Most of existing image retargeting approaches only use color information to help preserve important image content. In this paper, we exploit both color and depth information captured by an RGB-D camera to preserve important regions and maintain background structure. In particular, we introduce a depth-based importance map, such that deformation of the image is guided by this map. This depth-bas...

Based on the background of close coal seam mining in Qianjiaying mine, Tangshan, China, feasibility upper complex underlaying goaf is analysed using roof caving analysis and numerical method. The deformation roadways monitored by field measurement 3D laser scanning. characteristics #5 after 1378P, 2071P, 2072P, 2091P working panels with a depth 39–54 m below are Results show that maximum superi...

Content-aware image retargeting has attracted substantial research interests in the related research community. However, so far there is still no method can preserve important image contents and structure well without introducing deformation. To address this problem, we propose a Saliency & Structure Preserving Multi-operator (SSPM) method. SSPM classifies images into three categories utilizing...

In this paper, we present a novel technique for seam carving of stereoscopic video. It removes seams of pixels in areas that are most likely not noticed by the viewer. When applying seam carving to stereoscopic video rather than monoscopic still images, new challenges arise. The detected seams must be consistent between the left and the right view, so that no depth information is destroyed. Whe...

This paper presents the design and validation of a novel and universal 6D seam tracking system that reduces the need of accurate robot trajectory programming and geometrical databases in robotic arc welding. Such sensor driven motion control together with adaptive control of the welding process is the foundation for increased flexibility and autonomous behavior of robotic and manufacturing syst...

This paper aims to put forward a seamless mosaic method of UAV image for dense urban area, which can effectively avoid seam-line pass through the edge of the building, so as to eliminate the ghosting, dislocation and seam in the image mosaic process. Firstly, the radiation error of UAV image are corrected by Wallis algorithm, and extract the corresponding points from the adjacent images by SIFT...

Three kinds of near-field microscopy imaging mode including SEAM (Scanning electron acoustic microscopy), PFM (Piezoresponse force microscopy) and SPAM (Scanning probe acoustic microscopy) have been developed to investigate domain structures of ferroelectric ceramics, crystals and thin films in our studies. The domain imaging mechanisms are presented individually in three imaging modes. Sub-sur...

We present a novel approach to feature-aware mesh deformation. Previous mesh editing methods are based on an elastic deformation model and thus tend to uniformly distribute the distortion in a least squares sense over the entire deformation region. Recent results from image resizing, however, show that discrete local modifications like deleting or adding connected seams of image pixels in regio...

An Augmented Reality (AR) system integrated in a new developed welding helmet improves the conditions for manual welding. The scene is acquired by a stereoscopic High Dynamic Range CMOS (HDRC) camera system that allows the observance of the welding arc and the environment simultaneously. By image processing, the scene will be enhanced and displayed on a video see through Head Mounted Display (H...
