Three demos were presented in the seminar of "How to apply image processing and computer vision with MATLAB" held in MATLAB EXPO 2013 in Japan
- Count the number of each nuts
There are five kinds of objects (nuts, almond, corn etc) in the picture. This demo shows how to distinguish each one and count the number of them using morphology processing, blob analysis, color space conversion, machine learning etc.

The same folder also contains a demo counting objects attached each other.

- Augumented Reality demo
Shooting a picture (white bear) on the wall and in the viewer on the MATLAB the bear plays on the ice. Even if camera moves (right/left, near/far) the bear is still playing at the place of still picture.
This script demonstrates local feature matching, point tracker, video stream processing
(Due to limitation of the file size, movie files are not included)

- Quick Demo using Kinect
Measure the length of a bar.
hold the bar with your open palms.
even if the bar leans against the camera, i.e., the length on the image is shrunk, the length is measured correctly. See the screen shot, which is 100cm bar and detected as 101cm
