ViSEvAl ViSualisation and EvAluation

Overview What is evaluation?  Evaluation process  Metric definition ViSEvAl  Description  Installation  Configuration  Functionalities

Evaluation process General overview

Metric definition Metric = distance + filter + criteria Distance: associate detected and annotated objects  Spatial: compare bonding boxes area  Temporal: compare time intervals Filter: selects which object to evaluate  Specific type, distance to the camera,... Criteria: how the property of detected and annotated objects is similar?  4 tasks: detection, classification, tracking, event detection

ViSEvAl plugins 1/2 Loading video  ASF-Videos, Caviar-Images, JPEG- Images, Kinect-Images (hospital), OpenCV-Videos (Vanhaeim), PNG-Images Distance  Bertozzi, dice coefficient, overlapping Filter  CloseTo, FarFrom, Identity, TypeGroup

ViSEvAl plugins 2/2 Criteria  Detection: M1.X 2 criteria (M1.1: area, M1.2: silhouette)  Classification: M2.X 2 criteria (M2.1: type, M2.2: sub type)  Tracking: M3.X 6 criteria (M3.1: F2F, M3.2: persistence, M3.4 (tracking time), M3.5: confusion, M3.6, M3.7: confusion + tracking time, M3.8: frame detection accuracy)  Event: M4.X 4 criteria (M4.1, M4.2: begin and end time, M4.3: common frame, M4.4: common time)

ViSEvAl: inputs A set of XML files Detection: XML1 file -> sup platform Recognised event: XML3 file -> sup platform Ground truth: xgtf file -> Viper tool Time stamp file for time synchronisation : xml file -> createTimeStampFile.sh script provided by ViSEvAl

ViSEvAl installation Get the sources  sup svn repository  cd sup/evaluation/ViSEvAl/ Run intall.sh at the root of ViSEvAl folder  Dependence: Librairies: QT4 (graphical user interface, plugin management), gl and glu (opengl 3D view), xerces-c (XML read), opencv (video read) Tool: xsdcxx (automatically compute C++ classes for reading XML files) cd bin/appli; setenv LD_LIBRARY_PATH../../lib Run./ViSEvAlGUI chu.conf

ViSEvAl: two tools ViSEvAlGUI  Graphical user interface  Visualise detection and ground truth on the images  User can easily select parameters (e.g. distance, threshold,...)  Frame metrics results are computed in live ViSEvAlEvaluation  Generate a.res file containing the results of the metrics  Frame, temporal and event metrics are computed  User can evaluate several experiments Same configuration file for the both tools
