The video tutorial discusses the YOLO object detection algorithm, starting with its prerequisites and limitations of previous architectures. It revisits image classification, explaining the process and challenges, especially when dealing with varying image sizes. The tutorial then delves into the more complex problem of object detection and localization, highlighting the difficulties of handling multiple and overlapping objects. The video concludes with a preview of future topics, including techniques like the sliding window and how convolutional neural networks can enhance object detection.
