Open Lab Egypt (OLE) – Video Interactive Projects

OLE's picture

OLE

A long term project based on several workshop phases between Cairo and Alexandria, initiated with aims of developing the use of electronic interface within Art creation in Egypt. The project phases will provide introduction to the technique, experimentation with tools, investigating ideas and concept evaluation.

Workshop is organized by:

OLE Alexandria workshop

November 25 to 4th of December, 2009

Deadline: 20 November

Computer Vision Techniques for Interactive Installations

Participants will learn the basics of Computer Vision Techniques and then be able to start applying them to artistic projects.

During the 10 days of workshop a space of reflection, investigation and collaborative work will be developed in a context of production, encounter, dialogues and collective learning where several tutors exert of technical advisers of the artists and work groups who develop each one of the proposals.

The platforms taught are all open - software and hardware - but may be adapted to any system.

Contents:

  1. Introduction to Computer Vision
  2. Processing Live Video
  3. Processing of data
  4. Motion Detection in a public space
  5. Control of Video and Audio
  6. Work on projects suggested by the participants

Duration:

10 days, including open seminars and demonstration of resulting works.

Tutors:

Yves Degoyon & Lluis Gomez i Bigorda

Day 1: Introduction to Computer Vision

Theory:

  1. Image and Video Format Concepts ( RGB, YUV, ... )
  2. Static and Dynamic processing of images and video frames.
  3. Movement Detection example - Simple Tracking example - Tracking using Pattern recognition.
  4. Pattern recognition using a Statistical approach.

Practice:

  1. Conversion of videos to a format suitable for analysis.
  2. Simple Movement detection example.
  3. Simple Tracking example.

Objective:

  • Showing a panorama of existing computer vision techniques

Day 2: Processing Live Video

Theory:

  1. Which camera to use? What to expect?
  2. The importance of lightning and contrast.
  3. Noise removal and filtering.
  4. Advanced filtering and pre-processing of video.

Practice:

  1. Using simple examples using different kind of inputs.
  2. Measure and see the importance of filtering.
  3. Use of video pre-processing techniques.

Objective:

  • Stabilize the first examples with a more precise detection and tracking)

Day 3: Processing of data

Theory:

  1. Connecting analysis data to media processing.
  2. Smoothing data to get more stable results.

Practice:

  1. Process incoming data to produce interaction.
  2. Connect first examples to a media production unit (sound and/or video)
  3. Calibrating inputs to get the expected result.

Objective:

  • Using incoming data and process it to produce interaction)

Day 4: Choose the right technique in the right context

Theory:

  1. Outdoor/Indoor context.
  2. Camera/Lighting setup for a ‘Darkroom’.
  3. Importance of background and contrast.

Practice:

  1. Using basic examples in different context (outdoor, dark room)
  2. Playing with contrast and background

Objective:

  • Determine the best technique and setup for different contexts)

Day 5-10: Thematic Working Groups ( Practice )

  1. Motion Detection in a public space
  2. Tracking in the context of dance and theater.
  3. Augmented reality.
  4. Interactive sound instruments.

Objective:

  • Realize a few prototypes using computer vision techniques for different kind of applications, towards a real application).
