Here is how I installed Tensorflow object-detection (follow the official installation guide): Image building is a bit long and take several minutes. When humans look at images or video, we can recognize and locate objects of interest within a matter of moments. Maybe intentionally decrease the frame rate when reconstructing the video to watch it in slow motion. If you deny access, the program will not be able to find network cameras on your local network. Now let’s step one ahead and do some object detection on videos. Vehicle number plate detection and recognition 3. Part 4 - What to enrich with - what are Data Collections and Analysis Variables? This function updates the CSV file by encoding object detections in the MISB 0903 standard in the vmtilocaldataset column. For our example we will use the ImageAI Python library where with a few lines of code we can apply object detection. Optionally, in a video captured from a drone, we might be interested in counting or tracking individual objects as they move around. Part 3 - Where to enrich - what are Named Statistical Areas? The application dashboards are originally populated with telemetry and properties generated from the IoT Central simulated devices. For this Demo, we will use the same code, but we’ll do a few tweakings. Object localization deals with specifying the location of an object in an image or a video stream, while object identification deals with assigning the object to … Here is the point which takes me some time to resolve (with an unsatisfactory solution). I’m not very satisfied with the solution of using a first python script to initialize the X11 system, but I have not found anything that solves this problem so far. When detecting objects in a video, we are often interested in knowing how many objects are there and what tracks they follow. I also show you how I have adapted the original python script from Dat Tran to perform video processing with multiprocessing. Finally, if output priority queue is not empty, the frame with the highest priority (smallest prior number) is taken (this is the standard priority queue working). Active yesterday. When visualizing the detected objects, the following visual_options can be specified to display scores, labels, the color of the predictions, thickness and font face to show the labels: The example below shows how a trained model can be used to detect objects in a video: The following example shows how the detected objects can be additionally tracked as well as multiplexed. Object detection has applications in many areas of computer vision, including image retrieval and video surveillance. This function applies the model to each frame of the video, and provides the classes and bounding boxes of detected objects in each frame. Well-researched domains of object detection include face detection and pedestrian detection. In addition, I added a video post-proc… frame_rgb = cv2.cvtColor(frame[1], cv2.COLOR_BGR2RGB), # Check output priority queue is not empty, Stop Using Print to Debug in Python. Frames are put into a queue to be processed by a pool of workers (in which Tensorflow object-detection is running). The following options/parameters can be specified in the predict video function by the user: The track=True parameter can be used to track detected objects in the video. We iterate through the list of trackers and detections and assign a tracker to each detection on the basis of IoU scores. As an example, in a video from a traffic camera installed at intersection, we may be interested in counting the number and types of vehicles crossing the intersection.
