MySQL processing database
Within VQEG JEG Hybrid's efforts on reproducible research, one of the most important steps is to provide the information how to reproduce PVS files, indicators, and objective measures. An information database in the form of a MySQL database seems appropriate.
Several types of items may be distinguished in a complete processing chain for video quality prediction:
- In the simplest case, a file storage item is a URL and a StorageDescriptionItem.
- The StorageDescriptionItem relates to the different types of file and data storage. Notably Raw Video Sequences, Processed Video Sequences, and Bitstreams can be distinguished for FileStorageItem and SingleScore or ScorePerFrame for DataStorageItem.
- Contains all information required to transform on or several StorageItem(s) to one or several StorageItem(s), notably FileStorageItem(s) and/or DataStorageItem(s). A typical example is a video codec or an objective measure.
- Similar to FileStorageItem but contains the data directly and a StorageDescriptionItem.
Any StorageItem and ProcessingItem can be accessed by a unique code of 12 characters.
