Project Description:
This project focuses on implementing image processing techniques using MATLAB, a powerful computational tool widely used for analyzing and processing images. MATLAB’s Image Processing Toolbox provides a comprehensive set of functions that allow for various image enhancement, manipulation, and analysis operations. The goal of this project is to explore core image processing techniques such as image enhancement, filtering, edge detection, segmentation, and object recognition, all within the MATLAB environment.
The project begins with image acquisition, where images are loaded into MATLAB using functions like imread(). The images are then preprocessed, involving tasks like resizing, cropping, and converting to grayscale to prepare them for further analysis.
Key Techniques Implemented:
-
Image Enhancement: Techniques such as histogram equalization and contrast adjustment are applied to enhance image quality. Filters like Gaussian, median, and average filters are used for noise reduction, sharpening, and improving overall image clarity.
-
Edge Detection: Edge detection is used to identify significant changes in intensity that correspond to object boundaries. Methods like Sobel, Prewitt, and Canny edge detectors are implemented to highlight the edges in an image, which are important for object detection and recognition.
-
Image Segmentation: Image segmentation divides an image into meaningful regions. Thresholding methods, including global and adaptive thresholding, are used to segment objects from the background, aiding in image analysis and feature extraction.
-
Object Recognition: Object recognition techniques such as template matching and feature-based methods (like SURF or SIFT) are used to identify specific objects or patterns within an image.
The project provides a comprehensive pipeline for processing and analyzing images, demonstrating how MATLAB can be utilized for a range of applications, including medical imaging, security, and computer vision. By combining these fundamental techniques, the project allows for effective image analysis and extraction of valuable information, with potential real-world applications in diverse fields.
