The magnitude information of the Fourier transform of an image.
Transforms an image from the spatial domain to the frequency domain.
Counterparts of spatial filters in the frequency domain. For images,
frequency information is in the form of spatial frequency.
A set of software instructions executed by a single line of code that may
have input and/or output parameters and returns a value when executed.
The nonlinear change in the difference between the video signal's
brightness level and the voltage level needed to produce that brightness.
Measurement of an object or distances between objects.
A filter similar to the smoothing filter, but using a Gaussian kernel in the
filter operation. The blurring in a Gaussian filter is more gentle than a
smoothing filter.
See gradient filter.
Extracts the contours (edge detection) in gray-level values. Gradient filters
include the Prewitt and Sobel filters.
The brightness of a pixel in an image.
Increases the brightness of pixels in an image that are surrounded by other
pixels with a higher intensity.
Reduces the brightness of pixels in an image that are surrounded by other
pixels with a lower intensity.
An image with monochrome information.
Functions that perform morphological operations on a gray-level image.
