Feature based classification of computer graphics and real images
2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009Photorealistic images can now be created using advanced techniques in computer graphics (CG). Synthesized elements could easily be mistaken for photographic (real) images. Therefore we need to differentiate between CG and real images. In our work, we propose and develop a new framework based on an aggregate of existing features.

Computer Graphics Identification Combining Convolutional and Recurrent Neural Networks
IEEE Signal Processing Letters, 2018In this letter, a deep-learning-based pipeline is proposed to distinguish photographics (PGs) from computer-graphics (CGs) combining convolutional neural network (CNN) and recurrent neural network (RNN).

Researching Visual Images with Computer Graphics [PDF]
Leonardo, 1996 Research in art history is largely dependent on photographic reproductions of original works. While it revolutionized art history, the use of photography tended to lift large works out of context, aggrandize details through cropping and sacrifice a sense of scale by showing works in isolation.

Use of computer graphic images in teaching dermatology
Computerized Medical Imaging and Graphics, 1992A microcomputer-based system for copying, storing, retrieving, and displaying color still images was assembled from commercially available components. The system was tested against 35-mm color photographic transparencies by measuring the performance of 91 medical students in a task of identifying the primary morphology of eight skin lesion images from ...

Image Processing and Computer Graphics
Computer Graphics and Image Processing, 1979For a number of years, image processing and computer graphics have been treated as separate subjects. Conferences and journals exist for one group or the other but rarely for both groups. However, the hardware for computer graphics, and even for alphanumeric displays, more and more frequently use raster-scan processing.

Second order image statistics in computer graphics
Proceedings of the 1st Symposium on Applied perception in graphics and visualization, 2004The class of all natural images is an extremely small fraction of all possible images. Some of the structure of natural images can be modeled statistically, revealing striking regularities. Moreover, the human visual system appears to be optimized to view natural images. Images that do not behave statistically as natural images are harder for the human

TEACHING IMAGE COMPUTATION: FROM COMPUTER GRAPHICS TO COMPUTER VISION
International Journal of Pattern Recognition and Artificial Intelligence, 2001This paper describes a course in image computation that is designed to follow and build up an established course in computer graphics. The course is centered on images: how they are generated, manipulated, matched and symbolically described. It builds on the student's knowledge of coordinate systems and the perspective projection pipeline.

A raster engine for computer graphics and image composition
Proceedings of APCCAS'94 - 1994 Asia Pacific Conference on Circuits and Systems, 2002A raster engine (RE) is designed and implemented to improve the performance of computer graphics and image composition. The RE hardware can release more than 50% CPU loads. Furthermore, if the approximated Phong method which is proposed is applied, 89% CPU operations are reduced by the RE.

Image Synthesis Based on Computer Graphics
2012The computer simulation can conveniently model the real scenes at little expense. In this paper, in order to realize the synthesis of the object and background images, their image data is firstly obtained through computer simulation. In order to view the background and objects at different angles, the coordinate system is reset according to the ...

Reliability of computer graphic images for visual assessment
The Visual Computer, 1991This paper analyzes the use of computer graphics images as an architectural assessment tool. The characteristics of such images as an architectural simulation tool are discussed and their reliability as an assessment tool is evaluated and compared with that of traditional hand-generated perspective drawings.
