  1. Afterwards, in order to decrease the contradiction between the more complex and mass remote sensing image data and relatively slow speed of information extraction, an improved sfim image fusion method is proposed. this modified algorithm is on the base of sfim fusion technique, combines ihs method and sfim method and then replaces the former mean filter by an adaptive weighted mean filter. compared with the results of several common fusion techniques through a set of simulation tests between multispectral images and panchromatic images, it is proved that the new method can get an excellent result for the aim of improving spatial resolution while preserving the spectral information of multispectral images

    論文的主要工作和成果包括：在像素層，論文研究了多傳感器數據融合理論及遙感圖像預處理的過程和步驟，歸納了多源遙感圖像像素層融合的常用演算法，並針對目前遙感數據呈海量化、復雜化這一發展趨勢同遙感信息提取的能力和效率滯后這一矛盾，在sfim演算法的基礎上，將ihs變換與sfim相結合，將原演算法中的均值濾波器改進為自適應加權均值濾波器，提出了一種改進的sfim演算法，通過對一組多光譜圖像和全色圖像的雙傳感器融合模擬對比試驗，證明了該演算法在保持原多光譜圖像光譜信息的同時，能夠有效提高融合圖像的空間分辨能力。
  2. First, it delves into the key technique of eis ? image registration, and presents an effective registration algorithm which is from coarse toprecise and form local to global. second, it applies recursive kalman filtering technique inmotion filtering of registration parameters and makes motion compensation for practical image. finally, it takes advantage of mosaicking to reconstruct undefined regions to avoid theubiquitous information missing and image degradation. this algorithm has high precision as wellas high speed

    首先，對電子穩像中關鍵環節? ?圖像配準技術進行了深入研究，給出一種由粗到精、由局部到全局的高效配準演算法;接著，採用了遞歸kalman濾波技術對配準參數進行運動濾波並對實際圖像進行運動補償;最後，利用了圖像拼接技術進行「無定義區」重建，避免了普遍存在的信息丟失和圖像降質問題。
  3. Holographic data storage is a subject of considerable current and commercial interest. volume holographic storage ( vhs ) has attracted interest because of its potential in high - density and fast parallel readout. photorefractive crystals ( e. g.,
