Abstract

Disclosed are a method and apparatus for summarization of unsupervised video with efficient key frame selection reward functions. Frame-level visual features are extracted from an input video. An attention weight is computed and an importance score is represented as a frame tracking probability for selecting a key frame using the attention weight. A temporal consistency reward function and a representativeness reward function are obtained so as to select the key frame, based on a visual similarity distance and temporal distance between key frames, and an attention-based video summarization network is trained to predict an importance score for selecting a key frame of a video summary by using the temporal consistency reward function and the representativeness reward function. A video summary is created by selecting a corresponding key frame based on the predicted importance score, the quality of the created video summary is evaluated, and policy gradient learning is performed for the attention-based video summarization network. Regularization and reconstruction loss is calculated for controlling the probability to select a key frame by using the importance score of the selected key frame. A video summary is created based on the calculated regularization and reconstruction loss.

Abstract

The present embodiment provides a composite film in which a plurality of composite inorganic particles, which are inorganic particles having a fluoropolymer coating film formed therein, are sintered to form a plane shape. Therefore, the low dielectric inorganic particle composite film may reduce signal loss by being hybridized with an interlayer insulator in a high-frequency 5G area. The low dielectric inorganic particles may minimize transmission loss by enhancing dielectric properties when applied to a 5G smartphone substrate and an IF cable, since the composite film used as an interlayer insulator for a communication substrate material comprises only the inorganic particles. In addition, application of the low dielectric inorganic particles may be expanded to vehicles, construction, and IoT products which will use 5G communication in the future.

Abstract

Disclosed are a method and device for managing a BWP in a non-terrestrial network. A method of a terminal comprises the steps of: receiving BWP switching setting information from a satellite; confirming a BWP switching combination indicated by the BWP switching setting information; performing a BWP switching operation according to a switching order determined by the BWP switching combination; and communicating with the satellite via the BWP switched according to the BWP switching operation.

Abstract

The electronic apparatus includes a memory stored with a multiple light field unit (LFU) structure in which a plurality of light fields is arranged in a lattice structure, and a processor configured to, based on a view position within the lattice structure being determined, generate a 360-degree image based on the view position by using the multiple LFU structure, and the processor is configured to select an LFU to which the view position belongs from among the multiple LFU structure, allocate a rendering field-of-view (FOV) in predetermined degrees based on the view position, generate a plurality of view images based on a plurality of light fields comprising the selected LFU and the allocated FOV, and generate the 360-degree image by incorporating the generated plurality of view images.
