Detailed Documentation
The MATLAB code developed for this project handles fingerprint image preprocessing through binarization and thinning operations. After compilation verification, the code demonstrates correct functionality. This implementation processes fingerprint images by converting them into binary format using adaptive thresholding techniques, followed by morphological thinning algorithms to skeletonize the ridge patterns. Key functions include grayscale conversion, Otsu's threshold selection for binarization, and Zhang-Suen thinning algorithm for ridge refinement. The processed results effectively extract characteristic fingerprint features while maintaining structural integrity through pixel connectivity preservation during thinning operations.
