SSim: NASA Mars Rover Robotics Flight Software Simulation
IEEE Aerospace Conference, 2019Each new Mars rover has pursued increasingly richer science while tolerating a wider variety of environmental conditions and hardware degradation over longer mission operation duration. Sojourner operated for 83 sols (Martian days), Spirit for 2208 sols,

SSIM Prediction for H.265/HEVC based on Convolutional Neural Networks
Visual Communications and Image Processing, 2019In signal compression, distortion information is significant for rate distortion optimization. In this paper, we propose a convolutional neural network (CNN) to predict distortion information for H.265/HEVC.

Rate-SSIM optimization for video coding
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011The structural similarity (SSIM) index has been found to be a good indicator of perceived image quality. In this paper, we propose a rate-SSIM optimization scheme for mode selection in H.264/AVC video coding. To derive the Lagrange multiplier based on the properties of input sequences, a novel reduced-reference statistical SSIM model and a source-side ...

Improved SSIM IQA of contrast distortion based on the contrast sensitivity characteristics of HVS
IET Image Processing, 2018Currently, the structural similarity index metric (SSIM) is recognised generally and applied widely in image quality assessment (IQA). However, using SSIM to evaluate contrast-distorted images from TID2013 and CSIQ databases is low effective.

Selecting the proper window for SSIM
SPIE Proceedings, 2012The structural similarity index (SSIM) is a well-known metric in the field of image quality assessment (IQA). It is a full-reference metric that uses a sliding window to determine local quality/distortion measures between two images (based on a combination of luminance, contrast, and structural measurements from each image's window), and combines ...

SSIM: a software levelized compiled-code simulator
24th ACM/IEEE conference proceedings on Design automation conference - DAC '87, 1987This paper presents a new logic simulation technique that uses software levelized compiled-code (LCC) for synchronous designs. Three approaches are proposed: C source code, target machine code and interpreted code. The evaluation speed for the software LCC simulator (SSIM) is about 140,000 (gate) evaluations per second using C source code or target ...

SSIM based perceptual distortion rate optimization coding
SPIE Proceedings, 2010The current rate distortion optimization (RDO) coding schemes usually use the Sum of Absolute Difference (SAD) or Sum of Square Difference (SSD) as the distortion metric. However, neither SAD nor SSD correlates with the human visual system (HVS) very well. To develop a perceptual distortion based video encoder, we employ the Structural Similarity (SSIM)

SSIM-inspired image denoising using sparse representations
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011Perceptual image quality assessment (IQA) and sparse signal representation have recently emerged as high-impact research topics in the field of image processing. Here we make one of the first attempts to incorporate the structural similarity (SSIM) index, a promising IQA measure, into the framework of optimal sparse signal representation and ...

SSIM for video representing and matching
2013 6th IEEE/International Conference on Advanced Infocomm Technology (ICAIT), 2013This paper propose a compact video representation using SSIM assessment for matching video sequences. As opposed to using the complex features extracting methods to analysis color and motion information through the sequence. We use the similarity index of successive frames to produce a representation of videos.
