Lossless Compression of Region Edge Maps Lossless Compression of Region Edge Maps
In this note, we describe a lossless compression technique that has been applied to bitmaps deening regions of images. The results show considerable improvement over previous methods. The basic technique is to use context-based statistical modeling fed into an arithmetic coder.
متن کاملEdge-aware depth motion estimation - A complexity reduction scheme for 3D-HEVC
This work presents the Edge-Aware Depth Motion Estimation (E-ADME), a complexity reduction scheme developed for depth maps coding on 3D High Efficiency Video Coding (3DHEVC). This scheme focuses on obtaining an execution time reduction while keeping a high quality of the encoded depth map. E-ADME starts classifying each encoding depth block as edge or homogeneous. If the block is classified as ...
متن کاملSAR Image Compression with Wedgelet-Wavelet1
Wavelet is well-suited for smooth images, but unable to economically represent edges. Wedgelet offers one powerful potential approach for describing edges in an image. it provides nearly-optimal representations of objects in the Horizon model, as measured by the minimax description length. In this paper, we proposed a multi-layered compression method based on Cartoon +Texture model which combin...
متن کاملCombining Edge Images and Depth Maps for Robust Visual Odometry
In this work, we propose a robust visual odometry system for RGBD sensors. The core of our method is a combination of edge images and depth maps for joint camera pose estimation. Edges are more stable under varying lighting conditions than raw intensity values and depth maps further add stability in poorly textured environments. This leads to higher accuracy and robustness in scenes, where feat...
متن کاملCompression and transmission of depth maps for image-based rendering
We consider applications using depth-based Imagebased rendering (IBR), where the synthesis of arbitrary views occur at a remote location, necessitating the compression and transmission of depth-maps. Traditional image compression has been designed to provide maximum perceived visual quality, and a direct application is suboptimal for depth-map compression, since depth-maps are not directly view...
