This paper presents a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene. Accurately and stably detecting corners is needed for good matching, even for image with rotation and noise. As a well known excellent corner detection method, Harris' technique(More)
This article first systematically classified the uncertainty and provided the multi-scale fractional ordered association model in accordance with the multiple uncertainty time series. From the mathematical point of view, the model used in this thesis extended the integerorder correlation measurement to the fractional-order correlation measurement; elongate(More)
In order to improve the correlation accuracy of correlation algorithm, the fractional order correlation algorithm of uncertain time sequences is proposed in this paper. By taking advantage of the memory property of fractional order, the algorithm introduces the measurement of fractional order differential for the local trend of time sequence into the(More)
In order to improve the correlation accuracy of correlation algorithm, the fractional order relative correlation algorithm of uncertain time sequences is proposed in this paper. By taking advantage of the memory property of fractional order, the algorithm introduces the measurement of fractional order differential for the local trend of time sequence into(More)
This article used fractional order in time series' correlation, and provided fractional order correlation decision model. From the mathematical point of view, the model used in this paper extended the integer-order correlation measurement to the fractional-order correlation measurement; elongated the information recognition from point to line, and rolled(More)
Texture and edge information are equally important to identification of most of natural images. In view of the weakness of the existing integer order differential operators that it can't extract texture information from the images, this study developed a fractional differential algorithm, which can extract texture and marginal information simultaneously,(More)
