Abstract: In this thesis, we propose a general framework for building object-aware image understanding systems. This unified framework integrates the recent object localization, feature description and data mining techniques. The proposed framework aims to solve the Web image recognition problem given concerned topics. Firstly according to the system requirement, related photos and videos are crawled from the Internet. Then the data are screened and indexed using the object detectors learned from annotated data subsets. Thereafter, the collected datasets are further analysed to obtain the fine details of the objects and object attributes in the images. Comprehensive object description is obtained using image descriptors extracted from key parts of the detected objects. Such object-aware image description is proved to be more effective than traditional global image description in understanding image contents. Core techniques including image feature representation, object detection and object attribute description are thoroughly investigated and implemented.
