| 摘 要： | 本文采用图象相关的统计模型对平均绝对差算法捕获概率公式进行了推导,并在此基础上进行了化简,从而得到捕获概率的估计公式.使用四幅不同图象所进行的大量实验结果表明,本文捕获概率的估计值与实验值比较接近,而Johnson公式计算值则误差太大.

| Abstract: | A formula of acquisition probability for MAD algorithm is derived based on an image correlative model and by abandoning the assumption that the image consecutive pixels are independent of each other. The formula derived for calculating acquisition probability is simplified. A large quantity of experimental results with three optical aerial photographs and an infrared remote sensing image show that the acquisition probability evaluation approach proposed is much more accurate than Johnson's method. |
