Face Recognition
Face recognition is a computer vision technology that identifies or verifies individuals by analyzing facial features in images or video. It is used in security systems, phone unlocking, and photo organization.
Understanding Face Recognition
Face recognition is a computer vision application that identifies or verifies a person's identity by analyzing facial features from images or video. Modern systems use deep learning architectures, typically convolutional neural networks, to generate an embedding for each face that encodes its unique characteristics in a high-dimensional vector space. Matching is then performed by measuring the distance between embeddings. Face recognition powers applications like smartphone unlocking, airport security, photo organization, and surveillance systems. The technology has raised significant ethical concerns around privacy, racial bias in training data, and consent, making explainable AI and fairness auditing important companions to deployment. Techniques such as data augmentation with varied lighting, angles, and demographics help improve model robustness. Advances in few-shot learning enable face recognition systems to work with limited reference images per individual.

Bounding Box
A bounding box is a rectangular border drawn around an object in an image to indicate its location and extent. Bounding boxes are the primary output format for object detection models.
Computer Vision
Computer vision is a field of AI that enables machines to interpret and understand visual information from images and videos. Applications include facial recognition, autonomous driving, medical imaging, and augmented reality.
Image Captioning
Image captioning is the AI task of generating natural language descriptions of images. It requires both visual understanding (computer vision) and text generation (NLP) capabilities.
Image Classification
Image classification is the computer vision task of assigning a label to an entire image based on its visual content. Deep learning models like ResNet and Vision Transformers achieve near-human accuracy on this task.
Image Segmentation
Image segmentation is the process of partitioning an image into meaningful regions or classifying each pixel into a category. It is used in medical imaging, autonomous driving, and satellite analysis.
Instance Segmentation
Instance segmentation is a computer vision task that identifies each object in an image and delineates its exact pixel boundary. Unlike semantic segmentation, it distinguishes between individual instances of the same class.
Masked Autoencoder
A masked autoencoder is a self-supervised learning method that masks random patches of an image and trains the model to reconstruct them. It has proven highly effective for pre-training vision models.
Neural Radiance Field
A Neural Radiance Field (NeRF) is a deep learning method that represents 3D scenes as continuous functions, enabling photorealistic novel view synthesis from 2D images. NeRFs have transformed 3D reconstruction and rendering.
