| 内容記述 | A logo is a symbolic presentation that is designed not only to identify a product manufacturer but also to attract the attention of potential buyers. Manufacturers carefully design their logos so that their characteristics, impressions and philosophies are expressed. Moreover, logos on a person’s belongings can play an important role in characterizing and identifying the person. Extraction and recognition of logos from images captured by multiple surveillance cameras could provide useful information for identification and tracking of individuals. Automatic extraction and recognition of shoe logos using image analysis techniques is challenging because they have characteristics that distinguish them from those of other products, and their appearance can vary substantially. Automatic extraction and recognition techniques must handle these problems properly, because shoes are usually worn on feet and,therefore, move frequently with respect to stationary cameras. Additionally, since shoe logos are usually appeared as an integrated design component of shoe design, they have significant within-class appearance variation due to the variation in color, fabric material, shape of shoe and dirt or aging of shoe. The extraction and recognition of logos in images has attracted the attention of many researchers. Several studies on the automatic extraction of logos have been reported. Affine and non-rigid transformation occurs frequently in real-world images. This makes logo detection and recognition complex, especially for model-based approaches, owing to the difficulty in collecting sufficient samples to obtain a robust model. Several related works [8, 9, 14, 15] address this problem. While these related works were carefully designed for handling appearance variations, they did not pay enough attention for large within-class appearance variation. Therefore, extending the target of these methods for shoe logos is quite difficult. Moreover,deep neural network architectures have been employed in image recognition tasks due to their promising performance and high adaptivity. However a deep learning method requires a large-scale, accurately annotated dataset for training. Creating such a dataset for deep learning is difficult because shoe logos have a wide variety of appearances even in the same bland. In the present paper, we propose an automatic extraction and recognition method for shoe logos using a limited number of training samples. The proposed method employs maximally stable extremal regions (MSERs) [4] for the initial region extraction, an iterative algorithm for region grouping and gradient features, and two-stage support vector machines (SVM) for logo recognition. For performance evaluation, we use the IEICE-PRMU shoe logo dataset which consists of shoe logo images captured in uncontrolled condition. The results of performance evaluation experiments show that the proposed method achieves promising performance for both logo extraction and recognition. In the present paper, Chapter 1 gives the introduction of this research. Chapter 2 expresses related works. Chapter 3 shows the proposed method in detail. Chapter 4 represents evaluation experiments. In the last Chapter, a conclusion is explained. Appendix A submits the method which proposed methods are employed. Appendix B describes individual diversification extraction strategies. Postscripts shows where the program is located and presentation side which is used on master research presentation. | |||||||||
