    Hi, We have a small sales team of 6 people. We provide them company android phone devices so they can make calls and chat with the customers. We are requiring an android app so we can install in the company devices, with the required consent of course, so the apps will help us to monitor how many calls the sale team made, which customers were contact, calls logs, call recordings, etc. Since we don't want to ask every time for the devices, we need the app to sync automatically with any cloud service like OneDrive, Google Drive, Firebase, etc. so the manager can access the data and make the requerid reports and required monitoring.

    The goal is to complete Yolov5 image segmentation inferences in Java. So far, I am using OnnxRuntime to send the image tensor to the model and receive the inference tensors. However, the functions used for converting the output tensors to masks are more challenging and need to be completed. We need to convert the following python functions to Java: non_max_suppression process_mask The job is successful once we can apply non_max_suppression and process_mask to our arrays/tensors in Java. However, there should not be any significant differences in speed between the Python and Java Implementations. Please send a proposal if you have strong experience with numpy/pytorch, tensors, arrays, ONNX and feel you can complete the job AFTER looking at the two Python functions displayed above.
