Abstract

METHOD AND SYSTEM FOR CROWD LEVEL ESTIMATION [0059] Methods and systems for crowd level estimation are provided. The system for crowd level estimation includes an input module and a crowd level estimation module. The input module receives an input image of a crowd and the crowd level estimation module estimates a crowd level of the crowd in the input image in response to a crowd density level. FIG. 7
