Examples
- ( 7 ) mathematical morphology is one of the new subjects studying the structural feature of digital image morphology and fast parallel processing technique . the structural analysis and feature extraction is made by morphological transformation in object image
7 、数学形态学是研究数字影像形态结构特征与快速并行处理方法的理论，是通过对目标影像的形态变换实现结构分析和特征提取的。 - It is appropriate commonly that the resolution of ccd sensor imaging is 1 . 8 times of the pixel dimension , in the mean while the mtf decreases 11 % , because the mtf is bigger , the other parts are easier to be made and the image shows the characterization of the object well . 2
一般情况下取ccd探测器的目标影像分辨力是其像元尺寸的1 . 8倍较为适中，因为这时的mtf数值较大对系统的其它环节的指标压力较小，且图像较好地反映了目标图形的特征，此时其光学调制度传递函数mtf下降了11 。 - If the optical system with ccd sensor is regarded as a spatially invariant linear system , the convolution of point spread function and the object image results in error on theory . since ccd sensor imaging is digital imaging , in this article , the image quality and resolution of the ccd sensor imaging is simulated and analyzed
鉴于ccd探测器成像是数字化成像，所以本文采用计算机仿真和ccd相机模拟成像试验及理论分析的方法对ccd探测器的目标影像的分辨力与ccd像元分辨力的关系及像质进行了研究并获得如下主要结论。 - The relation of tthe ccd sensor imaging resolution and the mtf is gotten . when the mtf of space remote sensing camera is higher and the contrast of object is higher , it can be believed that the resolution of ccd sensor imaging is 1 . 6 times of the pixel dimension , in the mean while the mtf decreases 32 %
通过仿真得到了ccd探测器的目标影像的分辨力与ccd像元尺寸的关系，当航天光学遥感相机的mtf较高(仿真中镜头的mtf = 1 )且目标为高对比度时，得到ccd探测器的目标影像分辨力是其像元尺寸a的1 . 6倍，其光学调制度传递函数mtf下降32的结果。
