Scalable Image Indexing and Retrieval using Wavelets
With the development of world wide web and fast computer technology, the use of visual information has become a routine in scientiic and commercial applications. Images and videos are being captured and archived in large databases and it is extremely important to develop eecient technologies to process, manipulate, and search large visual information archives. In this context, retrieving images...
متن کاملImage Decomposition and Tracking with Gabor Wavelets
This paper explores the use of the Gabor wavelet representation of an image for robust object tracking in robot vision (object grasping, gesture recognition and face tracking in human-robot interaction). For image decomposition we developed a fast non-iterative transform algorithm, in which the original image is processed with a 2D Gabor wavelet filter bank. We used the positions of the local e...
متن کاملModified Gabor Wavelets for Image Decomposition and Perfect Reconstruction
This article presents a scheme for image decomposition and perfect reconstruction based on Gabor wavelets. Gabor functions have been used extensively in areas related to the human visual system due to their localization in space and bandlimited properties. However, since the standard two-sided Gabor functions are not orthogonal and lead to nearly singular Gabor matrices, they have been used in ...
متن کاملGeometric Wavelets for Image Processing: Metric Curvature of Wavelets
We introduce a semi-discrete version of the FinslerHaantjes metric curvature to define curvature for wavelets and show that scale and curvature play similar roles with respect to image presentation and analysis. More precisely, we show that there is an inverse relationship between local scale and local curvature in images. This allows us to use curvature as a geometrically motivated automatic s...
متن کاملScalable Color Image Indexing and Retrieval Using Vector Wavelets
This paper presents a scalable content-based image indexing and retrieval system based on vector wavelet coefficients of color images. Highly decorrelated wavelet coefficient planes are used to acquire a search efficient feature space. The feature space is subsequently indexed using properties of all the images in the database. Therefore the feature key of an image does not only correspond to t...
