Title Contour extraction and Modelling of Horses using Background Subtraction and Active Shape Models
Abstract Anatomical information about horses can be extracted from still images, using markers placed on the horse and manual inspection of marker positions. However, it is a time-consuming process both to place markers and to extract coordinate data from them manually. It is therefore of interest to study if computerized image analysis can be used to extract the contour of horses from images taken without too strict limitations on the setup, and if contour features can be extracted and used to obtain reliable anatomical measurements, thereby reducing the amount of manual work needed to collect the data.

In this master's thesis, we propose a segmentation method based on background subtraction for finding the contour of horses (and other objects) with consideration to noise and shadows, and use active shape models to locate and identify contour features. The methods are implemented as a MATLAB program. We also discuss problems and limitations of the methods, as well as possible future extensions of the project.
