A Synchronous Fragile Watermarking Scheme for Erroneous Q-DCT Coefficients Detection
In video communications over error introducing channels, error concealment techniques are widely applied in video decoder for good subjective images output. However, a damaged MB ...

Impact of Correlation on Linear Precoding in QSTBC Coded Systems with Linear MSE Detection
— In this paper, we study a wireless multiple-input multiple-output system in a Rayleigh flat-fading environment with correlation among the transmit antennas. We assume that the...

Do Colour Interest Points Improve Image Retrieval?
In image retrieval scenarios, many methods use interest point detection at an early stage to find regions in which descriptors are calculated. Finding salient locations in image d...

A probabilistic ranking framework using unobservable binary events for video search
Recent content-based video retrieval systems combine output of concept detectors (also known as high-level features) with text obtained through automatic speech recognition. This ...

High Dynamic Range Imaging: Spatially Varying Pixel Exposures
While real scenes produce a wide range of brightness variations, vision systems use low dynamic range image detectors that typically provide 8 bits of brightness data at each pixe...
