Interactive segmentation and contour extractionfor automatic phenotyping of Lipizzaner horses

In this paper we introduce a new custom software that was developed to support researchers in their study of exterior movement characteristics of the Lipizzaner horses. It uses an interactive image segmentation algorithm to segment a single horse in a given image from the background. The interactive algorithms offer a good tradeoff between accuracy and user interaction and allows faster segmentation than manual tools. Based on the resulting foreground mask of the horse, the whole contour or a segment of it can be exported for further analysis.
