System object: vision.HoughLines
Package: vision

Output intersection coordinates of a line described by a theta and rho pair and reference image boundary lines




    Note:   Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

PTS = step(H,THETA,RHO,REFIMG) outputs PTS as the zero-based row and column positions of the intersections between the lines described by THETA and RHO and two of the reference image boundary lines.

    Note:   H specifies the System object on which to run this step method.

    The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
