Compression of Concentric Mosaic with Rebinning of Slits (ross)
نویسندگان
چکیده
Concentric mosaic offers a quick solution for the construction and navigation of a virtual environment. However, the associated huge amount of data presents a heavy burden for its application. In this paper, we propose the rebinning of slits (ROSS) approach for the compression of concentric mosaic. The proposed scheme decorrelates the 3D concentric mosaic data set by rebinning the vertical slits from all captured image shots into a 2D panorama, and then compresses the panorama with a highly efficient still image coder, such as JPEG2000. Unlike typical video coders that use motion compensation to decorrelate multiple frames, the rebinning converts 3D spatial correlation into stronger 2D correlation. Experimental results show that ROSS outperforms MPEG-2 coding of concentric mosaic by an average of 1.0dB.

Smart rebinning for the compression of concentric mosaic
The concentric mosaic offers a quick solution to construct a virtual copy of a real environment, and to navigate in that virtual environment. However, the huge amount of data associated with the concentric mosaic is a heavy burden for its application. A 3D wavelet based compressor has been proposed in the previous work to compress the concentric mosaic. In this paper, we greatly improve the com...
متن کاملCompression of Concentric Mosaic Scenery with Alignment and 3D Wavelet Transform
As a new scene representation scheme, the concentric mosaic offers a quick way to capture and model a realistic 3D environment. This is achieved by shooting a lot of photos of the scene. Novel views can be rendered by patching vertical slits of the captured shots. The data amount in the concentric mosaic is huge. In this work, we compress the concentric mosaic image array with a 3D wavelet sche...
متن کاملVirtual Reality Using the Concentric Mosaic: Construction, Rendering and Data Compression
This paper proposes a new image based rendering technique called concentric mosaic for virtual reality applications. It is constructed by capturing vertical slit images when a camera is moving around a set of concentric circles. Concentric mosaic allows the user to move freely in a circular region and observe significant parallax and lighting changes without recovering the geometric and photome...
متن کامل3-D wavelet compression and progressive inverse wavelet synthesis rendering of concentric mosaic
Using an array of photo shots, the concentric mosaic offers a quick way to capture and model a realistic three-dimensional (3-D) environment. We compress the concentric mosaic image array with a 3-D wavelet transform and coding scheme. Our compression algorithm and bitstream syntax are designed to ensure that a local view rendering of the environment requires only a partial bitstream, thereby e...
متن کاملInteractive browsing of 3D environment over the Internet
In this paper, we describe a system for wandering in a realistic environment over the Internet. The environment is captured by the concentric mosaic, compressed via the reference block coder (RBC), and accessed and delivered over the Internet through the virtual media (Vmedia) access protocol. Capturing the environment through the concentric mosaic is easy. We mount a camera at the end of a lev...
