Visual and audio recognition for scene change events

摘要

Various embodiments describe systems and methods for utilizing a reduced amount of processing capacity for incoming data over time, and, in response to detecting a scene-change-event, notify one or more data processors that a scene-change-event has occurred, and cause incoming data to be processed as new data. In some embodiments, an incoming frame can be compared with a reference frame to determine a difference between the reference frame and the incoming frame. The reference frame may be correlated to a latest scene-change-event. In response to a determination that the difference does not meet one or more difference criteria, a user interface or at least one processor of the computing device can be notified to reduce processing of incoming data over time. In response to a determination that the difference meets the one or more difference criteria, the user interface or the at least one processor can be notified that a scene-change-event has occurred. Incoming data to the computing device is then treated as new and processed as those under an active condition. The current incoming frame can be selected as a new reference frame for detecting next scene-change-event.

主权项

1. A computing device, comprising:
a camera; at least one processor; and memory including instructions that, when executed by the at least one processor, cause the computing device to:
acquire a series of frames of content using the camera;select a reference frame from the series of frames of content;acquire a subsequent frame of content using the camera;determine a first feature point that is included in a set of feature points represented in the reference frame;determine a first location associated with the first feature point represented in the reference frame;determine a second location associated with the first feature point represented in the subsequent frame;determine a change between the first location and the second location;determine that the change is below a motion threshold; andcause the at least one processor to reduce processing of incoming frames of content.
