Digital Image Processing

Process digital images with computer algorithms

Digital image processing is the use of computer algorithms to create, process, communicate, and display digital images. Digital image processing algorithms can be used to:

• Convert signals from an image sensor into digital images
• Improve clarity, remove noise, and other artifacts
• Extract the size, scale, or number of objects in a scene
• Prepare images for display or printing
• Compress images for communication across a network

You can perform digital image processing in MATLAB with Image Processing Toolbox, which provide digital image processing algorithms, tools, and a comprehensive environment for data analysis, visualization, and algorithm development.
