چکیده
In the past, the fields of computer vision and computer graphics have been considered as tackling the inverse problems. Traditionally, computer vision starts with input images and process them for the purpose of understanding geometric and physical properties of objects and scenes, and to build appropriate models. On the other hand, traditional computer graphics starts with geometric models and then generates, manipulates, and displays virtual representations in the form of images. In the recent years, we have seen great efforts towards the integration of computer vision and computer graphics techniques, in particular, in the areas of realistic modeling of objects and scenes, interactive computer graphics, and augmented reality. Which are the main reasons that have brought the researchers of computer vision and computer graphics closer together? Computer graphics community has been active in inventing increasingly better, faster, and more complex methods of animation for creating virtual 3D synthetic environments. This paradigm has been successfully demonstrated in the constantly expanding series of complex digital animations. Yet, even though these animations have been successful (also commercially), it is clear that in order to create even more realistic virtual environments and on a much larger scale, the cost and time involvement have to be lowered. Such a leap in cost and quality is possible by incorporating sensor data of actual physical objects and environments, that can later be modified and extended with synthetic data. For example, it should be less costly to make a 3D model of a complex geometric object directly from images, than to have an animator construct such a model by hand. Sensor data, which are crucial for an efficient creation of larger and more realistic virtual(ized) environments, need to be properly interpreted, processed, and modeled—and this is precisely what computer vision does. In other words, computer vision provides the tools needed

At the beginning of his magnum opus al-Hekmat al-Muta’aleiat fi al-Asfar al-Aqliiat, Mulla Sadra says that he has nominated and arranged his book according to “the four journeys” of the Mystics. What he and the Mystics say on these journeys reminds those familiar with Greek philosophy of Plato’s Phaedrus and Republic (Journey of souls onto sky and the Allegory of Cave, respectively).

متن کاملA Glance at Psychophysics Software Programs
Visual stimulation with precise control of stimulus has transformed the field of psychophysics since the introduction of personal computers. Luminance and chromatic features of stimulus, timing, and position of the stimulus are the main features that could be defined using programs written specifically for psychophysical experiments. In this manuscript, software used for the psychophysical expe...
