Application of Image analysis
Determination of animal movement, using image
analysis system.
The image analysis system offers a possibility to determine
the movement of objects in image by tracking them from one image
to another. The determination was based on the different in light
between two squence images. Every time the animal moves from one
position to another, pixels in image will change their light
intensity and this will indicated movement. An experiment has
been done in research Center Foulum, Denmark to determine the
pig's activities by estimated their movement in pig's pen. The
animal movement can also determine either automatic or semi
automatic. The automatic method has done by using the different
in light intensity between two images, while the semi automatic
method has done by using x and y position of coordinators in
image, using a computer mouse and well trained operator to choose
the x,y points on image and estimate the distance travel of
animals. These two methods have been published in scientific
conferences, one in Minnesota, USA and the other in Saumur,
France.
