【摘要】 分析了从空间遥感图象的自然背景中提取人造目标的复杂度和可行性，应用基于小波变换下多分辨率分解的特征融合技术，提出了一种从自然背景提取具有多边形外形人造目标的算法。对具典型意义的ＳＡＲ图象的人造目标检测，实验结果证明算法是有效的和有一定推广意义的。更多还原

【Abstract】 A model for computer image generation is given in this paper. Both geometric and illumination modeling can be simulated by prediction and pseudo noise sequence in this model. The generated image of natural scenery, e.g. cloud, water area and grass land, is rich in details which indicate that the model is suitable for computer simulation.更多还原
