Embodiment Construction

[0016] The present invention relates to a system and method for automatically creating collages from moving video. One way to represent a video sequence is to extract interesting keyframes from its content. Selection of key video frames is useful in many applications. For example, it is often desirable to extract and present a subset of video data that can convey an accurate and recognizable summary or synopsis of the video. Keyframe extraction algorithms are used to select a subset of the most informative frames from a video, with the goal of representing the most important content of a video using a limited number of frames. Keyframe extraction finds application in several broad areas of video processing, such as video summarization, creating chapter titles in DVDs, video indexing, and making photos from videos. A summary or synopsis can also facilitate video sharing or help users decide whether it's worth downloading or viewing the full video. Keyframe extraction is an a...

Abstract

A method and system for automated creation of collages from a video sequence is provided. The system and method dynamically extracts key frames from a video sequence, which are used to create the collages shown on a display. By changing the position of cursors, a new set of key frames is extracted and the content of the collage will change correspondingly reflecting the changes in the key frames selection. The method also includes user interface elements to allow a user to change the layout design (e.g., rotate, overlap, white space, image scaling) of the video frames on the collage. In addition, the method includes different ways for browsing the video sequence by using automatically detected semantic concepts in various frames as indexing points. Further, the method includes defining swiping attributes based on motion characteristics (e.g., zoom / pan, motion of object), audio activity, or facial expression for browsing the video sequence

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 62 / 367962, filed July 28, 2016, which is also incorporated herein by reference in its entirety. Background technique [0003] With the rapid development and lower cost of electronic mobile devices such as smartphones and new digital capture devices, video generated by device users is becoming more and more popular, just as high-volume video upload and Video viewing in social networks as shown. These large numbers of videos also pose a challenge for users to efficiently organize, manage and retrieve their videos. Additionally, many users store their image and video files directly on their mobile devices. Accordingly, there is a need to facilitate easy access and retrieval of user-generated content on mobile devices, allowing users to make better use of image and video content for sharing with friends and family, or for enjoying special events a...
