• Introduction
• Highlights
• New License
• C++14 as the minimum required version of C++. Drop C API.
• (?) Modules
• Named parameters in complex algorithms
• More convenient error reporting and logging. Easier debugging.
• Improved matrix calculus/linear algebra support in OpenCV
• Extended set of basic types; built-in color space information
• Improvements in DNN
• Modular architecture with external DNN backends
• Automatic model loading with caching for samples (at least in Python samples, but preferably in C++ as well).
• Better efficiency of DNN on ARM, NVidia, RISC-V etc.
• Python improvements
• RISC-V support
• State-of-art 3D Module
• Tracking module
