Patent number: 10957053Abstract: A multi-object tracking (MOT) framework uses a dual Long Short-Term Memory (LSTM) network (Siamese) for MOT. The dual LSTM network learns metrics along with an online updating scheme for data association. The dual LSTM network fuses relevant features of trajectories to interpret both temporal and spatial components non-linearly and concurrently outputs a similarity score. An LSTM model can be initialized for each trajectory and the metric updated in an online fashion during the tracking phase. An efficient and feasible visual tracking approach using Optical Flow and affine transformations can generate robust tracklets for initialization. Thus, the MOT framework can achieve increased tracking accuracy. Further, the MOT framework has improved performance and can be flexible utilized in arbitrary scenarios.Type: GrantFiled: October 18, 2018Date of Patent: March 23, 2021Assignee: DEEPNORTH INC.Inventors: Jinjun Wang, Xingyu Wan

Publication number: 20200125897Abstract: A semi-supervised model incorporates deep feature learning and pseudo label estimation into a unified framework. The deep feature learning can include multiple convolutional neural networks (CNNs). The CNNs can be trained on available training datasets, tuned using a small amount of labeled training samples, and stored as the original models. Features are then extracted for unlabeled training samples by utilizing the original models. Multi-view clustering is used to cluster features to generate pseudo labels. Then the original models are tuned by using an updated training set that includes labeled training samples and unlabeled training samples with pseudo labels. Iterations of multi-view clustering and tuning using an updated training set can continue until the updated training set is stable.Type: ApplicationFiled: October 18, 2018Publication date: April 23, 2020Inventors: Jinjun Wang, Xiaomeng Xin

Publication number: 20200125925Abstract: A foreground attentive neural network is used to learn feature representations. Discriminative features are extracted from the foreground of the input images. The discriminative features are used for various visual recognition tasks such as person re-identification and multi-target tracking. A deep neural network can include a foreground attentive subnetwork, a body part subnetwork and the feature fusion subnetwork. The foreground attentive subnetwork focuses on foreground by passing each input image through an encoder and decoder network. Then, the encoded feature maps are averagely sliced and discriminately learned in the following body part subnetwork. Afterwards, the resulting feature maps are fused in the feature fusion subnetwork. The final feature vectors are then normalized on the unit sphere space and learned by following the symmetric triplet loss layer.Type: ApplicationFiled: October 18, 2018Publication date: April 23, 2020Inventors: Jinjun Wang, Sanpin Zhou
