Abstract
The application of images and video has increased significantly in recent years. It is crucial to develop indexing techniques for searching images and video on their content. Due to the lower computational complexity, compressed domain indexing techniques are becoming popular. Among the compression techniques, discrete-wavelet-transform based techiques have become popular because of their excellent energy compaction and multi-resolution capability, and has been adopted in the JPEDG2000 image compression standard. In this paper, an efficient indexing scheme in the JPEG2000 framework is proposed. Here, the information on the numbers of bit-planes in code-blocks is directly extracted from the packet header of a JPEG2000 compressed image without decompressing the bitstream. A vector comprising variance and mean of a few selected bit-planes of the code-blocks is used as the image index. Image retrieval is performed by matching the index of the query and candidate images from the database. Experimental results show that the proposed scheme provides a good indexing performance.

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
