Overview

DigitalZoom C++ library implements digital zoom using bicubic interpolation provided by the ImageResizer module (SIMD-optimized, no external dependencies). The library supports digital zoom level from x1 to x20. The library depends on VFilter library (provides interface for video filter, source code included, Apache 2.0 license) and ImageResizer library (source code included). The library doesn’t have third-party dependencies to be installed in OS. Additionally test application depends on OpenCV library (version >= 4.5, linked, Apache 2.0 license) to provide user interface. The library uses C++17 standard.
