This ImageJ plugin demonstrates the use of the HoughTransformLines class for detecting straight lines in images (see Sec. 12.2 of [1] for details). It expects a binary input image with background = 0 and foreground (contour) pixels with values > 0. A vector overlay is used to display the detected lines. If no image is currently open, the plugin optionally loads a suitable sample image.
