WebThe Hough Transform. The Hough transform is a technique which can be used to isolate features of a particular shape within an image. Because it requires that the desired features be specified in some parametric form, the classical Hough transform is most commonly used for the detection of regular curves such as lines, circles, ellipses, etc.. A … WebWe generally use hough transform to detect straight lines. However, medical images often have interference elements. For example, in this case, the dividing line between the skin and muscles of the neck could be easily misjudged by the computer as part of the white box. That's why hough transform can not be applied directly.
WebDownload BibTex. To detect multiple objects of interest, the methods based on Hough transform use non-maxima supression or mode seeking in order to locate and to distinguish peaks in Hough images. Such postprocessing requires tuning of extra parameters and is often fragile, especially when objects of interest tend to be closely located.
