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, and 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

The following images illustrate a few of these examples:

Effective techniques for processing digital images include using algorithms and tools that provide a comprehensive environment for data analysis, visualization, and algorithm development.
