研究目的
Investigating the connection among optical aspects of photographic composition and the quality, perception and interpretation of the level of realism of images.
研究成果
The results suggest a close relationship between the quality of image representation via optical contrasts and user-perceived realism. Images with strong compliance to photographic principles were well-evaluated for realism, while those with absence were poorly evaluated. This supports the importance of photographic theory in image design for virtual reality applications, though further studies are needed to confirm and expand on these findings.
研究不足
The study has limitations such as the sample size and selection method (Facebook friends may not be representative), potential biases in image selection, and the need to isolate other variables (e.g., presence of human figures) in future research. Observations 2 and 3 lacked statistical significance, indicating areas for optimization.
1：Experimental Design and Method Selection:
The experiment was conducted in two steps. The first step involved technical analysis of optical aspects (lighting, field depth, movement) using the Campos method based on contrast theory, with a 7-point Likert scale for quality assessment. The second step involved a user questionnaire to collect subjective data on perceived realism using a similar Likert scale.
2：Sample Selection and Data Sources:
19 images were randomly selected from a bank of 400 images (virtual and real scenes). User data came from 299 respondents selected randomly from 4,000 Facebook friends.
3：List of Experimental Equipment and Materials:
Not specified in the paper.
4：Experimental Procedures and Operational Workflow:
First step: Specialist analyzed images for optical quality. Second step: Users rated realism via an online questionnaire.
5：Data Analysis Methods:
Objective and subjective data were compared to check for convergence or divergence, using statistical tests for significance.
