The traditional computer vision approaches were in the game until 2010,.

In the history of object detection, there have been two distinct eras:

And of course, all of this wouldn’t have been possible without the power of Deep Neural Networks and the massive compute by NVIDIA GPUs. Nevertheless, the progress in this domain has been significant every year, the research community achieves a new state-of-the-art benchmark. Object detection is one of the most critical and challenging problems in computer vision, and it has created a history in the past decade with its development. Many other challenges are associated with object detection like occlusion, deformation, viewpoint variation, illumination conditions, and essential speed for real-time detection (required in many industrial applications). In certain cases like this one, when an image depicts a single object, classification is enough to answer our question.įigure 6: Many negative background examples and few positive foreground examples ( source). As shown in Figure 1, we have a Santa Claus and a few more objects, but the main object is Santa which is correctly classified with 98% probability. Generally, we deal with scenarios where only one object is present in the image classification. Recall in Image Classification the goal is to answer the question of “what is present in the image?” where the model attempts to comprehend the entire image by assigning the image with a specific label. To learn how the YOLO family evolved with each variant different and better than the previous version in detecting objects in images, just keep reading.

The third one is Single-Stage Deep Learning based algorithmsĪnd today, we are going to discuss the YOLO object detection family, which falls under the Single-Stage Deep Learning algorithms.Two-Stage Deep Learning based algorithms.There are three classes of algorithms in object detection: But to understand the magic behind these current best architectures, it is necessary to know how it all started and how far we have reached in the YOLO family. Since its inception, the object detection field has grown significantly, and the state-of-the-art architectures generalize pretty well on various test datasets. And today, we will give an introduction to the YOLO family by covering all the YOLO variants (e.g., YOLOv1, YOLOv2,…, YOLOX, YOLOR). YOLO (You Only Look Once) is a single-stage object detector introduced to achieve both goals (i.e., speed and accuracy). Hence, choosing an Object Detector that fits the bill for both speed and accuracy becomes essential. Many use cases, especially autonomous driving, require high accuracy and real-time inference speed.

It is one such field that is not just limited to academia but has a potential real-world business use case in domains like video surveillance, healthcare, in-vehicle sensing, and autonomous driving. Most computer vision problems involve detecting visual object categories like pedestrians, cars, buses, faces, etc. Object detection is one of the most crucial subjects in computer vision.
