Domain Generalized Fashion Object Detection using Style Augmentation and Attention
http://doi.org/10.5626/JOK.2023.50.10.845
With the combination of fashion and computer vision, fashion object detection using deep learning has gained much interest. However, due to the nature of supervision, the performance of the model drops when images with different characteristics are used. We define the dataset with different characteristics and the characteristic of the domain as ‘domain’ and ‘style’, respectively, and propose a new augmentation method that mixes up the existing domain’s style to make a new style. We also use an attention method to extract important features from the images. Using a stylized fashion detection dataset, style deepfashion2, we show that the proposed method enhances performance within all domains.

Virtual try-on (VITON) technology is receiving a lot of attention with the development of Generative Adversarial Networks (GANs) [1]. Previous approaches to VITON synthesized 2D model images and in-shop clothing images using a generative model. However, when synthesizing the top, VITON erroneously changes pixels in unintended areas, such as the background and pants. In this study, we propose the VITON Artifact Correction System (VACS), which divides and protects targeted clothes synthesized in VITON by fashion object segmentation, and replaces the pixels corresponding to the remaining areas with the original model image to increase the realism of the final composition.

Most previous named-entity(NE) recognition studies have been based on supervised learning methods. Although supervised learning-based NE recognition has performed well, it requires a lot of time and cost to construct a large labeled corpus. In this paper, we propose an NE recognition training method that uses an automatically generated labeled corpus to solve this problem. Since the proposed method uses a large machine-labeled corpus, it can greatly reduce the time and cost needed to generate a labeled corpus manually. In addition, a bagging-based bootstrapping technique is applied to our method in order to correct errors from the machine-labeled data. As a result, experimental results show that the proposed method achieves the highest F1 score of 70.76% by adding the bagging-based bootstrapping technique, which is 5.17%p higher than that of the baseline system.
