Journal ArticleDOI
Unsupervised Change Detection in Satellite Images Using Principal Component Analysis and $k$ -Means Clustering
TL;DR: A novel technique for unsupervised change detection in multitemporal satellite images using principal component analysis (PCA) and k-means clustering and Experimental results confirm the effectiveness of the proposed approach.
Journal ArticleDOI
Fire detection in video sequences using a generic color model
Turgay Celik,Hasan Demirel +1 more
TL;DR: A rule-based generic color model for flame pixel classification using YCbCr color space to separate the luminance from the chrominance more effectively than color spaces such as RGB or rgb is proposed.
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
Fire detection using statistical color model in video sequences
TL;DR: A real-time fire-detector that combines foreground object information with color pixel statistics of fire and the use of a generic statistical model for refined fire-pixel classification 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.
