chface

chface is a command-line utility designed for manipulating and analyzing face images. It offers a range of functionalities for developers and researchers working with facial recognition and analysis tasks. The tool typically operates on image files, allowing users to perform operations such as face detection, landmark extraction, and feature vector generation.

One of the primary uses of chface is to identify the presence and location of faces within an image. It employs algorithms to locate facial bounding boxes, providing coordinates for where faces are found. Beyond simple detection, chface can also pinpoint key facial landmarks, such as the eyes, nose, and mouth. These landmarks are crucial for many subsequent facial analysis operations, including alignment and feature extraction.

The utility can also generate numerical representations of faces, often referred to as feature vectors or embeddings. These vectors capture distinctive characteristics of a face in a compact, mathematical form. Such embeddings are fundamental for tasks like face verification (determining if two faces belong to the same person) and face recognition (identifying a person from a database of known faces). chface aims to provide a flexible and efficient way to integrate these facial processing capabilities into larger software projects or research workflows. Its command-line interface makes it suitable for scripting and batch processing.
