Object Detection is a common Computer Vision problem which deals with identifying and locating object of certain classes in the image. I started from this excellent Dat Tran art i cle to explore the real-time object detection challenge, leading me to study python multiprocessing library to increase FPS with the Adrian Rosebrock’s website.To go further and in order to enhance portability, I wanted to integrate my project into a Docker container. If you watched the video you can see that the picture of the IP camera is much sharper however there is a bit of lagging in the video. Object detection is probably the most profound aspect of computer vision due the number practical use cases. All required funtions are ready now to perform the object detection on the browser. Fortunately OpenCV supports IP camera streams out of the box in the usual way we open video streams: You just have to provide a URL to the video stream broadcasted over the network by the IP camera, the user name and the password and that’s it. Please don’t use this example in production without finding a secure way of accessing your camera via the network.Have a look at SSL based protocols like rtsps or https. We have 3 files inside: voc-bird.names : The name of the object; yolov3_10000.weights : The weights we use as our detection model. An image is a single frame that captures a single-static instance of a naturally occurring event .On the other hand, a video contains many instances of static images displayed in one second, inducing the effect of viewing a naturally occurring event. We can obtain knowledge about this theme here.
