MATLAB-Based Image Processing Implementation with Custom Algorithms

This MATLAB-based image processing implementation avoids using built-in functions and instead creates custom algorithms for: 1) Grayscale histogram visualization and calculation through pixel intensity counting, 2) Geometric transformations including horizontal/vertical mirroring and shearing using coordinate mapping, 3) Smoothing and sharpening filters via convolution operations with custom kernels, 4) Threshold segmentation using intensity-based pixel classification. Execute the main function and follow interactive prompts to demonstrate each feature.

Gaussian Mixture Model Background Modeling

Implementation of Gaussian Mixture Model (GMM) background modeling written in MATLAB. While computationally intensive with relatively slow execution speed, this code serves as an educational example demonstrating the core algorithm mechanics. Originally developed during the author's participation in SJTU's PRP program, this implementation is no longer actively used in the original project but remains valuable for learning purposes.
