Abstract : in this paper , best estimation of combinatorial prediction is constructed by weights reciprocal variances . then their precisions are compared . random error 、 residuals and predicitons by identical precisions are explained
文摘:文中讨论了在方差倒数权为基础的正权组合预测条件下，最佳估计值的确定及其精度比较；并深入阐明随机误差、残余误差及等精度测量的意义和它们之间的关系。
Prediction algorithm is a most simple one of all methods on images compression . and it explore directly the spectral correlations of hyperspectral images . its method is very simple and easy to be implemented . prediction takes full advantage of the spectral correlations to use transmitted spectral to predict current spectral , then predictive error that original spectral is substracted by predictive spectral is coded . the predictive error is wiped off the spectral correlations , so compression is easier than before
预测技术是最简单的一种方法,它直接探索谱带与谱带之间的相关性,具有算法简单、易于实现的特点。预测技术充分利用图像的相关性,用已传输的值对当前值进行预测,然后对预测值与真实值的差即预测误差进行编码处理。预测产生的残余误差已被去相关,因而比较容易压缩。
