In function floodfill
Webb6 jan. 2024 · Flood fill is an algorithm mainly used to determine a bounded area connected to a given node in a multi-dimensional array. It is a close resemblance to the bucket tool in paint programs. The most approached implementation of the algorithm is a stack-based recursive function, and that’s what we’re gonna talk about next. How does it work? Webb8 jan. 2013 · In this section you will learn different image processing functions inside OpenCV. Feature Detection and Description.

Flood fill, also called seed fill, is a flooding algorithm that determines and alters the area connected to a given node in a multi-dimensional array with some matching attribute. It is used in the "bucket" fill tool of paint programs to fill connected, similarly-colored areas with a different color, and in games such as Go and Minesweeper for determining which pieces are cleared. A variant called boundary fill uses the same algorithms but is defined as the area connected to a given node that … homemaker pots and pansWebb17 juni 2024 · Flood fill Algorithm.
