Abstract

fetched live from OpenAlex

Because of ubiquitous irregularities among texture patterns in real images, texture representation has long been a challenge for image analysis. Approaches such as wavelet transforms that use fixed-sized windows to extract local features are popular for texture identification and classification. However, due to the unawareness of texture scales and boundary locations, those block-based approaches have limited success for image segmentation. In this paper, we present a novel algorithm that tends to generate statistical descriptors that are adaptive to the variation of texture patterns based on a simple rule of pruning and concatenating the approximately repetitive patterns. In the context of image segmentation, the color information that is used by the popular mean shift segmentation algorithm is usually not sufficient for good segmentation performance. We alleviate this problem by first preprocessing the image with the proposed method to generate a "texture map" which then becomes the input image representation for the mean shift segmentation algorithm. The experimental results demonstrate the robustness and effectiveness of the proposed texture representation.

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.
