故事可视化中合成图像构图结构选择的研究-计算机科学与技术专业论文.docxVIP

ABSTRACT With the development of technology，various of techniques are shown in front of people more and more intuitively, changing the way we live and communicate quietly. Take storytelling as an example, we change the way of telling story from language, words to pictures. We can improve the efficiency of communication by using pictures gotten from story visualization as an auxiliary way. By referencing others work in this field, we can select sub graph having more better composition structure using image segmentation and image synthesis. The main contribution of this work can be summarized follows: Firstly, we use an image retrieval method based on semantic information to search pictures in the system. After searching, we use image segmentation and image synthesis to get the picture that fits our needs better. Then, we can select sub graph having much better composition structure. In this process, although the new pictures can express the correct meaning of user, they are not able to give people the feeling of visual beauty. We use the one-third principle and diagonal line principle, which meet the principle of peoples aesthetic view, to select sub graph of the synthetic image. Finally, we try to add grammatical constraint to ensure that the synthetic image meets the user’s need through the process of image synthesis. We know the relative position relationship of the objects in the image according to grammatical constraint, which ensure that the synthesis result matches the input sentence. Therefore, the final result will be logical, rather than a meaningless images.
