Key Point Detection and High Speed Image Registration Using BLoG

SIFT is one of the feature region extraction methods. It is widely used in various fields including object recognition, mosaic object tracking, etc. However, since SIFT requires lots of arithmetic operations, it is not appropriate for real-time use. Therefore, many researchers has been tried to prepare other measures. SIFT using PCA or SURF is one of them. This paper is to study about the real-time CCTV combined system using the local partial image and to suggest the combination and recognition method for frames. Its purpose is to reduce the combination speed of the suggested algorithm compared to the existing one and to enhance the overall recognition rate according to this. Since the existing SIFT algorithm method has a patent and a slow processing speed, in this paper the improved local image regenerating method was used and the speed was raised according to the actual CCTV processing speed. Based on the recognition rate and speed by using the localized image, this paper consisted of realization of overall system and introduction of algorithm, and the comparative evaluation of performance was carried out through the actual experiment. By applying the CCTV operating in real time, the low-cost system was built with Inline System not with each image and this could reduce the physical fatigue of watcher, have an economic effect and could be used by general users easily.
