Binary Processing Functions
The following functions are available only with a licensed version of NI Vision.
Use Binary Processing functions on binary and labeled images for applications in which the size, number, or shape of the objects in the image are important. Binary images have only two pixel values, unless you label the image.
 | Note Apply a threshold to a grayscale image to make an image binary. For more information about thresholding an image, refer to imaqThreshold() in the Grayscale Processing section. |
The following table lists the Binary Processing functions. The functions in the Binary Processing class are grouped according to the types of operations they perform. The first column contains the name of the class. The second column contains names of function subclasses. The third column contains names of individual function panels. Each Binary Processing function panel represents one function.
