Fake Image Detection by Illumination Color Classification
As images can fetch more information than words, most of the people are dependent on them for communication and use them as powerful evidence in courts and media companies. Nowadays, however, advanced image processing tools and graphical editing techniques makes it easier to edit and modify the digital image. This diminishes our trust in photographs and objects pictures as evidence for real wor...
متن کاملIllumination-Invariant Color Image Correction
This paper presents a new statistical approach for learning automatic color image correction. The goal is to parameterize color independently of illumination and to correct color for changes of illumination. This is useful in many image processing applications, such as color image segmentation or background subtraction. The motivation for using a learning approach is to deal with changes of lig...
متن کاملDense Depth Maps by Active Color Illumination and Image Pyramids
An efficient hierarchical technique is presented for obtaining dense stereo correspondence using a color image pyramid. We show that matching results of high quality are obtained when using the hierarchical chromatic Block Matching algorithm. Furthermore, we present some results for parallel implementations of the algorithm. Most stereo matching algorithms can not compute correct dense depth ma...
متن کاملColor Image Registration under Illumination Changes
The estimation of parametric global motion has had a significant attention during the last two decades, but despite the great efforts invested, there are still open issues. One of the most important ones is related to the ability to recover large deformation between images in the presence of illumination changes while kipping accurate estimates. Illumination changes in color images are another ...
متن کاملAn Illumination Invariant Image Descriptor for Color Image Matching
Color image descriptors have been used extensively and successfully in many computer vision applications. However, object colors are sensitive to illumination changes which in turns will affect the performance of object recognition if the image descriptors used are not robust to these changes. To increase photometric invariance and discriminative power, this study proposes an image descriptor f...
