Implementation of image inpainting suitable for large damaged areas. This algorithm utilizes exemplar-based image inpainting for region filling and object removal, operates in CIE Lab color space for improved color perception alignment, and was originally published in IEEE 2004. The MATLAB implementation includes priority-based patch selection and texture synthesis mechanisms.
Calculate Signal-to-Noise Ratio (SNR) using MATLAB, implementing the formula as signal energy divided by noise energy
This algorithm implements fundamental matrix computation for stereo vision cameras in MATLAB 2008b environment. It includes four main functions: main, sevenPoint, eightpoint, and eightpoint_norm. The main.m serves as the program entry point, handling experimental data generation and loading, calling the three fundamental matrix computation functions, and visualizing the results. The sevenPoint.m implements the 7-point algorithm, eightpoint.m uses the standard 8-point algorithm, while eightpoint_norm.m performs data normalization before applying the 8-point method for improved numerical stability.
