Perhaps it is still clear in historical ink how the story of Timor Leste was when it separated from Indonesia after the referendum conducted under the UN agreement between Indonesia and Portugal on 30 August 1999.

This is also the case with Papua. Under the shadow of the Free Papua Organization (OPM) movement, the motives for independence from Indonesia continue to emerge. At its peak, separatist movements of this kind cause chaos that can lead to civil war. Apart from the sharp bu...

I am looking to hire a freelancer to help me create an Android app using OpenVINO format models. The OPENVINO models are basically what I got from the below repo- The above code uses two OPENVINO models- face detection and spoof detection. Once we pass an image or a video using a webcam, it creates a bounding box around the detected face and labels it as real/fake. I have tested the above code and it's working as expected. Now I need a simple android app integrated with the models as mentioned in the above code link. With this app, once a user will open the front camera, models should work and detect as they are working.
