grayImage = rgb2gray(originalImage);

numClusters = 3; % Adjust based on desired clusters

segmented = imsegkmeans(grayImage, numClusters);


Feature Extraction: Feature extraction is crucial for identifying and characterizing key aspects within an image. MATLAB offers a range of feature extraction techniques, including edge detection using the edge function. The following code snippet demonstrates edge detection using the Sobel operator:

originalImage = imread('your_image.jpg');

grayImage = rgb2gray(originalImage);

edgeImage = edge(grayImage, 'Sobel');

imshowpair(originalImage, edgeImage, 'montage');

Practical Examples: Consider an application in medical imaging, where a physician seeks to identify tumor boundaries within an MRI scan. Filtering can help reduce noise, segmentation can isolate the region of interest, and feature extraction can highlight edges, aiding in precise delineation.
