Patent number: 11810597Abstract: Devices, systems and methods are disclosed for improving story assembly and video summarization. For example, video clips may be received and a theme may be determined from the received video clips based on annotation data or other characteristics of the received video data. Individual moments may be extracted from the video clips, based on the selected theme and the annotation data. The moments may be ranked based on a priority metric corresponding to content determined to be desirable for purposes of video summarization. Select moments may be chosen based on the priority metric and a structure may be determined based on the selected theme. Finally, a video summarization may be generated using the selected theme and the structure, the video summarization including the select moments.Type: GrantFiled: October 4, 2021Date of Patent: November 7, 2023Assignee: Amazon Technologies, Inc.Inventors: Matthew Alan Townsend, Rohith Mysore Vijaya Kumar, Yadunandana Nagaraja Rao, Ambrish Tyagi, Eduard Oks, Apoorv Chaudhri

Patent number: 10582149Abstract: 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.Type: GrantFiled: February 17, 2017Date of Patent: March 3, 2020Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Rohith Mysore Vijaya Kumar, Ambrish Tyagi, Yadunandana Nagaraja Rao, Suresh Bholabhai Lakhani, Amit Kumar Agrawal

Patent number: 10554850Abstract: Devices, systems and methods are disclosed for reducing a perceived latency associated with uploading and annotating video data. For example, video data may be divided into video sections that are uploaded individually so that the video sections may be annotated as they are received. This reduces a latency associated with the annotation process, as a portion of the video data is annotated before an entirety of the video data is uploaded. In addition, the annotation data may be used to generate a master clip table and extract individual video clips from the video data.Type: GrantFiled: March 7, 2019Date of Patent: February 4, 2020Assignee: Amazon Technologies, Inc.Inventors: Matthew Alan Townsend, Eduard Oks, Rohith Mysore Vijaya Kumar, Apoorv Chaudhri, Yadunandana Nagaraja Rao, Ambrish Tyagi

Patent number: 10482925Abstract: 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.Type: GrantFiled: October 13, 2017Date of Patent: November 19, 2019Assignee: Amazon Technologies, Inc.Inventors: Ambrish Tyagi, Suresh Bholabhai Lakhani, Rohith Mysore Vijaya Kumar, Yadunandana Nagaraja Rao, Amit Kumar Agrawal

Patent number: 9965865Abstract: Devices and techniques are generally described for segmentation of image data using depth data. In various examples, color image data may be received from a digital camera. In some examples, depth image data may be received from a depth sensor. In various examples, the depth image data may be separated into a plurality of clusters of depth image data, wherein each cluster is associated with a respective range of depth values. In some further examples, a determination may be made that a first cluster of image data corresponds to an object of interest, such as a human subject, in the image data. In various examples, pixels of the first cluster may be encoded with foreground indicator data. In some further examples, segmented image data may be generated. The segmented image data may comprise pixels encoded with the foreground indicator data.Type: GrantFiled: March 29, 2017Date of Patent: May 8, 2018Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Amit Kumar Agrawal, Abhishek Singh, Visesh Uday Kumar Chari, Prakash Ramu, Lelin Zhang, Qiang Liu, Yadunandana Nagaraja Rao, Rohith Mysore Vijaya Kumar, Weijian Wang

Patent number: 7529651Abstract: A method of building a model for a physical plant in the presence of noise can include initializing the model of the physical plant, wherein the model is characterized by a parameter vector, estimating an output of the model, and computing a composite cost comprising a weighted average of an error between the estimated output from the model and an actual output of the physical plant, and a derivative of the error. The method further can include determining a step size and a model update direction. The model of the physical plant can be updated. The updating step can be dependent upon the step size. Another embodiment can include the steps of determining a Kalman gain and determining an error vector comprised of two entries weighted by a scalar parameter.Type: GrantFiled: March 31, 2004Date of Patent: May 5, 2009Assignee: University of Florida Research Foundation, Inc.Inventors: Deniz Erdogmus, Jose Carlos Principe, Yadunandana Nagaraja Rao
