Analyzing Effects of Time on Human Accuracy to differentiate CGI vs Photographic Portraits
The last decade has seen the most remarkable growth in the field of computer-generated imagery. These advances made it easier to create CGI(Computer Generated Imagery) images that highly resemble photographic images. However, despite these advances, the human observer’s ability to differentiate the CGI and Photographic images is good. However, we propose that time can affect the accuracy of humans. In this paper, we describe an experiment to validate this claim and analyze the effects of time on human accuracy to differentiate CGI and photographic images. We find that with more time provided to analyze the image, the accuracy of the human participant to differentiate the CGI and photographic image increases.
