Video Offset Distortion Calculator

This documentation gives a brief introduction to the spatial scalable video offset distortion calculator.

For details on how the offset distortion is calculated and how it can be used in networking research, see "".

In the program window illustrated below, the user has to select two YUV video sequences in the YUV 4:2:0 format. The output file will be written into a standard comma separated value file (CSV) that allows easy access to the values in popular spreadsheet programs. The original enhancement layer is supposed to be in CIF format (Org. EL). The encoded base layer is supposed to be in QCIF format (Enc. BL).



Currently, the program supports calculation of the video offset distortion values as RMSE values for the QCIF and CIF formats, which must be selected by the user.  
The offset distortion values are calculated for each individual frame and are stored in the CSV output file in the following manner:

Frame#,RMSE(offset=1frame),RMSE(offset=2frames),...,RMSE(offset=Max.fr.)

The user can select the maximum number of offsets for which the distortion values are calculated for each frame.
