One of the key features of virtually all object recognition systems is the ability do deal with occlusions of detected objects. This article is focused on identification of occluded artificial objects such as square markers. The article reviews frequently used methods for detection of partially occluded markers. Further, our implementation of two object recognition methods is presented. The fir...

Most object recognition systems use information from a single image of an object In many cases a single view may not contain su cient features to recognize the object unambiguously Hence more than one view is necessary With an active sensor the recognition process therefore involves identi cation of a view of an object and if nec essary planning the next view This paper presents a new on line r...

With the increasing storage capacity of computers, it became evident that the use of a hierarchical le system no longer ts the interests of the user, i.e., with this kind of le system the user cannot nd a le in an easy, quick and intuitive way. For this reason, the concept of Semantic File System became quite popular. This is a system for storing and organizing information, that allows associat...

This work is part of project C EPRU , it describes the design phase of a system to classify everyday life sounds, based on separation and classification of audio sources in a habitat. Based on previous work, where we collected database and analyzed some sounds, an application of telemonitoring of the elderly or disabled is proposed. First the key concepts of the research area are presented, we ...

Previous work on visual short-term memory (VSTM) capacity has typically used patches of color or simple features which are drawn from a uniform distribution, and estimated the capacity of VSTM to be 3-4 items (Luck & Vogel, 1997). Here, we introduce covariance information between colors, and ask if VSTM can take advantage of this redundancy to form a more efficient representation of the display...

This paper is mainly based on video composition for reducing the size of a video by extracting the unwanted information with suitable algorithm. It will widely focus on easy uploading the data in a common network. This is very helpful to reduce the time of a data transferring to the server. Hence the user can easily access the data in a public network with less time period. Video can be process...

This paper presents an augmented reality application framework which does not require specialized hardware or pre-calibration. Features extracted using SURF are matched between consecutive frames in order to determine the motion of the detected known object with respect to the camera. Next, a bi-directional optical flow algorithm is used to maintain the performance of the system to realtime. Th...

digital preservation refers to an important aspect that most iranian digital library initiatives lack. this component is security. while a digital library may be misconceived as an information supply space without a physical form, the same security concerns in force for operation of physical library are valid. unlike the analog materials, all digital copies of digital materials are original. a ...

Introduction: Nowadays applying computer in image processing is being improved revolutionary for solving medical images deficiencies. Image features that are analysis in image processing show image information. The aim of the present study was to find correlation between CT- scan and MRI images' features. Materials and Methods: After data acquisition, applying...

The purpose of this study was to examine the effects of two interventions, motivational signs and artwork, on stair use in a campus building. Methods: A longitudinal intervention study with no control group was designed to evaluate the effects of motivational signs and art murals on stair use in a six-story building. Sensors were installed in stairwells to monitor stair use. After a three week ...
