Vehicle Target Detection Algorithm Based on Improved Faster R-CNN for Remote Sensing Images
Bibliographic record
Abstract
Aiming at the problems that remote sensing image vehicle targets are susceptible to complex background interference, multi-scale differences, and difficulties in detecting small targets, this paper proposes a remote sensing image vehicle target detection algorithm based on improved Faster R-CNN. In this paper, based on the framework of Faster R-CNN, firstly, a multi-scale feature extraction network (EM-FPN) is designed by using the FPN structure and ResNet50 network, so that the network extracts rich target features; secondly, the ECA attention mechanism is introduced, so that the feature extraction network focuses on the target features, suppresses the interference of irrelevant background information, and constructs the multirate dilated convolution module (MDCM) to enhance the network's ability to perceive the contextual information of the target; finally, ROI Align is used instead of ROI Pooling to reduce the feature quantization error. The experimental results prove that the accuracy of the proposed algorithm reaches 88.6%, which can effectively detect vehicle targets in remote sensing images.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
