First derivative mask such as Robert, Prewitt, Sobel and Fri-chen are suitable to detect Step EdgesSelect one:TrueFalse

Fri-chen are suitable to detect Step Edges

ow does cv2.goodFeaturesToTrack detect corners?It looks for areas with high gradient magnitude in the imageincorrectIt applies a threshold to the image and detects local maxima in the resulting binary imageIt looks for areas where the structure tensor has a small eigenvalueIt applies a Laplacian of Gaussian filter to the image and detects zero-crossings

Segmentation using Discontinuity Property :•Select one:NoneThis involves detection of  object  in the imageThis involves detection of  isolated  POINTs and  LINEs and   EDGEs  in the image

Low-pass filtering effect           Sensitivity to noise           High computational complexity           Inability to detect diagonal edges

Breadth first search __________a.Scans each incident node along with its children.b. Is same as backtrackingc.Scans all incident edges before moving to other NODE.d.Scans all the nodes in random order.
