Bone is a hierarchically structured composite material which, in addition to its obvious biological value, has been well studied by the materials engineering community because of its unique structure and mechanical properties. This article will review the existing bone literature, with emphasis on the prevailing theories regarding bone formation and structure, which lay the groundwork for propo...

This paper investigates segmentation based interest points for matching and recognition. We propose two simple methods for extracting features from the segmentation maps, which focus on the boundaries and centres of the gravity of the segments. In addition, this can be considered a novel approach for evaluating unsupervised image segmentation algorithms. Former evaluations aim at estimating seg...

This paper proposes an algorithm that automatically reads license plate from videos that has taken from personal devices. Unlike commonly used license plate reader in toll payment or road control system, video from personal devices usually has more variation in viewing angle, resolution, shutter speed and so on. This work read single frame from video first, then extract the license plate by det...

This paper presents the work performed in the context of the VIMANCO ESA project. It has the objective of improving the autonomy, safety and robustness of robotics system using vision. The approach we propose is based on an up-to-date recognition and 3D tracking method that allows to determine if a known object is visible on only one image, to compute its pose and to track it in real time along...

We participate in two tasks of TRECVID 2009: high-level feature extraction (HLFE) and search. This paper presents our approaches and results in the two tasks. In HLFE task, we mainly focus on exploring the effective feature representation, data imbalance learning and fusion between different data sets. In feature representation, we adopt five basic visual features and six keypoint-based BoW fea...
