A CNN-Transformer Hybrid for Precise Object Detection in UAV Aerial Imagery
Bibliographic record
Abstract
The proposed hybrid framework in this paper is a deep learning technique to robustly detect objects and classify them in real-time applications and includes the use of Convolutional Neural Networks (CNNs) to capture local features, Transformer blocks to learn the global context, and adaptive feature fusing gating to integrate information to achieve optimal consistency. The proposed architecture uses feature pyramid networks (FPN) combined with path aggregation networks (PAN) to help provide better multi-scale representation and accelerate large and small, as well as rich and weak objects. Broad experiments have been carried out across several benchmark and cross-domain datasets such as indoor detection, agricultural leaf diseases recognition, and X-ray illegal content identification. This proposed model has an mAP@0.5:0.95 of 55.7 percent, a precision of 91-4 percent, and a recall of 88.0 percent, with a speed of 126 FPS on an RTX 4090, out beating state-of-the-art models like YOLOv7, DETR, and RT-DETR. Superior generalization ability is confirmed by cross-domain evaluations, and complementary role of the modules is validated by ablation studies. These findings show that the suggested framework can accomplish a desirable trade-off of accuracy and speed with good results and may be utilized on real-time tasks, e.g., autonomous navigation, industrial inspection, or security monitoring.

How this classification was reachedexpand
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.
