Shape completion is an important task in the field of image processing. An alternative method is to capture the shape information and finish the completion by a generative model, such as Deep Boltzmann Machine. With its powerful ability to deal with the distribution of the shapes, it is quite easy to acquire the result by sampling from the model. In this paper, we make use of the hidden activation of the DBM and incorporate it with the convolutional shape features to fit a regression model. We compare the output of the regression model with the incomplete shape feature in order to set a proper and compact mask for sampling from the DBM. The experiment shows that our method can obtain realistic results without any prior information about the incomplete object shape.
形状补全是图像处理领域中的一项重要任务。一种替代方法是捕获形状信息并通过生成模型(如深度玻尔兹曼机)来完成补全。凭借其处理形状分布的强大能力,通过从模型中采样很容易获得结果。在本文中,我们利用深度玻尔兹曼机的隐藏激活,并将其与卷积形状特征相结合来拟合回归模型。我们将回归模型的输出与不完整形状特征进行比较,以便为从深度玻尔兹曼机采样设置合适且紧凑的掩码。实验表明,我们的方法无需关于不完整物体形状的任何先验信息就能获得逼真的结果。
