对于普通用户来说，摄影摄像都是一件简单的事情，最多在拍摄后将数码影像导进电脑而已。但使用D80和EOS 5D Mark Ⅲ的摄影师，所考虑的就不仅仅只是相机这个最基本的摄影工具，如何最大限度发挥其卓越的成像性能才是至关重要的——配...对于普通用户来说，摄影摄像都是一件简单的事情，最多在拍摄后将数码影像导进电脑而已。但使用D80和EOS 5D Mark Ⅲ的摄影师，所考虑的就不仅仅只是相机这个最基本的摄影工具，如何最大限度发挥其卓越的成像性能才是至关重要的——配合尽可能高级的镜头、闪光灯以获取高画质，在享受超高像素带来的快感时，你的记忆卡、读卡器、数码伴侣、硬盘以及电脑性能都应该升级了。展开更多

The system segments the CT brain images into three partitions, i. e., abnormalities, cerebrospinal fluid （CSF）, and brain matter. Our approach consists of two phase-segmentation methods. In the first phase segmentation, k-means and fuzzy cmeans （FCM） methods were implemented to segment and transform the images into the binary images. Based on the connected component in binary images, a decision tree was employed for the annotation of normal or abnormal regions. In the second phase segmentation, the modified FCM with population-diameter independent （PDI） segmentation was applied to segment the images into CSF and brain matter. The experimental results have shown that our proposed system is feasible and yield satisfactory results.展开更多

This shall be done under the following categories of analysis： snapshot, organization, socialization, reception, privacy, and copyrights in digital photography. The study explores the forms of digital photography production, technical problems of photographic management and the final uses that digital photographers give to their photos in terms of web tools 2.0, mobile telephones and social networks. Digital photography technology, compact cameras, mobile phones with cameras, specialized websites in photography and the lnternet generate new forms of production and emerging styles of digital photographic socialization. The study is carried out using a defined sample of university students, those digital natives who create and use digital photography.展开更多
