For example, attempting to read a pixel 3 units outside an edge reads one 3 units inside the edge instead. Crop / Avoid overlap Any pixel in the output image which would require values from beyond the edge is skipped. This method can result in the output image being slightly smaller, with the edges having been cropped.
This is a critical factor for escaping fast out of the building or to a "safe haven". During an emergency evacuation, people do not immediately react after hearing the alarm signal.

For example, the erosion of a square of side 10, centered at the origin, by a disc of radius 2, also centered at the origin, is a square of side 6 centered at the origin. The erosion of A by B is also given by the expression: A ⊖ B = ⋂ b ∈ B A − b {\displaystyle A\ominus B=\bigcap _{b\in B}A_{-b}} , where A −b denotes the translation ...
GrabCut is an image segmentation method based on graph cuts.. Starting with a user-specified bounding box around the object to be segmented, the algorithm estimates the color distribution of the target object and that of the background using a Gaussian mixture model.
