Feature Matching & Image Registration

Overview

Implemented feature-based image alignment for matching and registering images (image fusion) under geometric transformations.

Responsibilities

• Extracted robust keypoints and descriptors
• Matched features across images
• Estimated transformation using RANSAC

Approach

• Keypoint detection (ORB/SIFT-like)
• Descriptor matching
• Homography estimation
