Modern C++23 for image processing: memory management, design patterns, CUDA, and OpenCV.

Advanced Programming with Modern C++ 23 for Image Processing

Key Topics

Memory Management

• Call by value (stack) vs call by reference (heap)
• Stack: LIFO, compile-time, 8MB limit, fast
• Heap: manual management, runtime, dynamic, slower
• Tools: valgrind, fsanitize

Design Patterns (Gang of Four)

Creational (5): Factory method, Abstract factory, Builder, Prototype, Singleton Structural (7): Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Proxy Behavioral (12): Chain of responsibility, Command, Mediator, Observer, Interpreter, State, Strategy, Template method, Visitor, Iterator, Memento, Null-object

Smart Pointers

• std::unique_ptr — exclusive ownership
• std::shared_ptr — shared ownership
• std::weak_ptr — non-owning reference
• Rule of five for custom memory management

Compilation

• CUDA Jetson: nvcc -std=c++14 -arch=sm_62 -o main.run main.cu
• C++20 modules: clang++ -std=c++2a -c file.cpp -Xclang -emit-module-interface -o file.pcm

OpenCV C++ Tips

• cv::Mat is a smart pointer — use .clone() for deep copy in vectors
• imagesVector.push_back(imageMat.clone());
