Video Databases & Shape Modelling for Sign Language (midterm)

  1. 1. Video Databases & Shape Modelling for Sign Language Live Image Gesture Recognition
  2. 2. Purpose of Gesture Recognition <ul><li>Create a software interface that will interpret Irish Sign Language from live video </li></ul><ul><li>Interface will work on a medium range PC using a USB Webcam </li></ul>
  3. 3. Creating Gesture Database <ul><li>Principal Components Analysis (PCA) used to compress sets of gesture images </li></ul><ul><li>Differences between images stored in the database as a 3D point </li></ul><ul><li>Movement of the arm forms a continuous curve on a 3D graph </li></ul><ul><li>Database will be hierarchical, with similar gestures grouped together </li></ul>
  4. 4. Comparing to the Database <ul><li>Acquisition one image at a time from the video source </li></ul><ul><li>Extract arms and head from the image by using skin colour segmentation </li></ul><ul><li>Compare image to the Database to match up arm and hand position </li></ul><ul><li>Interpret the gesture and display to the interface </li></ul>
  5. 5. Next Steps <ul><li>Increase accuracy of Database matching </li></ul><ul><li>Speed up image manipulation algorithms e.g. finding arm position </li></ul><ul><li>Create the Interface software </li></ul><ul><li>Develop Interface backend, including the Database framework, in a low level language </li></ul><ul><li>Convert all scripts and code to the one language </li></ul>
