基于差异化点击网络的交互式图像分割技术研究
首发时间:2021-02-23
摘要:深度图像分割技术在多领域承担着重要的作用,比如图像修复、图像理解、内容检索、视频分割等研究领域,但是存在边界分割明显、遮挡错误分割等问题,交互式图像分割技术给了用户很大的操作空间、想象力和自由度,弥补自动图像分割技术的不足。基于点击形式的交互式图像分割以主流深度学习网络为主要架构,网络的输入为RGB图像和交互数据融合输入,用户的点击是不断输入的直到得到满意的结果。在前人的研究中,将所有的点击一视同仁,而从感性上考虑不同的点击交互信息所承担的角色是不同的。本文提出了一种DCN(Differentiated Click Network,差异化点击网络)模型将用户交互数据进行分离提取特征单元,增强图像不同区域的信息权重,从而提高模型的分割精度。DCN模型的有效性在ResNet34、ResNet50和MobileNet网络架构上得到了充分的验证,在GrabCut、SBD和Berkeley公开数据集和wx、wxsod和aliwenyu数据集上取得了不错的效果。

Research on Interactive Image Segmentation based on Differential Click Network
Abstract:Depth image segmentation technology plays an important role in many fields, such as image restoration, image understanding, content retrieval, video segmentation and so on, but there are some problems, such as obvious boundary segmentation, occlusion error segmentation and so on. Interactive image segmentation technology gives users a lot of operating space, imagination and freedom to make up for the shortcomings of automatic image segmentation technology. The interactive image segmentation based on click form takes the mainstream deep learning network as the main architecture, the input of the network is the fusion input of RGB image and interactive data, and the user\'s click is continuously input until satisfactory results are obtained. In previous studies, all clicks are treated equally, while perceptual consideration of different click interaction information plays different roles. In this paper, a DCN (Differentiated Click Network, differential click network model is proposed to separate and extract feature units from user interaction data to enhance the information weight of different regions of the image, so as to improve the segmentation accuracy of the model. The effectiveness of DCN model has been fully verified in ResNet34, ResNet50 and MobileNet network architecture, and good results have been achieved in GrabCut, SBD and Berkeley open datasets and wx, wxsod and aliwenyu datasets.
