The gesture recognition has raised attention in computer vision owing to its many applications. However, video-based large-scale gesture recognition still faces many challenges, since many factors like background may disturb the accuracy. To achieve gesture recognition with large-scale videos, we propose a method based on RGB-D data. To learn gesture details better, the inputs are expanded into 32-frame...
Although emotional state recognition from voice has been extensively studied, there is not much effort focusing on the online emotion recognition. Since duration and intensity of emotional experiences change over time it is hard to employ existing static transition models while monitoring emotional states especially in an online setting. To overcome this difficulty we introduce a method which incorporates...
In this paper we propose an automatic urban building extraction method for oblique aerial images. Five steps are included in this method: point cloud generation, grid partition, feature extraction, building detection and building reconstruction. Taking advantages of recent progress in large-scale Structure from Motion (SfM) and Multiple View Stereo (MVS), dense point cloud is generated first. Then,...
In this paper, we propose a saliency detection model for RGB-D images based on the contrasting features of color and depth within a Bayesian framework. The depth feature map is extracted based on superpixel contrast computation with spatial priors. We model the depth saliency map by approximating the density of depth-based contrast features using a Gaussian distribution. Similar to the depth saliency...
An automatic lookup tool, which matches and retrieves similar floorplans from a large repository of digitized architectural floorplans can prove to be of immense help for the architects while designing new projects. In this paper, we have proposed a framework for the matching and retrieval of similar architectural floorplans under the query by example paradigm. We propose a room layout segmentation...
