What is PhotoPrism?

PhotoPrism is an open-source AI photo management tool written in Go, designed to provide users with a decentralized photo storage and organization solution. It allows users to run it on their own hardware, giving them full control over their data without relying on cloud service providers. PhotoPrism features powerful photo classification and search capabilities, leveraging AI technology to automatically recognize people, objects, and scenes in photos. It supports a wide range of file formats, including RAW, JPG, PNG, and video files, and offers facial recognition and geotagging features. Additionally, PhotoPrism includes WebDAV synchronization, enabling users to sync photos across different devices, and provides a convenient touch-based experience on mobile devices.

Key Features of PhotoPrism

• Smart Photo Organization and Search: Automatically recognizes people, objects, and scenes in photos using AI technology, allowing for efficient classification and search.
• Comprehensive File Format Support: Supports JPG, PNG, RAW formats, as well as Live Photos and video files, without the need for additional conversion.
• Facial Recognition: Built-in facial recognition automatically detects faces in photos, allowing users to manually tag and organize them.
• Geotagging: Automatically extracts GPS information from photo EXIF data, displaying the photo's location on a high-definition map.
• WebDAV Sync: Includes a built-in WebDAV server, enabling two-way synchronization with other devices for easy access and management of photos across multiple devices.
• Self-Hosting: Users can deploy PhotoPrism on their own servers or personal computers, offering a personalized photo management service.

Technical Principles of PhotoPrism

• Artificial Intelligence (AI): PhotoPrism uses machine learning algorithms to recognize content in photos, including people, objects, and scenes. The algorithms are based on deep learning models, such as Convolutional Neural Networks (CNN), which analyze image features and perform classification.
• Facial Recognition: Leveraging AI technology, PhotoPrism can detect faces in photos, using facial recognition algorithms to identify and classify different individuals. Users can tag recognized faces for better organization and retrieval.
• Geotagging: Based on EXIF metadata in photos, PhotoPrism extracts GPS information, associating photos with specific geographic locations. This allows users to browse and search photos by location.
• Metadata Extraction: PhotoPrism can read and process EXIF and XMP metadata from photos, which includes detailed information such as the time of capture, camera model, aperture, and exposure settings.
