Image Transform

Transform methods in image processing

An image transform can be applied to an image to convert it from one domain to another. Viewing an image in domains such as frequency or Hough space enables the identification of features that may not be as easily detected in the spatial domain. Common image transforms include:

Computing the Hough Transform of a Gantrycrane image.
Detecting straight lines using a radon transform.

An effective approach to applying image transforms includes using a comprehensive environment for data analysis, visualization, and algorithm development. See MATLAB® and Image Processing Toolbox™ for more information.
