Video stream and scene requirements for the Crowd Estimation VA

Requirements for the operation of the Crowd Estimation VA are given in the table:

Camera	Resolution of 256x256 pixels or higher Color: analytics works with both gray and color images No camera shake
Lighting	The best performance of the detection tool is achieved under moderate lighting. In conditions of insufficient (night) or excessive (light-striking) lighting, the algorithm performance can decrease No abrupt changes in lighting
Scene and camera angle	The background is mostly static and doesn’t change abruptly Analytics cannot work correctly: on reflective surfaces and if there are sharp shadows from moving objects if there is a repeating pattern in the scene (crosswalk) if there are objects in the scene that look like people (monuments, animals) if there are periodic movements of background objects in the camera FOV (trees, rain, and so on)
