圈闭类型——一种基于封闭层的新分类方案

已发表的油气圈闭分类方案都是根据圈闭的形成机制确定的.这些方案在模拟勘探中有极大的价值.然而,不同方式形成的圈闭可能具有相同的捕获机制(即圈闭储存石油的方式).本文提出一种通过捕获机制对圈闭进行分类的新方案.定义单封闭层圈闭为在封闭层序底部存在闭合等值线的圈闭;多封闭层圈闭为在单一封闭层(上部封闭层的底界)不存在闭合等值线的圈闭。圈闭类型的二次细分需依据封闭层与密封岩性(如整合、不整合、构造或相变)之间的关系;三次细分则要依据封闭层序本身.圈闭是否有效完全取决于封闭层的性能,而封闭层的性能又是由界面的性质和密封岩性决定的.

Recognition of moving objects using feature signatures

An important application of machine vision systems is the recognition of known three-dimensional objects. A major difficulty arises when two or more objects project the same or similar two-dimensional image, often resulting in misclassification and degradation of system performance. The changes in images which result from the motion of objects provide a source of three-dimensional information which can greatly aid the classification process, but this three-dimensional analysis is computationally complex and subject to many sources of error. This work develops a methodology which utilizes the information derived from the apparent changes in object features over time to facilitate the recognition task, without the need to actually recover the three-dimensional structure of the objects under view. The basic approach is to generate a ``feature signature' by combining the feature measurements of the individual regions in a long sequence of images. The static information in the individual frames is analyzed along with the temporal information from the entire sequence. These techniques are particularly applicable in situations where static image processing methods cannot discriminate between ambiguous objects. Two example implementations are presented to illustrate the application of the techniques of object recognition using motion information.
