Studying on a pixel-level multisensor image fusion algorithm

摘要: 該文給出了一種像素級多傳感器圖像融合算法,并將其應(yīng)用于不同波段SAR圖像的融合。該算法先用基于卡爾曼濾波的圖像融合技術(shù)得到一幅灰度融合圖像,再用不同的RGB顏色通道分別表示灰度融合圖像以及原圖像中增強后的細節(jié),最終得到一幅彩色融合圖像。仿真結(jié)果表明,用此算法得到的彩色融合圖像包含更多的細節(jié),可辨識性強。

Abstract: A pixel-level multisensor image fusion algorithm is proposed in this paper, and applied to fusion two SAR images of different frequency. A gray fusion image is firstly obtained using image fusion technique based on Kalman filter. Then, the gray fusion image, the enhanced details from two original images, are sent to RGB channels. A color fusion image is showed finally. The color fusion image includes more details, and the scene in it is easy to recognize. -
