#WinML – How to create a #Windows10 App using #YOLO for object detection (4 of 4)

Windows 10 and YOLOV2 for Object Detection Series


Let me start from my previous post where I already coded a a real-time video camera feed process using with Tiny-YoloV2. The model returns results in a 416×416 size image, and that’s why the detected frame with the person looks kind of weird.


It’s not complicated to work with the output so it can be adapted to the size of the Webcam control, only a couple of lines of code.

And in this way, we can draw the frames with the right format. In the following image it is possible to see how a person is detected, with a low precision score and as well as one of the pictures on the wall it is detected as a monitor.


From here, it’s all about optimization, for example, take the value of the webcam control only when the app is resized.

In the final example, I have also added a visual indicator as a status bar, which shows the number of frames processed per second and the real size of the elements in the App.


The full code for the example can be downloaded from


Happy Coding!
