To determine the location and value of individual pixels in an image, use the Pixel Region tool of the Image Viewer app.
To measure distance between pixels, use the Distance tool of the Image Viewer app.
Describes functions that return information about a binary image
This example shows how to create a histogram for an
image using the
To compute standard statistics of an image, use the
This example shows how to calculate the properties of regions in binary images using the Image Region Analyzer app.
To determine the values of one or more pixels in an
image and return the values in a variable, use the
A region in an image can have properties, such as an area, center of mass, orientation, and bounding box.
Describes how to use the
to compute the distance transform of an image
The intensity profile of an image is the set of intensity
values taken from regularly spaced points. To create an intensity
profile, use the
A contour is a path in an image along which the intensity
values are constant. To create a contour plot of a grayscale image,
This example shows how to enhance an image as a preprocessing step before analysis.
