Overview
The Video Processing Evaluation Resource (ViPER) project is intended
to provide a ground truthing and evaluation environment for visual
media. The system is currently under development, so there are
still many bugs in the program. Experimentation with the beta
version should be done at your own risk.
The
materials on this page provide a walk-through of the design and
implementation of the system currently being developed, as well
as other software and datasets. The main component of ViPER is
a ground truth viewer, which can be be used to generate and manipulate
ground truth files. The system is divided into three main components
- ViPER-GT, ViPER-PE, and ViPER-Viz.
ViPER-GT
contains modules for the recording of ground truth information.
It provides basic constraints for configuring and producing ground
truth files which describe video sequences. It contains a GUI
interface that can be used to produce frame level ground truths
from video sequences, as well as a parser for data files and a
video annotation application.
The
ViPER-PE module provides performance evaluation capabilities for
comparing computed results with appropriate ground truth information.
It provides precision and recall metrics at multiple levels, allows
user configurations of ground truth features to evaluate selected
subsets of the whole ground truth and the ability to establish
equivalence classes between terms used in the ground truth and
term used in the analysis results.
ViPER-Viz
is a module that contains a set of applications which enables
a user to compactly visualize ground truth, analysis results,
performance evaluation results, or an entire video clip, using
several flexible representations.
The
primary enhancements in this version are strict specifications
of the functionality of various components of the system, and
the ability to provide dynamic attributes and relation attributes.
