Pocket Schlieren

Pocket schlieren is an android app to democratize flow visualization. It is based on Background Oriented Schlieren. Pocket schlieren enables users to directly capture, process, and visualize flow phenomena on their smartphones. The underlying algorithm incorporates consecutive frame subtraction (CFS) and optical flow (OF) techniques to compute the density gradients inside a flow. It performs on both engineered and natural background patterns.
