Description: Flood Fill is a fundamental algorithm in image processing used to determine the area connected to a given node in a multidimensional array, such as a digital image. This process involves identifying and filling contiguous regions of pixels that share similar characteristics, such as color or intensity. The algorithm starts at an initial pixel and explores its neighbors, expanding through adjacent pixels that meet a specific criterion, like a color range. This method is essential for tasks like image segmentation, where the goal is to separate different objects or regions within an image. Additionally, flood fill can be used to remove noise in images, fill gaps in objects, and enhance the visual quality of processed images. Its implementation can vary, utilizing techniques such as depth-first search (DFS) or breadth-first search (BFS), depending on the complexity and requirements of the processing. The efficiency and accuracy of flood fill are crucial in applications requiring detailed image analysis, such as in medicine, computer vision, and robotics.
