dc.description.abstract | Extracting foregrounds from complex outdoor backgrounds in the temporal domain presents a significant challenge in object recognition. The primary reason is the changes in luminance observed in the moving foregrounds of video frames and the dynamic background leading to loss of minute changes undergone by foreground objects. This compromises the accuracy of object identification patterns and can lead to misclassifications in detection and recognition. These difficulties hinder the automatic analysis and effective classification of computer vision systems in real-world scenarios, making manual performance costly. Work has been done to address these challenges by employing computational geometry to estimate descriptive features of objects within images. In this thesis, we extend this notion by proposing an approach to estimating shape descriptors (features) in the temporal domain of moving foregrounds by analyzing shape's topological space properties for video processing. To achieve this, we introduce the concept of optical vortex nerves, which will be applied to various moving object videos. By constructing vortex nerves using vertex termed 0-simplices, edges termed 1-simplices, and triangles termed 2-simplices in the foregrounds, we can derive shape-based spatial-temporal descriptor sets for each moving object. Moreover, I then employed the shape descriptor sets for shape matching to assess the descriptive proximity between various vehicles and establish their descriptive nearness (similarity) for recognition. This practical implementation serves as an embodiment of the aforementioned concepts discussed throughout this document. | |
