Image / File Processing System

The fastest way to make money with your photography equipment is to sell it.

Description

The backend serves as a centralized processor and distributor for files used by all systems developed within the division. It stores images and various files directly within the file system, while the corresponding file paths and metadata are securely housed in the database. This structure ensures efficient management and quick retrieval of file information across all applications.

Functions

File Serving

• Provides efficient file serving capabilities, mapping filenames to their corresponding application and additional qualifiers. This ensures seamless file access and management.

Image Processing

• Offers robust image processing capabilities, converting images to a certain format and cropping them to pre-defined sizes. This ensures optimal image quality and performance. For versatility and convenience, multiple copies of an image are saved.

Image-to-Text

• Provide optical character recognition capabilities.

Metadata Endpoint

• Enables seamless metadata management, allowing for the creation, acquisition, and modification of metadata associated with a specific file. This enhances file organization and search functionality, making it easier to find and access the needed information.
