چکیده
In this paper ,we present an overview of the implementation of navel compound algorithm for efficient low bit rate lossy and ROI lossless Mix Coding of massive three dimensional images. Moreover the compound algorithm can be used for multitasking Remote Sensing field operations and efficient 3-D image transmission applications such as overall image viewing at low bit rate lossy coding , nearly lossless ROI coding of most desired target area as well as efficient low memory storage or transmission/network transfer of such 3-D images with volume reduction technique. In the navel compound algorithm, a modification to the conventional 3D-SPIHT algorithm is implemented with 3D IWT, lossless ROI Coding and observer pre decide image size reduction using Volumetric Interpolation. Comparison to conventional 3-D SPIHT with DWT, the compound algorithm results interpret high PSNR at low bit rate coding and efficient and better perceptive effects in the ROI coded images. Key-words:Compound algorithm, Remote sensing (3-D)images, Volumetric interpolation,3-D IWT, lossy and lossless mix coding, modified 3-D SPIHT, (intelligent) network transfer, low bit rate coding ,ROI coding.

Region of interest coding in volumetric images with shape-adaptive wavelet transform
We evaluated some arbitrary-shape ROI (Region of Interest) coding techniques for three-dimensional volumetric images, and through the observation we propose a flexible ROI coding with efficient compression performance. In arbitrary-shape ROI coding, the object in an image is coded with higher fidelity than the rest of the image, together with the shape information, which indicates the region of...

Selective compression of a medical image (MI) becomes an important task in fields of diagnosis, in solving archiving, and transmission problems. In this paper, a proposed bichannel automatic compression technique for medical image processing (MIP) with ROI is introduced using two approaches. The first approach uses two different compression schemes (lossless and lossy) for inside and outside of...
