Visual Quality Index Implementations

Contact:

Description:
Implementation of some metrics:
  • ess
  • lss
  • psnr
  • psnry
  • ssim
  • lfbvs
  • nice
  • leg
  • sun10a
  • yao09a
The implementation aims to preventing image file type hassle and usability from shell scripts rather than fast runtime.
Note: This software uses freeimagelibplus.

Changelog:
Version 0.3.1 (2011-7-27):
Usage:
  • Metrics added:
  • sun10a from Jing Sun and Zhengquan Xu and Jin Liu and Ye Yao: ''An objective visual security assessment for cipher-images based on local entropy'', 2010.
  • yao09a from Y. Yao and Z. Xu and J. Sun: ''Visual security assessment for cipher-images based on neighborhood similarity'', 2009.
Version 0.3 (2011-5-24):
Usage:
  • Metrics added:
  • Local edge direction and gradient (LEG) from An Effective and Efficient Visual Quality Index Based on Local Edge Gradients by Hofbauer et al.
  • Local feature based Visual Security (LFBVS) from Visual Security Evaluation for Video Encryption by Tong et al.
  • Natual image contour evaluation (NICE) from Natural Image Utility Assessment using Image Contours by Rouse et al.
Interface:
  • Options can now be passed to metrics with -o, the metric has to deal with the options as it sees fit.
    NOTE: This breaks compatibility with older metrics. This can be fixed by including a dummy options function:
    void metric_passopt(char *passopt){ }
Version 0.2:
Added support for yuv 4:2:0 videos.
Version 0.1:
Initial release
