The modules use much RAM during launching. Shutter speed: must not be too low (more than 1/50), because in such a case the blurring of moving objects will occur). Horizontal turn of camera from face plane:Įxposure and brightness: ensuring that the face is clearly seen (if the camera faces the light source, the overexposed background is acceptable).
The camera angle between the face direction and the lens axis must not exceed 30°.Įxamples of non-compliance with the requirements The camera must directly face the people to be recognized. The distance between the pupils of a face to be recognized must be at least 30 pixels. In such a case, the camera elevation angle must not exceed 35°. The camera may be placed above the face level, directly facing the people to be recognized. sunlight from the window) resulting in the overexposure of one part of the face is not acceptable. There must be no mirror surfaces giving reflections in the frame (glass, mirrors, etc.). The faces must be fully seen in the frame. No blurring of moving people’s faces is allowed. Significant compression artefacts are not acceptable. The image quality must be medium or better. The overexposed background is acceptable. If the camera is installed opposite a bright source of light (sun behind the entrance door, etc.), it is required to adjust the exposure or brightness in such a way that the face in the frame is light. Illumination of faces in the frame must be uniform and constant.
No mirrored (horizontally flipped) stream. Optimum resolution for the module’s operation: HD or FullHD. The module is tolerant to appearance modification: Lateral illumination is not permissible (e.g. No scanning artifacts, no retakes from screens The images to be added to the database must conform to the following requirements:įace position: strictly face forward, no turns The neural network works with the 64-bit version of Eocortex only.
