| Outline of Final Research Achievements |
In this study, we proposed an image generation method for textures with desired visual sensory texture. First, (1) subjective evaluation experiments were conducted on texture images to quantify the sensory texture. Next, (2) style features were extracted using a pre-trained VGG19. Then, (3) a sensitivity evaluation model was constructed by formulating the relationship between the quantified sensory quality and the extracted style features. Finally, (4) based on the obtained model, style features were calculated when the desired emotional quality was exaggerated, and images were generated by optimization. Furthermore, the effectiveness of the method was demonstrated through validation experiments, which confirmed that the emotional quality of the generated images was significantly improved compared to the original images.
