Abstract: A system and method for selecting portions of video data from preview video data is provided. The system may extract image features from the preview video data and discard video frames associated with poor image quality based on the image features. The system may determine similarity scores between individual video frames and corresponding transition costs and may identify transition points in the preview video data based on the similarity scores and/or transition costs. The system may select portions of the video data for further processing based on the transition points and the image features. By selecting portions of the video data, the system may reduce a bandwidth consumption, processing burden and/or latency associated with uploading the video data or performing further processing.

Abstract: A system and method for generating preview data from video data and using the preview data to select portions of the video data or determine an order with which to upload the video data. The system may sample video data to generate sampled video data and may identify portions of the sampled video data having complexity metrics exceeding a threshold. The system may upload a first portion of the video data corresponding to the identified portions while omitting a second portion of the video data. The system may determine an order with which to upload portions of the video data based on a complexity of the video data. Therefore, portions of the video data that may require additional processing after being uploaded may be prioritized and uploaded first. As a result, a latency between the video data being uploaded and a video summarization being received is reduced.

Abstract translation: 一种用于从视频数据生成预览数据并使用预览数据来选择视频数据的部分或者确定用于上传视频数据的顺序的系统和方法。 系统可以采样视频数据以产生采样的视频数据，并且可以识别具有超过阈值的复杂度度量的采样视频数据的部分。 该系统可以在省略视频数据的第二部分的同时上传与所识别的部分相对应的视频数据的第一部分。 系统可以基于视频数据的复杂度来确定用于上传视频数据的部分的顺序。 因此，上传后可能需要额外处理的视频数据的部分可以被优先排列并首先上传。 因此，正在上传的视频数据和正在接收的视频摘要之间的延迟被减少。
