GMM Background Modeling with Video Processing

The original article mentioned using the BMP framework for image processing, which we have expanded to handle video input. This implementation first initializes 3-5 Gaussian models to represent different background components. For each incoming video frame, the code performs pixel-level matching against the existing Gaussian mixtures using statistical distance metrics. The model update mechanism employs an adaptive learning rate to accommodate gradual scene changes while maintaining stability against temporary fluctuations. The algorithm's core functionality includes calculating Mahalanobis distances between current pixels and model distributions, followed by selective updates of Gaussian parameters (mean, covariance, and weight) based on match results. Mismatched pixels are identified as potential foreground elements. This approach effectively handles multimodal backgrounds and lighting variations through its probabilistic framework. Using video input enables better capture of dynamic scene variations and continuous frame processing, yielding more accurate and stable background modeling results. This implementation finds significant applications in computer vision systems, video surveillance analytics, and motion detection scenarios where robust background subtraction is crucial. The code structure separates model initialization, frame processing, and parameter update phases, allowing modular customization. Key functions include Gaussian weight normalization, background model maintenance, and foreground segmentation with noise suppression mechanisms.
