반려견의 행동인식기술은 다양한 센서들에서 입력되는 반려견의 동작과 관련된 정보를 분석하고 해석하여 반려견이 어떤 행동을 취하고 있는지를 인식하는 기술이다. 음성인식기술은 컴퓨터가 청각 자료를 수집, 분석하여 훈련된 데이터와 비교를 통해 소리를 분류하는 기술이다. 본 논문에서는 딥러닝을 기반으로 행동인식기술과 음성인식기술을 적용하여 반려견의 감정을 판단하는 기법을 제안한다. 이러한 기법은 반려견의 감정을 쉽게 파악하여 반려견 보호자가 반려견의 행동과 감정에 대한 이해를 쉽고 빠르게 할 수 있으므로, 보호자에게 즐거운 반려 생활이 가능하도록 도움을 줄 수 있다.

In this study, we propose a method for real-time recognition and analysis of dog behavior using a motion sensor and deep learning techonology. The existing home CCTV (Closed-Circuit Television) that recognizes dog behavior has privacy and security issues, so there is a need for new technologies to overcome them. In this paper, we propose a system that can analyze and care for a dog's behavior based on the data measured by the motion sensor. The study compares the MLP (Multi-Layer Perceptron) and CNN (Convolutional Neural Network) models to find the optimal model for dog behavior analysis, and the final model, which has an accuracy of about 82.19%, is selected. The model is lightened to confirm its potential for use in embedded environments.

본 논문은 기존의 웨어러블 센서 방식이 아닌 영상으로 반려견의 행동을 분석하는 연구에 대한 것이다. 제안한 시스템은 영상에서 반려견의 영역을 탐지하고, 탐지된 이미지에서 반려견의 관절 좌표를 추출하여 행동을 판단하는 방식이다. 모든 프레임에 대해 처리하지 않고, 일정 주기 단위로 영상을 처리해 실시간성을 확보하였다. 제안한 시스템의 유용성은 실험으로 검증하였으며, 유의미한 실험 결과를 얻을 수 있었다.

This paper implements a method of extracting an object about a dog through real-time image analysis and classifying dog behaviors from the extracted images. The Darknet YOLO was used to detect dog objects, and the Teachable Machine provided by Google was used to classify behavior patterns from the extracted images. The trained Teachable Machine is saved in Google Drive and can be used by ml5.js implemented on a node.js server. By implementing an interactive web server using a socket.io module on the node.js server, the classified results are transmitted to the user's smart phone or PC in real time so that it can be checked anytime, anywhere.

In recent years, there has been a growing interest in deep learning-based animal pose estimation, especially in the areas of animal behavior analysis and healthcare. However, existing animal pose estimation techniques do not perform well when body parts are occluded or not present. In particular, the occlusion of dog tail or ear might lead to a significant degradation of performance in pet behavior and emotion recognition. In this paper, to solve this intractable problem, we propose a simple yet novel framework for pet pose estimation where pet pose is predicted on an outpainted image where some body parts hidden outside the input image are reconstructed by the image inpainting network preceding the pose estimation network, and we performed a preliminary study to test the feasibility of the proposed approach. We assessed CE-GAN and BAT-Fill for image outpainting, and evaluated SimpleBaseline for pet pose estimation. Our experimental results show that pet pose estimation on outpainted images generated using BAT-Fill outperforms the existing methods of pose estimation on outpainting-less input image.

This study analyzed the Internet consumption behavior concerning pet care through in-depth interviews with 11 people who take care of pets. In this study, along with owners of domestic companion animals, stray cat caregivers were included as pet consumers, which have not yet been included in this category in existing research. Internet consumption was found to differ between people with dogs and people with cats. In the case of dog owners, they bought a lot of bath products, clothes harnesses, and strollers that were not appropriate for cats. Although the pet-poor phenomenon is known to occur a lot among young consumers, who care for pets behavior at the cost of money spent on themselves, even stray cat caregivers, mostly middle-aged women, are wary of becoming pet-poor. It cannot be said that there are gender differences in online shopping of pet consumers. In general, women, who did mainly Internet shopping, and if they are not used to using the Internet, their husbands made purchases online instead.
