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.
