The analyzer developed observed if there are two skin areas in the sequence image and the one of the right side contracts and expands significantly. The system provides accurate results at distance of one meter. The following is another set of sample points taken at different locations at distance of 1.5 meter within the environment. The system also provides accurate results. The system still provide good result but with larger standard deviation and mean error.
Orientation works reliably in various scenes.
However, z-axis estimation does not yield the same result. As moving to the new scene, z-axis measurement varies considerably from the old setting. This is expected since at different scene location, different amount illumination may cause the blob size the significantly change and distort estimated distance. About 13 distance reading and 17 orientation readings are taken at location 1. The following is the same type of measurement but taken at location 3 where there is less illumination.
