Wavelet Coding for Remote
نویسنده
چکیده
A new algorithm for wavelet compression is presented. This algorithm was developed speciically for the Small Spacecraft Technology Initiative (SSTI) Clark mission which requires 3m ground resolution data to be transmitted down over a relatively slow data link. Hence the data needs to be reduced by at least an order of magnitude, yet has to maintain the high resolution as much as possible. Our algorithm is based on the analysis of the communication channel as a whole starting at the image acquisition and ending at image restoration. The quantization maps for the wavelet coded data are developed using the information theoretical metrics that arise from this particular analysis of the visual communication channel.

Remote Sensing Image Compression using 3D-Oriented Wavelet Transform
Remote Sensing is simply defined as the observation of an object from some distance. By using the observation of object we can collect the information of an object without any physical contact with that object. We present a new technique for the compression of remote sensing images based on oriented wavelet transform. A 3D-Oriented Wavelet Transform (OWT) is introduced for efficient remote sens...
متن کاملRemote Sensing Image Compression Using 3d-spiht Algorithm and 3d-owt
Remote Sensing is the gathering of information about a place from a distance. Such information can occur by sensors or satellite, without making any direct contact with that object. We present a new technique for the compression of remote sensing images based on wavelet transform. This transform has similar complexity as the separable wavelet transform while providing better energy compaction a...
متن کاملStrip Based Embedded Coding of Wavelet Coefficients for Large Images
Wavelet based embedded coders such as EZW and SPIHT require full wavelet transform of the image to be buffered for coding. Further, since the transform coefficients are required to be stored in high precision, the buffering requirements are prohibitively high for large images, such as remote sensing images, space borne images, medical images etc. In this paper we investigate, embedded coding of...
متن کاملEmbedded wavelet-based coding of three-dimensional oceanographic images with land masses
We describe the Wavelets Around Land Masses (WAVAL) system for the embedded coding of 3D oceanographic images. These images differ from those arising in other applications in that valid data exists only at grid points corresponding to sea; grids points that cover land or lie beyond the bathymetry have no associated data. For these images, the WAVAL system employs a 3D lifting wavelet transform ...

In this paper, an improved method of remote sensing image compression based on fractal coding and wavelet domain is...
متن کاملEmbedded L-infinite Constrained Compression of Remote Sensing Data
A new wavelet-based L∞ -constrained embedded image coding technique is proposed in this paper. For any desired distortion bound, the embedded bit stream can be truncated at a corresponding bit-rate, for which the required upper bound on the individual elements of the reconstruction error signal is guaranteed. A lifting-based wavelet transform is employed and exact relations are established betw...
