基于贝叶斯框架融合深度信息的显著性检测

摘要

In the complex background, the traditional saliency detection methods often encounter the problems of unstable detection results and low accuracy. To address this problem, a saliency detection method fused depth in-formation based on Bayesian framework is proposed. Firstly, the color saliency map is obtained by using a variety of contrast methods which includes global contrast, local contrast and foreground-background contrast, and the depth saliency map is obtained by using the depth contrast method based on the anisotropic center-surround difference. Secondly, using the Bayesian model to fuse the color-based saliency map and the depth-based saliency map. The experimental results show that the proposed method can effectively detect the salient targets under complex back-ground and achieve higher detection accuracy on the published NLPR-RGBD dataset and NJU-DS400 dataset.%复杂背景下,传统显著性检测方法经常遭遇检测结果不稳定和准确率低的问题.针对这些问题,提出一种基于贝叶斯框架融合深度信息的显著性检测方法.首先利用全局对比、局部对比和前景背景对比方法获取颜色显著图,并利用非均质中心-邻居差异的深度对比方法获取深度显著图.其次采用贝叶斯模型融合颜色显著图和深度显著图,获得输出显著图.实验结果表明,本文的方法能有效检测出复杂背景下的显著目标,并在公开的 NLPR-RGBD 数据集和NJU-DS400数据集上取得较高检测精确度.
