Microscopy Image Stitching Optimization
Revolutionizing Atomic Force Microscopy Stitching with Bi-Channel AI
Traditional microscopy image stitching often fails with feature-sparse images or complex transformations, leading to erroneous scientific analysis. Our novel bi-channel aided method leverages auxiliary image channels (e.g., amplitude, phase, or differential) to extract more reliable features, drastically improving stitching accuracy and enabling seamless high-resolution composites even with limited overlap. This advancement is critical for applications in materials science, biology, and medical diagnostics, preserving crucial physical insights.

Microscopy imaging is essential but limited by field-of-view, necessitating image stitching. However, existing methods face significant hurdles. Feature-based techniques struggle with feature-sparse images, common in AFM data, and can't always account for all transformations like rotations and scaling, often leading to misalignment. Fourier-based methods are fast but only handle translational shifts. Even advanced tools like MIST, Stitch2D, and neural network approaches still leave artifacts or fail entirely when overlap is minimal or features are unevenly distributed. These limitations compromise data integrity and downstream analysis.
Our innovative bi-channel method overcomes these limitations by leveraging additional, correlated image channels. Instead of relying solely on the primary topographical image (often feature-sparse), we utilize secondary channels—like amplitude, phase, or even the x-axis differential of the topographical image—which often contain richer, more detectable features. These features are used for robust feature detection, matching, and camera pose estimation. The derived transformation matrices are then applied to the primary topographical images, ensuring precise alignment and seamless blending, even with limited (10%) overlap and complex transformations.
We validated our method on challenging AFM datasets, including Pantoea sp. YR343 biofilms and PTO thin films. In scenarios where traditional tools like Stitching and Stitch2D failed, and MIST produced significant seam lines and misalignments, our bi-channel approach consistently delivered seamlessly stitched, high-resolution composites. By exploiting the richer feature sets in auxiliary channels, we achieved up to a 7.3x increase in detected features, leading to superior alignment. This method significantly enhances the accuracy of large-area microscopy analysis, preventing false interpretations and accelerating scientific discovery across various fields.

Case Study: Biofilm Assembly (Pantoea sp. YR343)
In a critical study of Pantoea sp. YR343 biofilm assembly using AFM, our bi-channel method excelled where others failed. Traditional tools like Stitching and Stitch2D were unable to align images with just 10% overlap, while MIST, though completing the stitch, introduced visually undesirable seam lines and misalignments. By leveraging amplitude channels for feature detection, our approach delivered seamless, artifact-free composites, preserving the integrity of the crucial morphological details for accurate biological analysis and discovery.
