II. Fundamentals of Image Mosaicing
Here, students learn the foundational concepts needed to understand and perform image mosaicing. It covers key image alignment techniques like feature-based matching and direct alignment, introduces geometric transformations, and explains the importance of accurate blending. This section lays the groundwork for deeper technical discussions that follow.

A. Image alignment techniques
This subsection dives into the methods used to align images accurately, including feature-based approaches using keypoints and direct alignment strategies. It also explains geometric transformations like scaling, rotation, and translation essential for creating a coherent mosaic.

B. Image alignment and blending process
Focusing on the fusion of aligned images, this part explores blending methods to reduce seams and ensure visual smoothness. It also addresses challenges like ghosting, parallax, and color mismatches that often arise during composition.

III. Techniques for Image Mosaicing
This chapter delves into detailed methodologies used in modern mosaicing. It explains keypoint detection, feature descriptors, and matching algorithms, while also exploring pixel-level alignment and transformation techniques like homographies, warping, and blending.

A. Feature-based matching in detail
A thorough look into keypoint-based mosaicing, covering how features like SIFT or ORB are extracted, matched, and used to find image correspondences—even under changes in scale, rotation, or lighting.

B. Direct alignment methods
This part explains how image mosaicing can be done by directly comparing pixel intensities, using correlation or optimization-based approaches. It’s particularly useful for sequences with minor shifts or when feature detection is unreliable.

C. Geometric transformations and homographies
Students learn how to compute and apply homographies to warp images for alignment, followed by various blending strategies that preserve image continuity and realism in the final mosaic.

IV. Advanced Image Mosaicing Methods
This chapter focuses on high-precision and specialized mosaicing methods, including sub-pixel alignment and mosaicing of multispectral or hyperspectral images. It also addresses how to handle dynamic scenes, lighting differences, and complex 3D distortions.

Handling challenging scenarios
This critical subtopic explores the complexities faced when mosaicing images under real-world, non-ideal conditions. It delves into techniques for managing moving objects that can cause ghosting, dealing with varying lighting conditions that disrupt color consistency, and correcting for perspective distortions and parallax effects that lead to misalignment. Learners will gain insights into how to enhance robustness and maintain seamlessness in even the most dynamic or geometrically complex scenes—an essential skill for professionals in surveillance, medical imaging, and autonomous systems.
