Non-Local Means Variants for Denoising of Diffusion-Weighted and Diffusion Tensor MRI
Abstract. Diffusion tensor imaging (DT-MRI) is very sensitive to corrupting noise due to the non linear relationship between the diffusionweighted image intensities (DW-MRI) and th...

DCT Coefficient-Based Error Detection Technique for Compressed Video Stream
: In the process of transmission of digital encoded video bit streams over physical network, the data is corrupted by random bit errors, which has a several effect on the decoded v...

Redundant-wavelet watermarking with pixel-wise masking
An algorithm is presented which implements image watermarking in the domain of an overcomplete, or redundant, wavelet transform. This algorithm expands on a previous method which ...

Perceptual Sharpness Metric (PSM) for Compressed Video
Sharpness, one of the most effective factors in video quality assessment, usually dominates the first impression of the representation of the compressed video or image signals. I...

Analytical motion blur rasterization with compression
We present a rasterizer, based on time-dependent edge equations, that computes analytical visibility in order to render accurate motion blur. The theory for doing the computations...
