Computing the Mean Required for Gaussian Model Construction

1. CENTER: Calculates the mean required for Gaussian model establishment, typically using sample data averaging in color spaces like YCbCr or HSV. 2. CHROMADIST: Plots skin color point distribution for visual analysis of chrominance characteristics. 3. COLORDISTPLOT: Visualizes Gaussian model parameters through probability density plots. 4. FACE: Direct RGB space segmentation (discontinued due to poor performance under varying lighting). 5. ZHIFANGTU: Grayscale histogram analysis for luminance distribution examination. 6. SKINMODEL: Constructs probabilistic skin color model using Gaussian mixture models. 7. SEGMENTSKIN: Performs skin segmentation with region labeling, area filtering, and aspect ratio validation. 8. Supporting subroutines for preprocessing and postprocessing operations.
