Line Profile

Description

Calculates the profile of a line of pixels. Type : polymorphic.

 

Input parameters

 

Image Src : class, type acceptedΒ U8Β and I16.
Line Coordinates : array, specifying the pixel coordinates that form the end points of the line.

Output parameters

 

Line Graph : cluster, contains the line profile with an x-origin at 0 and an increment of 1.

x0 : integer, always returns 0.
dx : integer, always returns 1.
Pixels Line : array, returns the line profile calculated in an array in which elements represent the pixel values belonging to the specified vector.

ROI Pixel Statistics : cluster, contains relevant information about the pixels found in the specified vector.

Min : integer, returns the smallest pixel value found in the line profile.
Max : integer, returns the largest pixel value found in the line profile.
Mean : float, returns the mean value of the pixels found in the line profile.
Std Dev : float, returns the standard deviation from the line profile.
Count : integer, returns the number of pixels found in the line profile.

Global Rectangle : cluster, contains the coordinates of a bounding rectangle for the line in the image.

Left : integer, indicates the x-coordinate of the top-left corner of the rectangle.
Top : integer, indicates the y-coordinate of the top-left corner of the rectangle.
 Right : integer, indicates the x-coordinate of the bottom-right corner of the rectangle.
Bottom : integer, indicates the y-coordinate of the bottom-right corner of the rectangle.
