Abstract: A method of tracking an object across a sequence of video frames using a natural language query includes receiving the natural language query and identifying an initial target in an initial frame of the sequence of video frames based on the natural language query. The method also includes adjusting the natural language query, for a subsequent frame, based on content of the subsequent frame and/or a likelihood of a semantic property of the initial target appearing in the subsequent frame. The method further includes identifying a text driven target and a visual driven target in the subsequent frame. The method still further includes combining the visual driven target with the text driven target to obtain a final target in the subsequent frame.

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.

Abstract: The invention relates to a method for reducing the PAPR in FRFT-OFDM systems, which belongs to the field of broadband wireless digital communications technology. The method is based on fractional random phase sequence and fractional circular convolution theorem, which can effectively reduce the PAPR of the system. The method of the invention has the advantages of simple system implementation and low computational complexity. In this method, the PAPR of the system can be effectively reduced while maintaining the reliability of the system. When the number of candidate signals is the same, the PAPR performance of the present method was found to be almost the same as that of SLM and better than that of PTS. More importantly, the present method has lower computational complexity than that of SLM and PTS methods.

Abstract: A physical parameter estimating method, a physical parameter estimating device, and electronic apparatus are disclosed. The method includes: reading a Newton's rings fringe pattern of a unit to be measured; calculating a magnitude spectrum of an intensity distribution signal of at least one first-direction pixel set in the Newton's rings fringe pattern under each fractional Fourier transform (FRFT) order in a searching range of FRFT orders; determining a matched order of the intensity distribution signal according to the calculated magnitude spectrums; and estimating a physical parameter involved in the interferometric measurement according to at least the matched order. Therefore, physical parameters of the unit to be measured can be estimated with high accuracy even in presence of noise and obstacles in the fringe pattern.

Abstract: A method of tracking a position of a target object in a video sequence includes identifying the target object in a reference frame. A generic mapping is applied to the target object being tracked. The generic mapping is generated by learning possible appearance variations of a generic object. The method also includes tracking the position of the target object in subsequent frames of the video sequence by determining whether an output of the generic mapping of the target object matches an output of the generic mapping of a candidate object.
