Network architecture for the player identification model. The networks accepts a player tracklet as input. Each tracklet image is passed through a ResNet18 to obtain time ordered features F . The features F are input into three 1D convolutional blocks, each consisting of a 1D convolutional layer, batch normalization, and ReLU activation. In this figure, k and s are the kernel size and stride of convolution operation. The activations obtained from the convolutions blocks are mean-pooled and passed through a fully connected layer and a softmax layer to output the probability distribution of jersey number p jn .

Tracking and identifying players is a fundamental step in computer vision-based ice hockey analytics. The data generated by tracking is used in many other downstream tasks, such as game event detection and game strategy analysis. Player tracking and identification is a challenging problem since the motion of players in hockey is fast-paced and non-...

... to the bounding box o i is input into a backbone 2D CNN, which outputs a set of time-ordered features {F = {f 1 , f 2 .....f n }f i ∈ R 512 }. The features F are input into a 1D temporal convolutional network that outputs probability p ∈ R 86 of the tracklet belonging to a particular jersey number class. The architecture of the 1D CNN is shown in Fig. ...

The existence of anisotropy phenomena in the subsurface will affect the image quality of seismic data. Hence a prior knowledge of the type of anisotropy is quite essential, especially when dealing with deep water targets. The preliminary result of the anisotropy of the well-based modelling in deep water exploration and development is discussed in t...

The aim of this study was to describe the game activity profile of a professional ice hockey team with special emphasis on fatigue development and playing position. Data were collected using a wearable 200-Hz accelerometric system and heart rate (HR) throughout eight official games in a professional ice hockey team (6 defensemen and 11 forwards; n...

Flexoelectricity may have an important impact on the switching properties of nematic and cholesteric liquid crystals due to the linear coupling between the flexoelectric polarization of the liquid crystal and the applied electric field. This coupling is the origin of the extraordinary electro-optic effect in cholesterics aligned in the uniform lyin...
