A robust object detection approach using boosted anisotropic multiresolution analysis
Bibliographic record
Abstract
In an unconstrained environment, adaptive classifiers produce improved recognition. Fast discrete curvelet transform has recently gained attention due to its ability to capture singularities along curves far away from smooth regions. Therefore, curvelet coefficients contain enhanced representation of image details at different scales and orientations. We propose a new approach for object class detection based on curvelet feature subspace obtained using Kernel PCA (KPCA) and learned using AdaBoost scheme [1]. The first contribution of current paper is a unique representation of an image called curvelet feature subspace that preserves global structure, and supports reliable detection of singularities along curves which play a considerably important role in recognition. Second contribution of our proposed method is an adaptive selection of features obtained using anisotropic style multiresolution analysis for robust object detection of varied inter-class, and intra-class attributes. Our proposed method achieved better detection rate compared to state-of-the-art schemes.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
