line detection and edge detection of images.
process of reducing foreground regions in a binary image.
applying the kernels to the skeletonized image to detect the lines.
edge detection operator that uses a multi-stage algorithm to detect a wide range of edges in images
- Apply Gaussian filter to smooth the image in order to remove the noise
- Find the intensity gradients of the image
- Apply non-maximum suppression to get rid of spurious response to edge detection
- Apply double threshold to determine potential edges
- Track edge by hysteresis: Finalize the detection of edges by suppressing all the other edges that are weak and not connected to strong edges.
