In these cases, we have knowledge of the shape and aim to find out its location and orientation in the image. This modification enables the Hough transform to be used to detect an arbitrary object described with its model. WebThe Hough Transform is a global method for finding straight lines hidden in larger amounts of other data. It is an important technique in image processing. For detecting lines in images, the image is first binarised using some form of thresholding and then the positive instances catalogued in an examples dataset. island off tampa bay
