HitoMi-Cam: A Shape-Agnostic Person Detection Method Using the Spectral Characteristics of Clothing

arXiv — cs.CV•Thursday, November 13, 2025 at 5:00:00 AM

The introduction of HitoMi-Cam marks a significant advancement in person detection technology, particularly in scenarios where traditional CNN-based methods falter due to shape dependency. By leveraging the spectral reflectance properties of clothing, HitoMi-Cam achieves a remarkable processing speed of 23.2 frames per second and an average precision of 93.5%, far exceeding the best performance of CNN models at 53.8%. This method not only demonstrates practical viability on resource-constrained edge devices but also maintains a minimal occurrence of false positives, making it suitable for real-time applications. The study positions HitoMi-Cam as a complementary tool rather than a replacement for CNNs, particularly in unpredictable environments, thus broadening the scope of person detection capabilities.

Robust inverse material design with physical guarantees using the Voigt-Reuss Net

PositiveArtificial Intelligence

A new method for mechanical homogenization has been proposed, utilizing a spectrally normalized surrogate that incorporates physical guarantees. This approach leverages the Voigt-Reuss bounds and employs a Cholesky-like operator to create a symmetric positive semi-definite representation. The method has been tested on a dataset of stochastic biphasic microstructures, achieving near-perfect fidelity in isotropic projections with R² values exceeding 0.998. The median relative Frobenius error was approximately 1.7%.

Neural Network-Powered Finger-Drawn Biometric Authentication

PositiveArtificial Intelligence

A recent study published on arXiv investigates the use of neural networks for biometric authentication through finger-drawn digits on touchscreen devices. The research involved twenty participants who contributed a total of 2,000 finger-drawn digits. Two CNN architectures were evaluated, achieving approximately 89% authentication accuracy, while autoencoder approaches reached about 75% accuracy. The findings suggest that this method offers a secure and user-friendly biometric solution that can be integrated with existing authentication systems.

YCB-Ev SD: Synthetic event-vision dataset for 6DoF object pose estimation

PositiveArtificial Intelligence

The YCB-Ev SD dataset has been introduced as a synthetic collection of event-camera data aimed at enhancing 6DoF object pose estimation. Comprising 50,000 event sequences, each lasting 34 ms, the dataset is generated from Physically Based Rendering (PBR) scenes of YCB-Video objects. This initiative addresses the lack of comprehensive resources in event-based vision, employing a methodology aligned with the Benchmark for 6D Object Pose (BOP) to improve pose estimation performance through advanced encoding techniques.
