数字X线摄影测量活体脊柱胸段推算身高

目的建立人脊柱胸段长度推算身高的方法。方法应用数字X线摄影技术（DR）摄制514例中国四川汉族人群的胸部DR片，测其脊柱胸段长度，同时准确测量被研究者身高，对测量获得的脊柱胸段长度与身高数据分组进行线性回归分析，建立胸段长度推算身高的回归方程。结果建立了混合组、男性组、女性组、20—45岁男性组、大于45岁男性组、20～45岁女性组和大于45岁女性组7个回归方程，经显著性检验，均有统计学意义（P〈0．01），复相关系数（R）范围0．834～0．624，回归系数（b）范围0．259～0．389，回归方程估计值的标准误在3．88～4．72cm范围内。结论利用人类脊柱胸段长度推算身高的方法在法医学个人识别中具有重要价值。     

摄影要融入社会——中国优秀摄影画册阿尔卡特大奖评委陈海汶谈平遥国际摄影大展参展参评作品

A photographer-turned-entrepreneur in Shanghai, Mr. then Haiwen has been pursuing the “photography can get a better development only if it involves in society” concept in both his business and photography practice. He is exploring a road, which is complementary, not conflicting, and also embraces photography, society, art and business. Since society is so large whereas photography is so esoteric, photography can not get a great leap forward, he thinks, unless it integrates into society. And it is true that any art form is of no value if it is divested of social moorings and photography must go to market if it wants to engage with society.

体表损伤与瘢痕的三维测量方法应用评估

目的检验结构光三维扫描法和单相机摄影测量法这两种三维测量方法在法医学体表损伤与瘢痕测量中的准确性和可靠性。方法对比分析直尺法、结构光三维扫描法和单相机摄影测量法对86处尸体损伤的测量结果;对比分析结构光三维扫描法、单相机摄影测量法、Photoshop套索像素法、PDF阅读软件法对13处活体模拟块状瘢痕面积的测量结果,并记录所耗时间;以贴纸的已知规格信息作为标准值,比较直尺法、结构光三维扫描法和单相机摄影测量法的测量准确度,计算均方根误差(root mean square error,RMSE);对不同操作者和同一操作者前后3次测量结果的可重复性进行组内相关系数(intraclass correla⁃tion coefficient,ICC)一致性评价。结果两种三维测量方法与直尺法在尸体损伤上测得的结果差异无统计学意义;结构光三维扫描法、单相机摄影测量法、PDF阅读软件法的测量结果和Photoshop套索像素法相比差异无统计学意义,单相机摄影测量法后处理耗时长于其他方法;直尺法测量长距离组(10~40cm)时结果小于标准值,RMSE值结果为结构光三维扫描法<单相机摄影测量法<直尺法;组内和组间的ICC值均大于0.99。结论结构光三维扫描法和单相机摄影测量法均可应用于法医学体表损伤的记录和测量,前者在测量精度及稳定性上表现更优,后者的数据色彩还原度更好,但后处理耗时较长。     

漫步平遥赏民居

There are some 3,800 rectangular courtyards, 387 well preserved, spread out in this small town. These idiosyncratic domestic buildings have more or less retained the slyle of the Ming and Qing dynasties: the outer walls are usually made of grey bricks bound with white lime mortar reaching up to a height of seven or eight yards with no windows but crenellated tops, which gives it an imposing look, iust like a citadel.     

平遥：期待冲出围城的摄影节

Of the various photography festivals in China, the Pingyao International Photography Festival is still the one of the highest professional standard, the most appealing. As a form of visual language, imagery should not get divorced from social reality. If we could invite to the festival more culture researchers, historians, anthropologists, sociologists, and painters, the photography festival would break the boundaries of photography, attrad more audience, have a more enduring life, and meanwhile offer a wider scope of knowledge to photographers.     

在瞬间，为历史定格——国际摄影节平遥古城探幽

The ancient city of Pingyao get familiarized with the world, under the auspices of the festival, which brings Pingyao into the mainstream of the world cultural life but also pushes it to the forefront of history. What we felt viewing each frame of photo is the young Pingyao full of vim and vigor. Pingyao, assuming a new posture, is taking to the stage before the world, like beautiful stage sets decorating the ancient city. And all these will be forever fixed in our eyes and memories.

用计算机对偏角摄影获得的变形图像进行矫正问题的研究

偏角摄影是让光线以一定的角度照射到物体表面同时在对应的反射角的方向上记录物体亮度分布的一种摄影方法。对于偏角摄影得到的变形图像进行矫正的方法一般分两步 :一是把变形图像的像素坐标按照变形图像与标准图像之间的交换函数将其还原为标准图像的坐标 ;二是利用灰度内插法确定矫正后的图像像素的灰度值。
