, 2009 高光谱图像具有更高的目标二维分辨率和光谱分辨率，是采用高光谱成像技术获得的数据信息。它不仅包含被测物的空间形态信息，还包含了反映其像元的物质成份的精细光谱特性，这种光谱信息可用于地物探测、环境监测、目标识别等多种领域。但是高光谱图像的每个像元都对应几十到几百个波段的灰度值，数据量极其庞大，因此必须对其进行压缩。新一代的静止图像压缩标准---JPEG2000由于采用了小波变换和基于优化截断的嵌入式块编码算法(EBCOT算法)，具有良好的低比特率压缩性能、图像渐进传输、随机访问图像数据、ROI编码 ...

, 1997 １９９２年５月到１０月，我们对养于中国科学院水生生物研究所白豚馆的１头白豚进行了游动和呼吸及其昼夜节律的研究。根据游速测定将其游动分为慢速游、中速游和快速游３类。慢速游为最基本的游动方式，其１天中每小时所占的时间份额无明显的昼夜差异，而中、快速游则白天显著多于夜晚；因此，我们所观察到的白暨豚夜晚运动减缓的节律是中、快速游减少的结果。白豚１天中平均呼吸频率为１０６．０５次／ｈ（１．７７次／ｍｉｎ）。其平均呼吸间隔时间为３０．６２±２４．５５ｓ，范围１．０４—３１６ｓ ...
