Acquisition of a video image processor for motion analysis

本文的研究重点是运动分析 通过活的有机体或单个细胞， 运动模式图像或录像记录。 CellTrakTM 运动分析系统，其专有的视频处理器，是 请求中的主要工具。 CellTrakTM基于视频 “帧捕获器”技术：视频帧的数字化， 随后对数字化图像进行计算机化分析， 框架. 它的设计是为了追踪 视频记录，然后使用算法分析路径形状 计算速度，方向，转弯频率，路径长度， 以及与运动相关的其他参数。 CellTrakTM将用于 三个不同的研究领域：1）分析社会 蚂蚁觅食行为的相关性; 2）检查趋化性 扇贝精子游动行为与卵源性的关系 引诱剂和受精; 3）调查的作用 特定的膜受体和跨膜离子通量 草履虫的化学感受行为 所要求的设备还 包括静态图像处理器软件附件（BioscanR OptimasTM），将与CellTrakTM结合使用， 低对比度视频图像的分析，或者当对比度 增强预处理是必要的， 可以获得移动。

The studies in this proposal are focused on the analysis of motion by living organisms or individual cells either through live video image or videotaped records of movement patterns. The CellTrakTM motion analysis system, with its proprietary video processor, is the primary instrument in the request. CellTrakTM is based on video "frame-grabber" technology: digitization of the video frames and subsequent computerized analysis of the digitized images in a time framework. It has been designed to trace paths of movement from video records and then analyze the path shapes using algorithms that calculate speed, direction, frequency of turning, path length, and other parameters related to motion. CellTrakTM will be used in three distinct areas of research: 1) to analyze the social correlates of foraging behavior of ants; 2) to examine chemotactic swimming behavior of scallop sperm in relation to egg-derived attractants and fertilization; 3) to investigate the role of specific membrane receptors and trans-membrane ion fluxes in chemosensory behavior of Paramecium. The requested equipment also includes a static image processor software accessory (BioscanR OptimasTM) which will be used in conjunction with CellTrakTM for the analysis of low-contrast video images or whenever contrast enhancement preprocessing is necessary before accurate analysis of movement can be obtained.
