IP3 2021-Video & Image Processing 4 (LOT 12923)

This lot is generally related to video processing. Techniques are disclosed to model a background of a video which accounts for dynamic background change according to a pattern. The technique generates a combined color covariance matrix of a video image and input image, estimates a probability density, and updates a background model. Few techniques generate a feature point space, develop an uncertainty model and perform a variable bandwidth mean shift on the feature space points. The technology may be implemented in video processing services, surveillance applications, object detection and monitoring, computer vision applications, video segmentation, etc.
