Eikonal-based region growing for efficient clustering

摘要
En 中文
We describe an Eikonal-based algorithm for computing dense oversegmentation of an image, often called supeipixels. This oversegmentation respects local image boundaries while limiting undersegmentation. The proposed algorithm relies on a region growing scheme, where the potential map used is not fixed and evolves during the diffusion. Refinement steps are also proposed to enhance at low cost the first oversegmentation. Quantitative comparisons on the Berkeley dataset show good performance on traditional metrics over current state-of-the art superpixel methods. (C) 2014 Elsevier B.V. All rights reserved.
