Range image quality assessment by Structural Similarity
We propose a new quality metric for range images that is based on the multi-scale Structural Similarity (MS-SSIM) Index. The new metric operates in a manner to SSIM but allows for...

Evaluating Perceptually Prefiltered Video
Perceptual prefiltering is the process of enhancing relevant portions of an image or of a video, and of simplifying contextual information in order to improve the perceived quali...

Directional motion-compensated spatio-temporal fuzzy filtering for quality enhancement of compressed video sequences
We propose a directional fuzzy lter to enhance the quality of compressed video sequences. A motion compensated spatiotemporal lter (MCSTF) is applied to intra-frame and inter-fram...

Gradient descent optimization of smoothed information retrieval metrics
Abstract Most ranking algorithms are based on the optimization of some loss functions, such as the pairwise loss. However, these loss functions are often different from the criter...

Evaluation of super-voxel methods for early video processing
Supervoxel segmentation has strong potential to be incorporated into early video analysis as superpixel segmentation has in image analysis. However, there are many plausible super...
