    The assessment of experimental results from subjective visual effect and objective statistical analysis indicates that the proposed scheme has better performance in preserving the spectral characteristics of the multispectral images,while improving the spatial resolution,than the conventional image fusion methods such as the methods based on HIS(hue-intensity-saturation) transform,PCA,and wavelet transform(WT).

  multispectral
Large aperture static interferential multispectral image compression with motion compensation and region of interest coding
      
To perform better on interferential multispectral image compression, wavelet transform based on motion compensation and region of interest coding and asymmetric zerotree was proposed.
      
Based on radiative transfer theory in vegetation and geometric-optical principles, an analytical physical model for calculating multiangular, multispectral reflectance over a non-random, multiple component vegetation canopy is developed.
      
To test this approach, a series of classifications was undertaken using a multispectral digital aerial image of a six hectare test site and a minimum cost path segmentation.
      
The proposed method only estimates the mean vector and covariance matrix of the high-resolution multispectral (MS) images, instead of assuming the joint distribution between the panchromatic (PAN) image and low-resolution multispectral image.

二滩电站及桐子林电站,是我国计划中拟建的大型水电枢纽工程。在这二个电站所属的雅砻江流域下游及安宁河流域内,均存在着大量的泥石流沟。为确定它们对水库的影响及危害程度,需先研究泥石流的分布、类型及其动态变化规律。为此,我们在工作中将该地区的陆地卫星多光谱扫描磁带,在 STC/I~2S 101数字图象处理系统上用各种图象增强、图象变换及图象分类等方法进行了处理,用它来试作了部分地区的泥石流分布图,经与用航空摄影象片及野外实地调查所得的泥石流分布图进行对照,效果良好。

To monitor the dispersion and dilution performance of a sewage outfall a dye can be injected into the sewage and the resultant plume tracked by boat. In recent years remotely sensed imagery has proved to be a useful adjunct to boat survey as it provides a synoptic view of a plume at an instant which, as a result of tide, wind and current changes, a boat survey is unable to do.The aim of this survey was to use airborne multispectral scanner (MSS) imagery and a methodology of modeling, inversion and accuracy...

To monitor the dispersion and dilution performance of a sewage outfall a dye can be injected into the sewage and the resultant plume tracked by boat. In recent years remotely sensed imagery has proved to be a useful adjunct to boat survey as it provides a synoptic view of a plume at an instant which, as a result of tide, wind and current changes, a boat survey is unable to do.The aim of this survey was to use airborne multispectral scanner (MSS) imagery and a methodology of modeling, inversion and accuracy assessment to estimate and map the concentration of three dyed plumes of sewage. After the radiometric, atmospheric and irradiance correction of the airborne MSS data, a standardised radiance index was highly correlated with dye concentration (r = 0.85, significant at the 99% confidence level). Following inversion and extrapolation of this relationship to all of the airborne MSS data, twenty two plume plots were produced. For a seven-class classification of dye concentration these plume plots had an accuracy of 49-90% at the 95% confidence level increasing to 68-100% at the 95% confidence level for a two-class classification.

为了监测污水排放后扩散和稀释的过程,可在污水里注入染料,利用考察船追踪其羽状扩散痕迹(以下简称痕迹)。最近几年的实践证明,遥感影像是船只调查的有效辅助手段。这是因为遥感影像可实时显示大范围的痕迹,而船只调查,由于潮汐、风和水流变化的缘故,是不能做到这点的。 本文所描述的调查,旨在通过机载多光谱扫描影像和模型化、反演及精度评价等一套方法,对三种染色的下水道污水浓度作出估算与制图。 航空多光谱扫描数据,经过辐射、大气和辐射纠正后,所得的标准化辐射指数与染料浓度密切相关(r=0.85,相关在99%置信度水平上显著)。将这个关系对所有航空多光谱扫描数据进行反演和外推后得到22个痕迹图。作7组分类时,染料浓度的痕迹图,在95%的置信度水平上,达到49-90%的精度;作2组分类时,在95%的置信度水平上,精度提高到68-100%。

In digital image mosaicking, search of seam points is the key procedure. It is usually to be done based on certain criteria to select the seam points row by row. In one-dimensional seam point search algorithm, the horizontal artificial edges are more significant than the vertical. In this article, a two-dimensional seam point searching algorithm is suggested where the grey level differences in the vertical direction are concerned as well as in the horizontal direction. Algorithm for mosaics of multispectral images is also introduced. Experiments show that with the method proposed, the artificial edges in the mosaics can be smoothed effectively.

在计算机图像镶嵌中,两相邻图像间接缝的选择是个关键性步骤。常用的方法是根据某种误差准则来逐行(列)选择接边点。现有的误差准则中存在的问题是水平接边质量比垂直接边的质量差。本文提出用两维接边准则代替原有一维准则,使水平接边与垂直接边质量相当。对多波段彩色合成图像数字镶嵌,提出了在三组图像重叠区加权绝对灰差和图像上用两维准则选择寻找接边点的方法。取得了较好的结果。
