  Dual-Initialization Dense Flow and Scatter-Blur-Decay Boundary Correction for Self-Calibrating Aerial Image Mosaicing
  Author(s): Greg Passmore*
  
  This paper presents a complete pipeline for constructing seamless mosaics from pairs of overlapping aerial photographs captured by uncalibrated consumer-grade drone cameras. The system integrates multi-scale normalized cross-correlation for coarse- to-fine tile registration, six-parameter affine Lucas-Kanade tracking for per-tile local deformation estimation, Brown-Conrady lens distortion fitting via grid-search-initialized weighted least squares, dense Lucas-Kanade optical flow on an 8-pixel grid with iterative dual-initialization refinement, hierarchical Catmull-Rom bicubic upsampling to per-pixel resolution, dynamic- programming seam finding with flow-magnitude-weighted cost, Laplacian pyramid multi-band blending, and a Gaussian- smoothed boundary correction field that eliminates Voronoi discontinuity artifacts. The pipeline introduces several novel methods and combinations: (1) a .. Read More»
