MATLAB makes image processing easy and powerful using the Image Processing Toolbox. You can perform operations like image enhancement, filtering, segmentation, edge detection, object tracking, and more.

Here’s a basic workflow:

Read the image:

Convert to grayscale (if needed):

Apply filtering (e.g., Gaussian blur):

Detect edges (e.g., Canny method):

Segment objects using thresholding or region growing:

Label and count objects:

MATLAB also supports:

Real-time image acquisition (e.g., webcam input)
Image classification using deep learning (CNNs)
Feature extraction (e.g., corners, blobs, textures)
