    Abstract: An apparatus may be configured to obtain, for a Siamese neural network having a recurrent neural network (RNN), an initial representation associated with a target object at a first time step and a set of candidate regions at a current time step. The apparatus may determine an updated representation associated with the target object based on the initial representation at the first time step and observed information associated with the target object at a set of previous time steps, and the observed information associated with the target object may be represented by a hidden state of the RNN. The apparatus may output the updated representation associated with the target object for matching with the set of candidate regions at the current time step by the Siamese neural network. The apparatus may determine the updated representation further based on a hidden state at a previous time step.

    Abstract: In one configuration, a visual object tracking apparatus is provided that receives a position of an object in a first frame of a video, and determines a current position of the object in subsequent frames of the video using a Siamese neural network To facilitate determining the current position of the object, the apparatus may adjust a spatial resolution of an image, adjust a size of a probe region, and/or adjust a scale of a plurality of sampled images. In one configuration, a visual object tracking using a Siamese neural network is provided. The apparatus feeds outputs from a plurality of subnetworks of the Siamese neural network to a comparison layer. In addition, the apparatus compares, at the comparison layer, inputs from the plurality of subnetworks to generate a comparison result. Further, the apparatus combines comparison results based on weights to obtain a final comparison result.
