We describe a system for identifying dog emotions based on dogs' facial expressions and body posture. Towards that goal, we built dataset with 2184 images of ten popular breeds, grouped into seven similarly sized primal mammalian emotion categories defined by neuroscientist psychobiologist Jaak Panksepp as 'Exploring', 'Sadness', 'Playing', 'Rage', 'Fear', 'Affectionate' 'Lust'. modified the contrastive learning framework MoCo (Momentum Contrast Unsupervised Visual Representation Learning) to train it our original achieved an accuracy 43.2% baseline 14%. also trained this model second publicly available resulted in 48.46% but had 25%. compared unsupervised approach supervised ResNet50 architecture. This model, when tested labels, 74.32.

Dog owners are typically capable of recognizing behavioral cues that reveal subjective states their dogs, such as pain. But automatic recognition the pain state is very challenging. This paper proposes a novel video-based, two-stream deep neural network approach for this problem. We extract and preprocess body keypoints, compute features from both keypoints RGB representation over video. propose an to deal with self-occlusions missing keypoints. also present unique video-based dog behavior dataset, collected by veterinary professionals, annotated presence pain, report good classification results proposed approach. study one first works on machine learning based estimation state.

Veterinary medicine is a broad and developing profession that covers topics such as companion animal health, zoonotic infections, agriculture, community health. The potential for better healthcare diagnostics has sparked growing interest in the application of computer vision (CV) veterinary science discipline recent years. This research investigates extent applications CV techniques, with focus on deep learning approaches, medical imaging, thermal video analysis, alignment diagnostics, post-surgery pet monitoring clinical settings. Salient Object Deduction (SOD), R-CNN, Convolutional Attentive Adversarial Network (CAAN) are examined this study to demonstrate important roles plays addressing issues enhancing overall

Affective states are reflected in the facial expressions of all mammals. Facial behaviors linked to pain have attracted most attention so far non-human animals, leading development numerous instruments for evaluating through various animal species. Nevertheless, manual expression analysis is susceptible subjectivity and bias, labor-intensive often necessitates specialized expertise training. This challenge has spurred a growing body research into automated recognition, which been explored multiple species, including cats. In our previous studies, we presented studied artificial intelligence (AI) pipelines recognition cats using 48 landmarks grounded cats' musculature, as well an detector these landmarks. However, used solely static information obtained from hand-picked single images good quality. study takes significant step forward fully detection applications by presenting end-to-end AI pipeline that requires no efforts selection suitable or their landmark annotation. By working with video rather than still images, this new approach also optimises temporal dimension visual capture way not practical preform manually. The reaches over 70% 66% accuracy respectively two different cat datasets, outperforming landmark-based approaches frames under similar conditions, indicating dynamics matter recognition. We further define metrics measuring dimensions deficiencies datasets faces, investigate impact on performance pipeline.
