# MATLAB's Image Processing Capabilities

## Introduction

MATLAB is a powerful tool for image processing, allowing you to work with images, manipulate them, and apply various filters and algorithms. In this guide, we'll explore MATLAB's image processing capabilities with sample code.

MATLAB can load and display images easily. Here's how to load an image and display it:

``% Example: Load and display an imageimage = imread('sample.jpg');imshow(image);    ``

## Image Manipulation

You can manipulate images by changing their size, rotating them, or adjusting their contrast and brightness:

``% Example: Resize and rotate an imageresized_image = imresize(image, [200, 300]);rotated_image = imrotate(image, 45, 'bilinear');% Adjust contrast and brightnessbrightened_image = imadjust(image, [0.3, 0.7]);    ``

## Filtering and Noise Reduction

MATLAB provides various filters for smoothing or sharpening images and reducing noise:

``% Example: Apply a Gaussian filterfiltered_image = imgaussfilt(image, 2);  % Standard deviation of 2% Reduce noise with median filterdenoised_image = medfilt2(image, [3, 3]);    ``

## Image Analysis

You can perform image analysis tasks like edge detection and object identification:

``% Example: Edge detectionedges = edge(rgb2gray(image), 'Sobel');% Identify objects in the imagelabeled_image = bwlabel(edges);objects = regionprops(labeled_image, 'Area', 'BoundingBox');    ``

## Conclusion

This guide has introduced you to MATLAB's image processing capabilities. MATLAB is a versatile tool for working with images, and it can be used in various fields such as computer vision, medical imaging, and more. As you gain experience, you can explore advanced techniques and algorithms for image processing.
