In this paper, a novel method for the lossless compression of the interferometer hyperspectral instrument Large Aperture Static Imaging Spectrometer (LASIS) data is presented. This scheme rests upon the combination of data rearrangement and band ordering of LASIS three dimensional image and the recently presented CCSDS-123 lossless multispectral & Hyperspectral image compression standard. Firstly,...
When different images are presented to two eyes, they compete for perceptual dominance, such that a region of one image is visible while corresponding region of the other is suppressed. This visual phenomenon is called binocular rivalry. Binocular rivalry may be introduced in stereoscopic images of natural scene, leading to strong visual discomfort and visual fatigue. When binocular differences exceed...
Binocular rivalry is a visual phenomenon that occurs when two eyes are presented with different patterns. Instead of being fused to form a unitary visual impression, the two patterns may be perceived alternately or evoke a peculiar shimmering effect. In stereoscopic images, corresponding regions in two views may be dissimilar due to artifacts from lossy video processing, e.g., transmission and compression...
To exploit both spatial and temporal correlation of video signal, a Second Order Prediction (SOP) scheme has been presented to eliminate the spatial correlation existing in motion compensated residue. Although SOP achieves better RD performance by adopting residue prediction in Mode Decision (MD) stage, it can be further improved by combining residue prediction into Motion Estimation (ME). Our analysis...
AVS-Part 2 is a mainstream video coding standard with high compression efficiency similar to H.264/AVC. A technique named Second Order Prediction (SOP) has been presented based on H.264/AVC to decrease the signal correlation after motion-compensated prediction. To achieve better coding performance, this paper presents a method named Block-based Second Order Prediction (BSOP) to ameliorate SOP to adapt...
In this paper, a novel spatial prediction method is proposed to improve prediction accuracy and capture the dynamics of different video contents. The method adaptively generates optimized spatial prediction modes according to the local feature of coded image. The optimization is conducted by analytical calculations to minimize the energy of prediction residue. Experimental results show that the method...
Based on a relatively simple motion assumption, the technique of motion-compensated prediction will result in large residue when dealing with video contents containing complex motions. To achieve higher coding efficiency, this paper presents a method named second order prediction (SOP) to exploit remaining signal correlation after motion-compensated prediction. Demonstration and analysis on the SOP...
