| Popis: | Due to the isotropic edge enhancement, the vortex phase filters are of commonly used in spatial filtering. In general, these filters employ a spiral phase mask on the Fourier plane, the square modulo from this convolution is the edge enhanced image. Nonetheless, several digital filtering applications based on vortex phase filters leave aside the complex-valued information. This complex-valued field is obtained from the Laguerre-Gauss transform application over static or dynamic events, namely single images or frames in a video. We propose the usage of complex field to locate and track phase singularities in dynamic events. In this sense, not only each object edges in a given scene are enhanced, but also phase singularities related to each object. This imprints a characteristic marker given by the assignation of optical vortex to objects with unique core structure properties, allowing for tracking a particular object in dynamic events.
