辐射畸变 meaning in Chinese
radiometric distortion
Examples
- Radiometric correction of images is dealt with in the second part of this paper
论文第二部分实现了图像辐射畸变的校正。 - Due to radiometric and geometric distortions of images from photography , even pictures of the same object are often quite different from each other , which bring a lot of trouble and inconvenience to image identification and mosaic
一般的航空照片上都具有不同程度的几何畸变和辐射畸变，严重影响了实物的本来面貌，使得同一实物在不同照片中的表示很不一致，给照片内容的判读和应用带来了很大的不便。 - Firstly , a radiometric correction algorithm applying local maximum entropy is introduced , and then based on the analysis of current correction algorithm , a much better one is presented , which proved to be effective in the correction of radiometric image distortion
论文介绍了局部最大熵图像辐射校正方法，分析了该算法的优缺点，并对其进行了改进。通过改进的局部最大熵方法实现了图像辐射畸变的校正。 - In the beginning , some general ways of image pretreatment technique are introduced , including geometric correction methods of image , radiometric correction of image and filtering wave and removing noise . video image with strong noises is well restored by a integrated filtering wave methods among some non - linear filtering wave methods , which prepare for the image registration following
论文首先介绍了常用的图像预处理技术，包括几何畸变校正，辐射畸变校正和图像滤波，然后对机载摄像机获取的视频图像进行了校正和综合非线性滤波处理，从而为后续匹配处理做好了准备。 - According to this , we propose a new way to renew the traditional method of subjective image quality evaluation , different to only use mse ( mean square error ) and psnr ( peak signal - to - noise ratio ) to evaluate merely on radiation distortion , and complemented quantitative description on compressed image distortion o it is significant to choose the format of video transferation and measuring precision calculation of tracking and measuring systems based on images
中国科学院长春光机与物理研究所博士学位论文据此提出了不同于传统的仅用均方误差( mse )和峰值信噪比( psnr )来评价图像灰度辐射畸变的新思路，补充了对压缩图像几何畸变的定量描述。这对于基于图像的测量跟踪系统中数字图像传输方式的选择，以及评价压缩解压算法对测量精度的影响有重要意义。
