The linear Hough transform algorithm estimates the two parameters that define a straight line. The transform space has two dimensions, and every point in the transform space is used as an accumulator to detect or identify a line described by . Every point in the detected edges in the image contributes to the accumulators. The dimension of the accumulator equals the number of unknown parameters, i.e., two, consider… WebThe Hough transform in its simplest form is a method to detect straight lines but it can also be used to detect circles or ellipses. ... The threshold eliminates low accumulators. …
