 | Find Edges Concepts |
The Find Edges step searches for edges along a one-dimensional region of interest, such as a line, broken line, or curve. Edges are typically characterized by sharp transitions in pixel intensities.
The step locates an edge based on its edge strength. You can study the Edge Strength Profile to determine the edge strengths along the region of interest. A peak in the profile indicates that an edge is present at that position along the region of interest. The strength of that edge is given by the amplitude of the peak.
The default region of interest tool is a line. You can examine different path profiles of the image using the broken line tool or the freehand tool. Also, you can locate edges along multiple regions of interest.
