License Plate Number Recognition Using Image Processing

Using MATLAB for image processing enables license plate number recognition, a technology with substantial practical value. Through image processing algorithms and pattern recognition techniques, license plate numbers can be quickly and accurately identified, finding wide applications in traffic management, security surveillance, and intelligent transportation systems. Key implementation steps typically involve image preprocessing (noise reduction, contrast enhancement), license plate localization using edge detection or color segmentation, character segmentation through projection methods, and character recognition employing template matching or machine learning approaches like convolutional neural networks (CNN). Additionally, image processing technology can be applied to facial recognition, object detection, and image enhancement. Therefore, learning and mastering MATLAB image processing techniques is crucial for professionals working in related fields.
