Abstract

fetched live from OpenAlex

Mammography is a low dose x-ray technique that's used to create an image of the breast. It is an efficient way for early detection of any cancerous changes and malignancy of lumps. Mammographic images are usually archived and in many cases are transferred on internet. Therefore, compression of these images has attracted the attention of many researchers. In this paper an efficient method is proposed for lossless compression of mammographic images. Gradual compression of prediction errors in an iterative manner is the basic idea of the proposed method. The simulation results were compared with standard image compression routines such as JPEG-LS, JPEG2000, JBIG and PNG. The superiority of the proposed method was shown for compression of mammographic images.

Teacher imitation

Not 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.
