This document discusses object detection techniques for images. It begins with an introduction to image processing and object detection. Object detection aims to find instances of real-world objects in images and is used in applications like surveillance and automotive safety. The document then reviews several papers on related topics, including object removal from videos, visual surveillance systems for tracking targets, and augmented reality object compositing. It proposes using skull detection and region growing techniques to detect particular objects while removing shadows and other background objects for improved detection. Region growing would detect the object, while skull detection removes it from the image to analyze the object separately. In summary, the document reviews object detection methods and proposes a hybrid approach using skull detection and region growing.
