This document presents research on offline signature verification using local keypoint features. It discusses existing challenges in offline signature verification like different signature orientations and image noise. The objective is to develop a robust method for offline signature verification that can handle noise, orientation variations, and different writing styles. The proposed method uses Harris corner detection to extract keypoints, and creates a 128-bin feature descriptor for each keypoint. Keypoint matching and classification using KNN is then used to verify signatures. Future work includes implementing the proposed method and improving its robustness to rotations, noise, and ink variations with minimal complexity.
