Building a License Plate Recognition Engine in C++ — Part 2: Grayscale Image Preprocessing and Local Contrast Edge Detection

1. 1Load an image and convert it to grayscale using OpenCV
2. 2Generate an integral image to facilitate local contrast analysis
3. 3Apply local contrast edge detection to enhance image regions containing license plate characters
4. 4Extract an edge map from the preprocessed image
5. 5Create a ternary edge image to further refine the edge detection results

Computer vision engineers and developers working on object detection and image processing tasks can benefit from this tutorial to improve their skills in building efficient preprocessing pipelines
