|
||
|
||
## Build Status
|
||
|
||
| Master | Development |
|

[](https://ci.appveyor.com/project/jfmcarreira/calyp/branch/master)
|
||
|
||
|
||
## Features
|
||
- Support for libavformat and libavcodec;
|
||
- Support for wide range of raw video formats;
|
||
- Support up to 16 bits per pixel
|
||
- Support for OpenCV image/video processing library
|
||
- Advanced frame zoom with easy to use pan function
|
||
- Synchronized zoom across several videos (perfect for comparison operations)
|
||
- Useful information in status bar, *e.g.*, pixel information
|
||
Useful sidebars with frame information, *e.g.*, frame histogram
|
||
- Constant growing libs for stream and frame processing (CalypStream and CalypFrame)
|
||
- Advanced API for frame/video processing algorithms
|
||
- Frame level quality measurement API based on the CalypFrame class
|
||
- Powerful command-line tool for quality and frame processing algorithms (uses the referred APIs)
|
||
|
||
## Modules
|
||
- CalypLib: Low level library
|
||
- CalypModules: Abstract interface for frame processing modules
|
||

||
- CalypTools: High level command line interface
|
||
|
||
## Supported Quality Metrics
|
||
- Peak Signal-to-Noise Ratio (PSNR)
|
||
- Structural SIMilarity (SSIM)
|
||
- Mean Square Error (MSE)
|
||
- Weighted Spherical PSNR (WS-PSNR)
|
||
|
||
## Frame Processing Modules
|
