Scale Invariant Feature Transform: A Graphical Parameter Analysis
نویسندگان
چکیده
In this paper we introduce a general purpose graphical processing unit (GPGPU) based method for performing a sweep across a set of the scale invariant feature transform (SIFT) parameters for pairs of images. The focus of the paper is the analysis of the data generated using information visualisation techniques including a cross brushing technique between parallel coordinates, scatter plots and histograms. Results have shown us the importance of carefully selecting some parameters depending upon the properties of an image pair while other parameters are shown to be robust to variation. The parameters chosen by analysis of the sweep data have then been compared to the previously published SIFT’s values and a consistent improvement in accuracy is shown.

متن کاملSiftCU: An Accelerated Cuda Based Implementation of SIFT
Scale Invariant Feature Transform (SIFT) is a popular image feature extraction algorithm. SIFT’s features are invariant to many image related variables including scale and change in viewpoint. Despite its broad capabilities, it is computationally expensive. This characteristic makes it hard for researchers to use SIFT in their works especially in real time application. This is a common problem ...
متن کاملComplex Wavelet Transform Variants in a Scale Invariant Classification of Celiac Disease
In this paper, we present variants of the Dual-Tree Complex Wavelet Transform (DT-CWT) in order to automatically classify endoscopic images with respect to the Marsh classi cation. The feature vectors either consist of the means and standard deviations of the subbands from a DT-CWT variant or of the Weibull parameter of these subbands. To reduce the e ects of di erent distances and perspectives...
