Journal ArticleDOI
Contextual and Variational Contrast Enhancement
Turgay Celik,Tardi Tjahjadi +1 more
TL;DR: An algorithm that enhances the contrast of an input image using interpixel contextual information and produces better or comparable enhanced images than four state-of-the-art algorithms is proposed.
Journal ArticleDOI
Automatic Image Equalization and Contrast Enhancement Using Gaussian Mixture Modeling
Turgay Celik,Tardi Tjahjadi +1 more
TL;DR: An adaptive image equalization algorithm that automatically enhances the contrast in an input image that is free of parameter setting for a given dynamic range of the enhanced image and can be applied to a wide range of image types.
Journal ArticleDOI
Silhouette-based gait recognition using Procrustes shape analysis and elliptic Fourier descriptors
TL;DR: Experimental results show STM-SPP outperforms several silhouette-based gait recognition methods.
Journal ArticleDOI
Robust view-invariant multiscale gait recognition
TL;DR: A two-phase view-invariant multiscale gait recognition method which is robust to variation in clothing and presence of a carried item and a weighted random subspace learning based classification is used to exploit the high dimensionality of the feature space for improved identification.
Journal ArticleDOI
Multiscale texture classification using dual-tree complex wavelet transform
Turgay Celik,Tardi Tjahjadi +1 more
TL;DR: A multiscale texture classifier that exploits the Gabor-like properties of the dual-tree complex wavelet transform, shift invariance and six directional sub bands at each scale, and uses a feature vector comprising of a variance and an entropy at different scales of each of the directional subbands.
