Satellite On-Board Image Coding using PIRANHA Systematic–DSP
نویسندگان
چکیده
The main requirements of satellite on-board processing are heavy constraints on volume/weight/power consumption, the need for computation power always growing and the necessity for an excellent reliability. In many applications, the main part of the computation power is spent in the front-end processing. That’s why the usual solution is an architecture based on ASICs often associated to a DSP. This leads to a very high integration level but all the disadvantages of the specificity of ASICs are kept : difficulty to implement multi-mode applications, impossibility to authorise algorithm evolution, limitation of re-use, high development cost.

متن کاملWavelet Kernels on a DSP: A Comparison between Lifting and Filter Banks for Image Coding
In this paper we develop wavelet engines on a DSP platform, the target application being image and intraframe video compression by means of the forthcoming JPEG2000 and Motion-JPEG2000 standards. We describe two implementations, based on the lifting scheme and the filter bank scheme respectively, and we present experimental results on code profiling. In particular, we address the following prob...

متن کاملAN UNSUPERVISED SEGMENTATION−BASED CODER FOR MULTISPECTRAL IMAGES (WedAmPO3)
To fully exploit the capabilities of satellite−borne multi−hyperspectral sensors, some form of image compression is required. The Gelli−Poggi coder, based on segmentation and class−based transform coding, has a very competitive performance, but requires some a−priori knowledge which is not available on−board. In this paper we propose a new version of the Gelli−Poggi coder which is fully unsuper...
متن کاملOn the optimization of the satellite imaging chain
In this paper, we focus on the global optimization of the satellite imaging chain. The theoretical analysis of the satellite imaging chain optimization is a difficult problem that needs lot of approximations. In order to consider the complex real satellite imaging chain, we propose to address this problem numerically and we present, based on numerical experiments, techniques to optimize the qua...
