Flood Fill Algorithm Implementation in MATLAB

Implementing the flood fill algorithm in MATLAB requires the cvlib_mex support library. cvlib_mex is a comprehensive MEX-function library specifically designed for image processing tasks, containing numerous essential functions and algorithms. The flood fill algorithm implementation typically utilizes functions like cvFloodFill() which performs region filling starting from a specified seed point, with options for connectivity type and color tolerance thresholds. If you haven't installed cvlib_mex yet, you can download it from: http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=12200&objectType=File. After downloading, follow the installation instructions to integrate cvlib_mex into your MATLAB environment. Once installed, you can implement flood fill operations by calling the appropriate MEX functions with parameters including the input image, seed point coordinates, new fill color, and connectivity specifications. The algorithm efficiently fills connected regions by recursively examining neighboring pixels while maintaining boundary conditions.
