The Scale Invariant Feature Transform (SIFT) algorithm is utilized broadly in image registration to improve image qualities. However, the algorithm’s complexity reduces its efficiency in biology study and usually requires real-time. In this article, we present an improved SIFT technique in software architecture for matching sequences of images taken from a line-scanning ophthalmoscope (LSO). The method...
More and more electric power data are generated with the development of the electric power field. Hyponymy relationships extraction is an important task in building semantic knowledge base, information retrieval and other semantic applications etc. This paper uses sentences to match “is a” pattern as research subjects and proposes a novel hyponymy relation extraction approach, which combines lexical...
The camera motion that is caused by the moving camera is one of two types of video motion. The feature-based techniques are known to perform more robust with large motion. The research of such a robust feature-based camera motion estimation method is necessary and possible. In this paper, a robust feature-based camera motion estimation method is proposed. The algorithm uses the motion vectors obtained...
In an ideal radiotherapy procedure, the treatment system would continuously adapt the radiation beam delivery to changes in the tumor position. The development of such a medical image-guided tracking capability is necessary. In this paper, an efficient medical image tracking algorithm based on motion estimation is proposed. The algorithm uses the motion vectors obtained from a set of selected points...
