所谓电子报表可以从报表和电子两个方面来理解。报表是由横线和竖线交织成的网络,其中网格单元(Cell)是输入和处理信息的基本单位。Lotus1-2-3Release3.4a和Lotus1-2-3Release4.01的工作表(Worksheet)都有256页,每页工作表都有8192行和256列所组成的2,097,152个单元,所以整个软件提供了536,870,912个网格单元。由于每个网格单元都有页号(分别为A,B,C,AA,AB,……,IV)、列号(分别为A,B,C,AA,AB,……,IV)和行号(分别为1,2,3,……,8192),所以任一单元的位置可由页、列和行的标号组合来确定,…  相似文献

近年来,能插在电脑上使用的玩意儿越来越多,比如数码相机,打印机,扫描仪,游戏杆,读卡器,MP3播放器,无线耳机收发器,微型硬盘等等,数不胜数,随着即插即用功能的出现,在电脑上添加新设备也越来越简单,但新添加的设备会请求使用系统资源,因此添加的设备越多,出现资源冲突的可能性也越高。结果呢?系统可能会变慢,死机,无法启动。  相似文献

A new data abstraction, called Materialization, is introduced to model a situation that occurs frequently in the real world and has important implications for database design. Materialization is the relationship between two entity types, one that represents a conceptual object, for example, a TV Model, and one that represents its corresponding concrete objects, in this case, actual TV Sets. The Materialization construct is formally defined and contrasted with other well-known data abstractions. Its design implications are presented in terms of the entity-relationship model and its translation into a relational model. Guidelines are offered for the proper employment of this relationship in database design methodologies, and a discussion is provided of why this constitutes an important data modeling construct  相似文献

在基于.NET平台的管理信息系统中,面向对象的业务处理和关系数据存储存在着一定的矛盾。在分析.NET平台的数据库处理的技术基础上,设计了一个对象/关系数据库映射模式,并结合这个模式创建了一个通用的数据操作框架CFC,实现了对象/关系数据库映射。CFC框架使软件开发人员能够以面向对象的方法进行对象数据存取,而不必了解后台关系数据库的实现。该框架实际应用到了广东电网公司阳光采购系统。  相似文献

为了实现复杂自然场景中多类目标的识别与分割,本文利用条件概率模型(CM)对目标特征进行建模,融合了纹理特征、纹理环境特征和位置特征,并采用场景类别对各类目标间的相互约束关系进行建模,在此基础上研究基于场景类别的条件概率模型(sCM)在多类目标识别与分割中的应用。本文选用Oliva&Torralba数据库对模型进行实验并与国外其他方法进行了比较。实验结果表明,该算法在多类目标识别与分割中取得很好的结果,在提高总体识别率的同时提高了物体边缘部分识别与分割的正确率,更有效地提高了视觉效果。  相似文献

A pictorial query specification technique that enables the formulation of complex pictorial queries for browsing through a collection of spatially referenced images is presented. It is distinguished from most other methods by the fact that in these methods the query image specifies a target database image in its entirety whereas in our approach the query image specifies the combination of objects that the target database image should contain rather than being treated as a whole image. The query objects are represented by shape features although other features such as color, texture or wavelets could also be used. Using our technique, it is possible to specify which particular objects should appear in the target images as well as how many occurrences of each object are required. Moreover, it is possible to specify the minimum required certainty of matching between query-image objects and database-image objects, as well as to impose spatial constraints that specify bounds on the distance between objects and the relative direction between them. These spatial constraints can also be used to specify other topological relations such as enclosure, intersection, overlap, etc. Each pictorial query is composed of one or more query images. Each query image is constructed by selecting the required query objects and positioning them according to the desired spatial configuration. Boolean combinations of two or more query images are also possible by use of AND and OR operators. A query image may be negated in order to specify conditions that should not be satisfied by the database images that are retrieved successfully. In addition, a capability is provided to specify whether the same instance of an object is to be used when it appears in more than one of the query images that make up the pictorial query, or whether two different instances are allowed. Several example queries are given that demonstrate the expressive power of this query specification method. An algorithm for retrieving all database images that conform to a given pictorial query specification is presented. The user interface for using this pictorial query specification method to browse the results in a map image database application is described and illustrated via screen shots.  相似文献

Transformer-based architectures have shown encouraging results in image captioning. They usually utilize self-attention based methods to establish the semantic association between objects in an image for predicting caption. However, when appearance features between the candidate object and query object show weak dependence, the self-attention based methods are hard to capture the semantic association between them. In this paper, a Semantic Association Enhancement Transformer model is proposed to address the above challenge. First, an Appearance-Geometry Multi-Head Attention is introduced to model a visual relationship by integrating the geometry features and appearance features of the objects. The visual relationship characterizes the semantic association and relative position among the objects. Secondly, a Visual Relationship Improving module is presented to weigh the importance of appearance feature and geometry feature of query object to the modeled visual relationship. Then, the visual relationship among different objects is adaptively improved according to the constructed importance, especially the objects with weak dependence on appearance features, thereby enhancing their semantic association. Extensive experiments on MS COCO dataset demonstrate that the proposed method outperforms the state-of-the-art methods.

A new approach enabling a mobile robot to recognize and classify furniture-like objects composed of assembled parts using a Microsoft Kinect is presented. Starting from considerations about the structure of furniture-like objects, i.e., objects which can play a role in the course of a mobile robot mission, the 3D point cloud returned by the Kinect is first segmented into a set of “almost convex” clusters. Objects are then represented by means of a graph expressing mutual relationships between such clusters. Off-line, snapshots of the same object taken from different positions are processed and merged, in order to produce multiple-view models that are used to populate a database. On-line, as soon as a new object is observed, a run-time window of subsequent snapshots is used to search for a correspondence in the database.Experiments validating the approach with a set of objects (i.e., chairs, tables, but also other robots) are reported and discussed in detail.  相似文献
