This repository implements a wide range of image processing algorithms in C++ (with some Python components for license plate recognition). It provides functionalities including contrast enhancement, color space conversion, filtering (median, Gaussian, bilateral), feature detection (edges, corners), image interpolation, haze removal, and artistic effects similar to Photoshop. The architecture is modular with algorithms grouped by category in separate directories. Many files include main() functions allowing them to be compiled and run as standalone demonstrations. The primary external dependency is OpenCV, with some files using OpenMP for parallel processing and Intel intrinsics for AVX optimizations. The license plate recognition system integrates C++ preprocessing with TensorFlow/Keras models in Python for character recognition.
