Introduction to Multi-Object Tracking (MOT)
Multi-Object Tracking (MOT) is an essential task in computer vision that involves tracking multiple objects in both recorded videos and real-time live-streaming scenarios. As a longstanding goal in computer vision and machine learning, MOT is becoming increasingly important and widely applied in various fields, including autonomous driving, traffic monitoring and flow counting, and many more. MOT plays a crucial role in autonomous driving. Its primary function involves tracking the trajectories… Read article
Non-Maximum Suppression in PyTorch: How to Select the Correct Bounding Box
In certain scenarios, object detection algorithms such as YOLO, Faster R-CNN, and SSD may generate redundant and overlapping bounding boxes. Therefore, to ensure accurate detection results and retain only the most confident ones, it is crucial to implement a mechanism capable of identifying and selecting the most appropriate bounding boxes while discarding the overlapping ones. To achieve this objective, we can use a method called Non-Maximum Suppression (NMS), a post-processing… Read article

A Simple Guide to Making Transparent Overlay Labels on Object Detection
If you wish to add transparent overlay labels to your detected bounding boxes without covering the underlying image, using transparent text overlay can be a great solution. A transparent text overlay is a text that is overlaid on top of an image with a partially transparent background, allowing the underlying image to show through. To create transparent overlay labels, we can use a technique known as alpha blending. Alpha blending… Read article
