Main focus

Main Focus

  • Spatio-temporal Query Processing

  • SQL like Video Query Languages


Introduction

Introduction

  • Spatio-Temporal Query processing

  • Content-based retrieval

  • Video Databases

  • Multimedia Databases


Three stages

Three Stages

  • Spatio-Temporal Query Processing is carried out in three main stages:

    • Query Recognition

    • Query Decomposition

    • Query Execution


Vdbms languages

VDBMS Languages

  • Video SQL

  • MOQL

  • MTQL

  • AVIS

  • Video Star

  • CVQL


Bilvideo vdbms

BilVideo VDBMS

  • System Architecture

  • Knowledge-Based Structure

Bilvideo query language

BilVideo Query Language

  • Features of the language

  • Basic Query Types

  • Example Applications


Features of the language

Features of the Language

  • BilVideo Query Languages has four basic statements for retrieving information

    • Select video from all [where condition];

    • Select video from videolist where condition;

    • Select segment from range where condition;

    • Select variable from range where condition;


Basic query types

Basic Query Types

  • Object Queries

  • Spatial Queries

  • Temporal Queries

  • Aggregate Queries


Object queries

Object Queries

  • To retrieve salient objects

  • Examples:

    • Query1:

      • Select segment from all where appear(o1);

  • Query2:

    • Select segment , X from 1 where appear(o1,X)

      And X!=o1;


Spatial queries

Spatial Queries

  • To Query Videos by Spatial Properties

  • Three Categories:

    • Directional relation in 2D space

    • Topological relation in 2D space

    • 3D relations in 3D space


Example applications

Spatio temporal query processing

Spatio-Temporal Query Processing

  • Query recognition

  • Query Decomposition

  • Query Execution

  • Interval Processing


Query processing phases

Query Processing Phases


Conclusion

Conclusion

  • An SQL-like textual query language for spatial-temporal queries on video data was proposed

  • BilVideo query language provides query support through external predicates for application dependent data.

  • Working on integrating the support for semantic and low level video queries into BilVideo by extending its query processor and query language.
