Title: Improving video analysis for the Olympic dinghy class sailing coaches and athletes

Abstract: Nowadays technology and data analytics are becoming increasingly intertwined with sports. The data can help assess performance during training and in competitive settings. However, for most sailors in the Olympic dinghy class it holds that the use of sensors during training is not standard practice and not allowed during races. To record and review their performance the coaches and athletes make use of video, shot (often by holding a camera in hand) from the a coach boat. The goal is to improve the capture, processing and analysis of videos used to train sailing athletes in the dinghy class. More specifically, the stabilization and quality of the footage taken from the coach boat that follows athletes will be improved. Next to this, of the entire recorded session only the interesting parts for the coach and athletes will be highlighted and extracted. To achieve this segmentation into clips object tracking will be used as well as methods to detect sailing manoeuvres. From these video clips the heel angle, position in boat and rudder movements can be extracted or enhanced to support the coaches in their assessment. The proposed approach should lead to a time-saving method to extract more information from the videos previously possible to support the training of the dutch Olympic sailing team.

Title: Semantic Tile Solving for Procedural Generation of Architectural Spaces

Abstract: We present an offline tile solving technique to generate complex architectural spaces. The generation is controlled by the notion of an architectural profile. An architectural profile allows to declaritively control spatial creation. It consists of semantic tiles representing building elements and declarative rules to control the generation according to architectural relations. This problem is converted to an ASP logic program and subsequently solved by an ASP solver. Our technique results in a declarative architecture generator that unifies procedurally generating building exterior, building interior and traversal in one system.
