Abstract
In this paper, a new encryption scheme with three different modes of operations is proposed based on dual space-filling curves (SFSs) and a fractional wavelet transform (FrWT). This scheme is initially proposed for images and then extended to videos. The core idea behind the proposed schemes is to decompose an image/video first by the FrWT followed by the shuffling of each sub-band coefficients by means of a dual SFC. At last, an inverse FrWT is performed to get the encrypted image/video. A reliable decryption process is also proposed to construct the original image from the encrypted image. The experimental results, security and comparative analysis demonstrate the efficiency and robustness of the proposed scheme. Further, this paper also proposes an efficient implementation of an FrWT based on chaotic maps.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
