Left object Dataset

Description:

A number of video clips were recorded acting out the scenario of interest: left objects. 31 sequences of two minutes have be recorded, showing different left objects scenarios (1 or more objects, person staying close to the left object, etc).
The 31 scenarios have been recorded using 2 different cameras (not synchronised), with two different views:
  • a Panasonic camera - miniDV, model NV-DS28EG (camera1)
  • a Sony camera - miniDV, model DSR-PD170P (camera2)
The videos have the following caracteristics:
  • A resolution of 720x576 pixels
  • 25 frames per second
  • A compression using MPEG4
  • The file sizes are of 75 Mo for camera1 and 65 Mo for camera2.
Here are images extracted from camera1 and camera2:

Note that in each sequence, nothing appends before 30 seconds, and after 1m45s.

All the sequences are annotated using XML format. Each sequence is associated with a ".xml" annotation file with the same name ending by .gt.xml. Here is an exemple of xml file:
 
<?xml version="1.0" encoding="UTF-8" ?>
     <event_history>
            <event>
                    <time>2008-07-31T16:56:48.440000</time>
                    <name>LeftObject</name>
                    <parameters>
                            <screenposition>-0.445833,-0.108333</screenposition>
               </parameters>
       </event>
            <event>
                    <time>2008-07-31T16:56:53.920000</time>
                    <name>LeftObject</name>
                    <parameters>
                              <screenposition>-0.004167,0.395833</screenposition>
              </parameters>
       </event>
</event_history>

The XML file is composed of one major section "event_history" containing the list of all events detected in the sequence.
Each of the "event" contains the following indications:
  • <time>: the precise time when the event has been detected
  • <name>: the name of the detected event, here a left object
  • <parameters>: some parameters, here we have the screen position of the object (normalized position of the center of the bounding box)
The total size of the compressed database is about 2.4GB, separated into 8 zip files.
