摘要:

选择性图像分割需要结合用户输入,通过区分相似类型的目标将图像划分为前景与背景。这类方法通常会在通用分割方法的基础上引入额外约束,但我们证明这往往与关于图像的常见假设不一致。本文提出的方法引入了一种新的拟合项,在实际应用中比Chan-Vese框架更具实用性,其核心思路是定义一个允许背景包含多个不均匀区域的项。我们通过与现有替代方法的对比实验,验证了所提方法的优势,拓宽了这类方法的潜在应用范围。

英文摘要:

Selective segmentation involves incorporating user input to partition an image into foreground and background, by discriminating between objects of a similar type. Typically, such methods involve introducing additional constraints to generic segmentation approaches. However, we show that this is often inconsistent with respect to common assumptions about the image. The proposed method introduces a new fitting term that is more useful in practice than the Chan-Vese framework. In particular, the idea is to define a term that allows for the background to consist of multiple regions of inhomogeneity. We provide comparitive experimental results to alternative approaches to demonstrate the advantages of the proposed method, broadening the possible application of these methods.
