CGVQM+D: Computer Graphics Video Quality Metric and Dataset

Computer graphics forum (Print)
While existing video and image quality datasets have extensively studied natural videos and traditional distortions, the perception of synthetic content and modern rendering artifacts remains underexplored.

Using compute unified device architecture-enabled graphic processing unit to accelerate fast Fourier transform-based regression Kriging interpolation on a MODIS land surface temperature image

Journal of Applied Remote Sensing, 2016
Kriging interpolation provides the best linear unbiased estimation for unobserved locations, but its heavy computation limits the manageable problem size in practice. To address this issue, an efficient interpolation procedure incorporating the fast Fourier transform (FFT) was developed.

Random Sampling SVM Based Soft Query Expansion for Image Retrieval

Fourth International Conference on Image and Graphics (ICIG 2007), 2007
During digital image deblurring, a priori knowledge of blurred image is incorporated into regularization to adoptively adjust the global regularization parameter for better preserving the edge in the image and suppressing ringing effects. So the weighting matrix in the spatial domain is constructed by calculating the gradient amplitude of each pixel ...
