Read Full Article: Lightweight Face Anti-Spoofing Model for Low-End Devices
Faced with the challenge of bypassing an AI-integrated system using simple high-res photos or phone screens, a developer shifted focus to Face Anti-Spoofing (FAS) to enhance security. By employing texture analysis through Fourier Transform loss, the model distinguishes real skin from digital screens or printed paper based on microscopic texture differences. Trained on a diverse dataset of 300,000 samples and validated with the CelebA benchmark, the model achieved 98% accuracy and was compressed to 600KB using INT8 quantization, enabling it to run efficiently on low-power devices like an old Intel Core i7 laptop without a GPU. This approach highlights that specialized, lightweight models can outperform larger, general-purpose ones in specific tasks, and the open-source project invites contributions for further improvements.

Imflow is a newly launched minimal web tool designed to streamline the image annotation process, which can often be tedious and slow. It allows users to create projects, batch upload images, and manually draw bounding boxes and polygons. The tool features a one-shot auto-annotation capability that uses OWL-ViT-Large to suggest bounding boxes across batches based on a single reference image per class. Users can review and filter these proposals by confidence, with options to export annotations in various formats like YOLO, COCO, and Pascal VOC XML. While still in its early stages with some limitations, such as no instance segmentation or video support, Imflow is currently free to use and invites feedback to improve its functionality. This matters because efficient image annotation is crucial for training accurate machine learning models, and tools like Imflow can significantly reduce the time and effort required.
