敦煌研究院藏王子云、何正璜夫妇敦煌资料目录

1942年6月—1943年5月,王子云率西北艺术文物考察团在敦煌进行了古迹拍摄、壁画临摹、文物收集等工作。1991年,王子云家属向敦煌研究院捐赠当年绘制的崖面全景图1幅;2000年又捐赠壁画临品41幅、西北写生5幅、1953年拍摄的新疆石窟照片168张;本馆还藏有1953年王子云临摹的克孜尔壁画2幅。本文对其中44件敦煌、克孜尔石窟资料和5幅西北写生资料进行了整理。

基于SVD和直方图的JPEG同幅图像篡改盲检测算法

首先分析了基于小波变换和奇异值分解方法对同幅图像拼接篡改检测的缺点,结合相关重要的思想,构建了一种改进算法,该算法运用SVD提取图像块特征,并采用偏移频率的直方图来确定阈值。在仿真实验中,通过运用三种算法对图像篡改进行检测,对比结果表明,文章所提算法对同幅图像单次篡改和多次篡改均有更好的检测效果,而且通过修改图像的质量因子的实验进一步证实了该算法具有一定的鲁棒性。     

关于照片《毛泽东在读书》

人民版高中《历史》必修三第72页有一幅《毛泽东在读书》，标注是拍摄于1960年。然而这一时间可能有误。     

基于拟合的亚像素边缘检测的算法比较

针对传统的边缘检测算法精度不高,提出了基于不同核函数的最小二乘拟合的亚像素边缘检测算法。采用Canny算子对图像边缘进行粗定位,再以基于梯度幅值拟合的高斯函数与基于灰度值拟合的反正切函数和双曲正切函数作为拟合核函数,对一幅拍有标准量块图像的边缘进行检测,结果表明该算法能够有效的进行亚像素边缘检测。     

不同颜色分量对图像分割结果的影响

为了提高图像分割质量,分析了RGB颜色模型下3种颜色分量对花卉图像分割结果的影响。根据花卉目标的颜色特征,在RGB颜色模型下分别提取花卉图像的R分量、G分量、B分量,采用FCM算法分别对3个分量进行图像分割,并对十多幅自然场景下拍摄的不同颜色花卉图像进行分割实验。结果表明,针对合适的色彩分量进行图像分割可以获得更好的分割效果。     

"外师造化,中得心源"--谈如何拍好风光照片

本文从拍摄手法、拍摄角度、拍摄器材的运用、美学因素的渗透等八个方面对如何拍好优秀风光照片作了全面详细的介绍,提出一幅好的摄影作品既要“外师造化”,又要“中得心源”。     

微格教学中电教人员的素质培养

1.微格教学中电教人员摄像技能的培养 摄像是微格教学过程中的首要环节,课堂的教学情况都要通过摄像机遥控器的操作进行拍摄后,形成一幅幅图像进而组成电教录像片,但它不是一幅幅图像的数量叠加堆积,而是摄像人员根据教学内容的要求,以一定的方法和技巧加工而成的。     

基于校园场景的720°全景图制作

介绍720°全景图制作过程。采用普通手机拍摄60-150幅甚至更多来自同一个场景有重叠的图像,使用PanoramaStudio 2 Pro软件将这些图像拼接成一副在水平和垂直方向上都具有360°视角的高分辨率图像,并利用PS对图像进行后期处理,最后生成球面全景漫游系统。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
