MATLAB implementation of a classic image processing approach combining Gaussian Mixture Model background modeling and skin color detection algorithms for facial detection applications

Detailed Documentation

This addresses a fundamental challenge in image processing: how to detect human faces within images? One effective solution involves employing Gaussian Mixture Model (GMM) background modeling combined with skin color detection algorithms. Implementing this approach in MATLAB provides valuable insights into its underlying mechanisms and parameter optimization strategies for diverse image datasets. The GMM implementation typically uses the gmdistribution function to model background variations, while skin detection employs color space transformations (YCbCr or HSV) with threshold-based segmentation using functions like rgb2ycbcr and morphological operations (imopen, imclose). Through this process, we gain deeper understanding of image processing methodologies and techniques, enabling applications in broader domains such as computer vision and machine learning systems.
