysis_barcode and ai_analysis_faces. I've tried running both ai_analysis_faces and ai_analysis_barcode.dart but only a camera preview screen is shown and there's no response when given a face or a barcode. With ai_analysis_faces, analyzeImage doesn't seem to be run.

Does anyone know how these are meant to be invoked?

Thanks

Hi, You should make a try with a real device. I doubt it works on simulator.

I have but to no avail:

Tapping the capture button just takes and saves a photo.

Here's the log:

I think the onImageListener of the analysisController isn't being triggered. If my take is correct, AnalysisController sets the listener for the image stream, but start() isn't invoked.

Hi we're looking at this. 👌

Hi @hoonkai You were right, we missed a start() call. It should be fixed on master now 👍 Also note that the capture button is just there to take pictures, it doesn't involve image analysis in this example. :)
