Bit-plane based Lossless Depth Map Coding Method

Bit-depth scalable lossless coding for high dynamic range images

In this paper, we propose a bit-depth scalable lossless coding method for high dynamic range (HDR) images based on a reversible logarithmic mapping. HDR images are generally expressed as floating-point data, such as in the OpenEXR or RGBE formats. Our bit-depth scalable coding approach outputs base layer data and enhancement layer data. It can reconstruct the low dynamic range (LDR) image from ...

Studying Platelet-Based Depth Map Coding

The multi-view plus depth (MVD) format is a promising representation approach for 3D and free viewpoint video systems as it allows synthesizing more views at the decoder than those explicitly coded at the encoder. This format represents each view of a visual scene with both texture (array of color pixels) and a depth map which provides information about the 3D scene geometry. Thus, for the tran...

Aggrandize Bit Plane Coding using Gray Code Method

With the increasing demand of technology, existing computer make use of graphics spaciously. Windows based operating system exposed to view the file disk file’s directory graphically. Many applications provide graphical user interface , which it makes to easier to understand or interpret e.g. internet download manager shows the status of downloading a file graphically. Advancement of graphics, ...

Lossless Grayscale Image Coding by Using Higher Order Context Modeling and Bit-Plane Decomposition

A Novel Ram Architecture For Bit-Plane Based Coding

An optimized memory organization has been designed for the hierarchical coding of wavelet subbands. A better economy in time and resources can be accomplished by changing the RAM access pattern and using multiple location access at each clock instant. The bit-planes are distributed along the z-direction and the x − y plane contains 256 × 256 number of memory elements. The memory plane selection...
