In a two-sided market, the two-sided platform may choose to invest in service effort to attract buyers and sellers, meanwhile buyers and sellers are price-sensitive. This paper investigates how the two-sided platform sets her pricing and service effort strategies when the buyers and sellers are price-sensitive. The equilibrium strategies are derived when the platform does not offer service effort and when the platform offers service effort. The results indicate that, the cross-network externality does not impact on the price when the platform does not offer service effort, but it impacts on the price positively when the platform offers service effort. Meanwhile, the price-sensitivity impacts on the platform’s profit and optimal scales of buyers and sellers negatively. Then, the results show that the optimal strategy for the platform is offering service effort, but it may hurt the buyers and sellers’ surplus and social welfare in certain scenario.

This paper introduces a new dataset for the realistic synthesis of letters on food. Specifically, the "Ketchup GAN" dataset consists of real-world images of egg omelettes decorated with ketchup letters. Our dataset contains sufficient size and variety to train and evaluate deep learning-based generative models. In addition, we generate a synthetic ketchup-free set, which enables us to train paired-based generative adversarial networks (GAN). The ketchup GAN dataset comprises more than two thousand images of omelette dishes collected from Twitter. Automatically generated segmentation masks of egg and ketchup are also provided as part of the dataset. Thus, we can evaluate generative models based on segmentation inputs as well. With our dataset, two state-of-the-art GAN models (Pix2Pix and SPADE) are reviewed on photorealistic ketchup letter synthesis. We finally present an automatic application of omelette decoration with ketchup text input from users. The dataset and more details are publicly available at https://mm.cs.uec.ac.jp/omrice/.

In this study, we focused on the fact that the color information of an image has a significant effect on the emotion recalled, and we created a dataset with discrete and continuous emotion labels for color and grayscale image pairs, which are not present in existing emotion image datasets. As a result of the analysis of the continuous-valued emotion labels, we found that the color images evoked a wider range of positive and negative emotions. We also conducted experiments to transform the color of the image to the target emotion using the emotion label and the image as input and succeeded in changing the color of the entire image according to the input emotion value. Another experiment is conducted to convert the emotion category and we confirmed that the image was generated in such a way that the evoked emotion was changed compared to the original image.

This paper proposes a method to estimate a group of featured characters during an arbitrary period in comics. Comics have so many aspects of attractiveness such as illustrations and quotes. The storyline, which is one of the attractive of comics, enables us to enjoy the dramas in comics. In comics, the story is driven by characters' activities represented in multimedia forms: emotion, speech, and some other actions. This paper, as a first step to recognize the storyline, tackles the estimation of a group of featured characters in a given period. To compute the storyline of comics with the facility, the proposed method uses a sequence of characters' appearances for each page. The experiment showed that the proposed method outperformed the comparative methods in estimating groups of featured characters with a 0.82 F-value on average while comparative methods showed 0.67 and 0.48. The results showed that sequences of characters' appearance, which are relatively easy to obtain, were sufficient to catch the brief storyline i.e. featured characters in a story.
