Multi-view object detection in crowded environments presents significant challenges, particularly for occlusion management across multiple camera views. This paper introduces a novel approach that extends conventional multi-view detection to operate directly within each camera’s image space. Our method finds objects bounding boxes for images from various perspectives without resorting to a bird’s eye view (BEV) representation. Thus, our approach removes the need for camera calibration by leveraging a learnable architecture that facilitates flexible transformations and improves feature fusion across perspectives to increase detection accuracy. Our model achieves Multi-Object Detection Accuracy (MODA) scores of 95.0% and 96.5% on the Wildtrack and MultiviewX datasets, respectively, significantly advancing the state of the art in multi-view detection. Furthermore, it demonstrates robust performance even without ground truth annotations, highlighting its resilience and practicality in real-world applications. These results emphasize the effectiveness of our calibration-free, multi-view object detector.

This study introduces a new technique for generating synthetic faces using eyes-to-face inpainting methods. The proposed method can synthesize a face image using a combination of the eyes of two different individuals and use it as an input for inpainting, demonstrating its vast potential for various applications in biometrics. Despite minor biases in age and gender, our method proved effective in training reliable age- and gender-detection models using the generated datasets. We also addressed the challenge of training face recognition models using synthetic datasets, and the results demonstrated satisfactory accuracy across four benchmark face recognition datasets. This method could be particularly beneficial for underrepresented groups, for whom there is a scarcity of face samples in biometric datasets.
