Generic Object Recognition Based on Rough Segmentation Data Given by a User

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we revisit a generic object recognition problem from a point of view of human-computer interaction. Many of existing algorithms of the generic object recognition consist of following three tasks: target region segmentation, feature extraction and classification. While these three tasks are automatically processed on a computer in the previous approaches, solving the target region segmentation task by a computer is not always necessary in many practical situations in which a recognition system can request a user to input rough segmentation data of a target. Although rough segmentation may not give enough classification performance, the use of many rough segmentation datasets in learning process will avoid this problem. In order to validate this hypothesis, we created “20 wild bird datasets” and evaluated classification accuracy of the datasets. Our experiments revealed that generating multiple training samples from a single image by using multiple rough segmentation datasets brought positive effects on classification accuracies, especially when image features including spacial information such as PHOG and PHOW were used.
