Get Started with Image Processing Toolbox

Perform image processing, visualization, and analysis

Image Processing Toolbox™ provides a comprehensive set of reference-standard algorithms and workflow apps for image processing, analysis, visualization, and algorithm development. You can perform image segmentation, image enhancement, noise reduction, geometric transformations, and image registration using deep learning and traditional image processing techniques. The toolbox supports processing of 2D, 3D, and arbitrarily large images.

Image Processing Toolbox apps let you automate common image processing workflows. You can interactively segment image data, compare image registration techniques, and batch-process large datasets. Visualization functions and apps let you explore images, 3D volumes, and videos; adjust contrast; create histograms; and manipulate regions of interest (ROIs).

You can accelerate your algorithms by running them on multicore processors and GPUs. Many toolbox functions support C/C++ code generation for desktop prototyping and embedded vision system deployment.

Tutorials

Basic Image Import, Processing, and Export

This example shows how to read an image into the workspace, adjust the contrast in the image, and then write the adjusted image to a file.
Detect and Measure Circular Objects in an Image

Automatically detect circular objects in an image and visualize the detected circles.
Correct Nonuniform Illumination and Analyze Foreground Objects

This example shows how to perform image preprocessing such as morphological opening and contrast adjustment. Then, create a binary image and compute statistics of image foreground objects.
Find Vegetation in a Multispectral Image

Use array arithmetic to process an image with three planes, and plot image data.

About Image Processing

Images in MATLAB

Many images are represented by 2-D arrays, where each element stores information about a pixel in the image. Some image arrays have more dimensions to represent color information or an image sequence.
Image Types in the Toolbox

Image types determine how MATLAB^® interprets data matrix elements as pixel intensity values. The toolbox supports many image types including binary, grayscale, truecolor, multispectral, and label images.
Image Coordinate Systems

Learn how image locations are expressed using discrete pixel indices and continuous spatial coordinates.
