in this paper, a new method for determining position and orientation of a coordinate system using its image is presented. this coordinate system is a three dimensional non-orthogonal system in respect to the two dimensional and orthogonal camera coordinate system.  in real world, it’s exactly easy to select three directions on an object so that they don’t be orthogonal and on a plane. the image...

target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...

abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...

Synthetic Aperture Radar (SAR) is widely used in different weather conditions for various applications such as mapping, remote sensing, urban, civil and military monitoring. Recently, a new radar sensor called Video SAR (ViSAR) has been developed to capture sequential frames from moving objects for environmental monitoring applications. Same as SAR images, the major problem of ViSAR is the pres...

The cinematic frame is the boundary between the cinematic image and the outside world. In the history of theoretical studies of cinema, the essence of the cinematic frame is analyzed in many ways. Here we focus on two significant viewpoints among them. One of these significant viewpoints considered cinematic frame as a window, and another one considered it as a framework. Both of them had (and ...

This paper presents a method for determining the six-degreeof-freedom (DOF) transformation between a camera and a base frame of interest, while concurrently estimating the 3D base-frame coordinates of unknown point features in the scene. The camera observes the reflections of fiducial points, whose base-frame coordinates are known, and reconstruction points, whose base-frame coordinates are unk...

the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...

this study was an attempt to investigate and compare the effect of lexical inferencing and concept mapping on developing vocabulary retention of iranian language learners. sixty homogeneous students from different intact classes who were being taught as intermediate learners in sokhan english institute participated in this study. they were in different classes. a teacher made test as a pre-test...

In most human made scenes, such as high-rise urban city or indoor environment, the surface normal vectors direction are concentrated in three orthogonal principal directions. The scene of a pattern is called Manhattan World (MW), and coordinate frame formed by directions Frame (MF). MF estimation methods have been applied to many different fields, reconstruction, Visual based Simultaneous Local...

ku and kv are the focal lenght expressed in pixel unit. They are close related to real f focal lenght and τ aspect ratio but this syntax is slightly more compact. K converts from camera coordinates to image coordinates (expressed in homogeneous form). The R is the rotation matrix. Since in R a unique reference frame not exists to model rotation from 3 angles we are not to deal with the inner fo...
