Quizplus · Accepted Answer

Edge detection was used to uncover the outlines of the objects in the image by detecting the changes in intensity and color between adjacent pixels. Line detection would not be able to differentiate between the different boundaries and features in the image. Luminance detection focuses on brightness levels and would not necessarily uncover the outlines of the objects. Color detection would not remove the full colors of the image, which was the purpose of the processing used in this case.
