Interior image recommendations have been paid attention to with the development of image retrieval technology. Although a classification model is often used to model user-preferred interiors, it is not suitable for explaining why users prefer them. On the other hand, LDA, which analyzes sentence features based on latent features, can better understand sentences by estimating latent features in sentences. Therefore, we propose a latent feature estimation method in interior images by incorporating spatial features of images and LDA to understand the structure of preferred interior images by users. Specifically, instead of sentences, we use interior images to extract spatial features using BoVW based on SURF features and estimate topics based on the histograms by LDA. We compared the proposed method with subject experiments in interior images with several styles. We verified that the proposed method could estimate similar topics compared to the subject’s subjective view.
