Image Impression Estimation by Clustering People with Similar Tastes

This paper proposes a method for estimating impressions from images according to the personal attributes of users so that they can find the desired images based on their tastes. Our previous work, which considered gender and age as personal attributes, showed promising results, but it also showed that users sharing these attributes do not necessarily share similar tastes. Therefore, other attributes should be considered to capture the personal tastes of each user well. However, taking more attributes into account leads to a problem in which insufficient amounts of data are served to classifiers due to the explosion of the number of combinations of attributes. To tackle this problem, we propose an aggregation-based method to condense training data for impression estimation while considering personal attribute information. For evaluation, a dataset of 4,000 carpet images annotated with 24 impression words was prepared. Experimental results showed that the use of combinations of personal attributes improved the accuracy of impression estimation, which indicates the effectiveness of the proposed approach.
