Abstract

fetched live from OpenAlex

A 2D to 3D video conversion scheme based on color segmentation and motion information is presented in this paper. Optical flow with initial input from MPEG4 is employed to acquire high quality motion information, which can guarantee better depth information; color segmentation in this scheme divides the reference frame into homogeneous regions and restricts the objects boundaries more accurately; based on the divided regions, the depth values from the motion vectors are used to derive a group of depth plane by plane estimation. The experimental results show that our scheme can provide high quality depth map with accurate objects' boundaries.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
