2021 arXiv   pre-print
Our system produces new video sequences by minimizing a perceptual distance of images from an existing animation video clip.  ...  In contrast to previous work on animation video resequencing, the proposed framework applies to wide range of image styles and does not require hand-crafted feature extraction, background subtraction,  ...  We also believe our framework could assist users in creating a comprehensive animation dataset by extracting many smooth subsequences from existing animation data.  ...

(a) Method of Making Reusable. To make existing sequences reusable, it is necessary to extract the motion at the same time as the extraction of the model shape from the animation.  ...  The main approach for the reuse of motion data is the reuse of the actual motion data itself.

Limbs detection and tracking of head-fixed mice for behavioral phenotyping using motion tubes and deep learning

Waseem Abbas, David Masip, Andrea Giovannucci
2020 IEEE Access  
Here, we propose a deep learning-based image segmentation framework to automatically extract and label limb movements from movies capturing frontal and lateral views of head-fixed mice.  ...  Given that most of this raw data is unlabeled, great effort is required to adapt it for behavioral phenotyping or signal extraction, for behavioral and neurophysiological data, respectively.  ...  A single motion sequence is formed by stacking feature vectors extracted from D lstm motion tubes by the CNNs in correct chronological sequence.  ...

Human Animation from 2D Correspondence Based on Motion Trend Prediction [chapter]

Li Zhang, Ling Li
2006 Lecture Notes in Computer Science  
Motion trend prediction is suggested to to recover smooth human motions with high efficiency; while its outputs are guaranteed to not only resemble the original motion from the same viewpoint the sequence  ...  Experiment carried on real video data will be discussed as well, which indicate that the proposed method is able to recover smooth human motions from their 2D image features with high accuracy.  ...  To ensure accurate image feature extraction from real video sequence and to reduce unnecessary noises, color labels are stuck to the human object at joint positions.  ...

2003 2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698)  
In this paper, the concept of speech-assisted facial expression analysis and synthesis is proposed, which shows that the speech-driven facial animation technique not only can be used for expression synthesis  ...  From the input speech, the mouth shape can be estimated from the audio-visual model. Thus, the large search space of mouth appearance can be reduced for mouth tracking.  ...  Synthesized images from different view angles are also depicted. When compared to the original image, the synthesized image is a little blurred due to dimensional reduction by PCA.  ...
