Abstract: An exercise feedback system generates biofeedback based on physiological adaptations. The exercise feedback system processes physiological data from sensor-equipped garments worn by athletes while performing exercises. The exercise feedback system may use a trained model to determine classifications of segments of the physiological data. Classifications may represent a type of physiological adaptation, for example, power, strength, hypertrophy, endurance, or speed. Athletes can focus on one or more physiological adaptations, which may be based on a specific sport or training goal of an athlete. The exercise feedback system may also use other types of sensor data from the garments such as motion data or bioimpedance information. The exercise feedback system can generate biofeedback including metrics determined using the classifications. For example, the metrics indicate training load aggregated over multiple muscles or workouts, or the biofeedback may notify athletes regarding a risk of injury.

Abstract: Systems, methods, and computer program products for creating composite images. In one approach, a method for generating an image, comprises the computer implemented steps of: adding a three dimensional (3D) object to a two dimensional (2D) image; rendering a representation of one of the objects in the 2D image viewable through a transparent or semi-transparent portion of the 3D object; and rendering an effect of refraction on one of the objects in the 2D image viewable through the transparent or semi-transparent portion of the 3D object. Additional embodiments are also presented.

Abstract: Systems, methods, and computer program products that provide broadcast-quality photo-realistic rendering of one or more 3D objects added to a still frame (photo mode), or series of frames (movie mode). The basic steps performed during creation of an image include analysis of a 2D image frame during a set up sequence, adding a 3D object to the frame, and adding visual effects to the frame with little or no user intervention, the visual effects including but not limited to shadowing, reflection, refraction, and transparency.

Abstract: Systems, methods, and computer program products that identify and allow manipulation of shadows in a still frame (photo mode), or series of frames (movie mode). Manipulation of shadows includes such things as adjustment of shadow boundaries, softening of shadow boundaries, adjustment of shadow properties, and even removal of shadows altogether.
