Examples
- Moreover , experimental results have proved that the method is robust enough to some image degradation process such as cropping , jpeg compression and sharpening etc . embedded zerotree wavelet coding ( ezw ) algorithm , it is found that this algorithm does not make full use of the properties of human visual system ( hvs ) to eliminate visual redundancy
实验证明，该方法对剪裁、 jpeg压缩和锐化等图象退化处理均具有一定的抵抗力，是一种行之有效的水印嵌入方法。本文在对零树编码方法研究的基础上，针对零树编码方法没有充分利用hvs特性来有效消除视觉冗余的缺点，提出了一种基于小波系数的零树编码方案。 - It is difficulit to construct a strong " zero - watermark " because " zero - watermark " is weaker than the traditional watermark . the geometric invariant which is produced by fourier - mellin is computed and some of them are taken as " zero - watermarks " . the experimental results show that our " zero - watermark " is effective and robust
本文“零水印”构造算法是基于fft和lpm来提取几何不变量，并选取一部分作为零水印，实验结果表明在经历了旋转变换、平移变换、缩放、 jpeg压缩、裁剪、涂改和锐化等攻击仍然能将“零水印”提取出来。 - The importan charateristics of wat902h camera and pci 500 camera and methods of capturing video are also included in this paper . imaging computer outside submarine can transfer data between control computer in the submarine by w2k ' s tednal service with highspeed . due to specific charaeristics of undersea optical imaging , underwater imaging processing technique fall into two categoriesfhardware and software , hardware are the design of the lenses used in waer and the choice of high - quality ccd caxner4the other is compllter digital irnage processing , that is mainly gray - level boformation and image sharpening . underwater image - processing software is designed on the basis of image processing on windows avi digital video file
由于水下光学成像的特殊性，水下图象处理技术应该包括硬件和软件两个方面，硬件即水下专用成像镜头的设计与高性能的ccd选择，后期图象处理软件是利用计算机数字图像处理技术提高水下拍摄图象的质量，处理方法主要有灰度变换和锐化处理；实现了对windowsavi数字视频文件文件的图像处理技术，并在此基础上完成了水下电视系统图像处理软件的设计。 - The function of actuation board is to carry on the value filter and peaked processing for the numeral video signal , the enhancement quality of image displaying and save the video signal which has been processed to two groups of rams , then in accordance with the structure of led displaying screen and the characteristic of demonstration , it will read out data selectively and carry on the gradation pulse - duration modulation to give the display panel by the series monolithic integrated circuit ep1c6 of altera corporation
驱动板的功能是利用altera公司cyclone系列单片机ep1c6 ,对数字视频信号进行中值滤波和锐化处理,增强图像的显示质量,并将处理后的视频信号存储到两组ram中,再按照led大屏幕的结构和显示特点,有选择的将数据读出,并进行灰度脉宽调制输出到显示板。
