Dual-correlation transformation for image stitching
Bibliographic record
Abstract
In order to obtain accurate and stable image stitching results, we propose a stitching method for two images captured from different viewpoints based on correlation transformation. Aiming at resolving the limitation of the projective transformation that is commonly used in image stitching, a transformation called dual-correlation transformation is proposed in this paper. First, the estimation result of the fundamental matrix is calculated by the direct linear transformation based on the corresponding points in two images. Second, according to the presented dual-correlation transformation, a pair of correlation transformation matrices that are needed for dual-correlation warp can be obtained to realize the correspondence of each pixel in different images. Up to this stage, the method of image stitching based on transformation matrices has been accomplished. Finally, an optimization method based on factorization is especially proposed to solve the discontinuity problem that may occur in the dual-correlation warp. The experimental results and analyses show that the proposed method can achieve more accurate and natural stitching effects and has less computing time of the images in separate scenes compared with other similar methods.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
