Identification and de-identification within a video sequence
First Claim
1. A method for de-identifying a video sequence, comprising:
- capturing, in a video capture device, a video sequence comprising a plurality of individual frames, the plurality of individual frames including images of a desired action;
designating, by a processor, one or more frames of the plurality of individual frames as comprising a sequence of the desired action, wherein at least one of the plurality of individual frames is non-designated;
identifying a first portion of the one or more designated frames to remain visible, wherein the first portion comprises the desired action;
de-identifying a second portion of the one or more designated frames and de-identifying the at least one non-designated frame so that the first portion comprising the desired action remains visible; and
de-identifying a further portion of the first portion of the one or more designated frames determined to include one or more faces other than faces of one or more users.

Abstract
A method and system for de-identifying a video sequence are provided. The method may include the steps of capturing a video sequence, comprising a number of individual frames, including one or more users performing one or more actions, and using activity recognition to recognize one of the one or more actions. One or more of the plurality of frames may be defined as comprising the recognized one or more actions, and a portion of the one or more of the plurality of frames may be identified to remain visible. The non-identified portions of the one or more of the plurality of frames and the non-defined frames may be de-identified. This method may be applied to the determine of whether a user has ingested a medication pill.

10. A method for de-identifying a video sequence of a user performing a desired activity, comprising the steps of:
-
capturing a first video sequence in a video capture device, the first video sequence comprising a plurality of individual frames, the plurality of individual frames including images of one or more users performing a first desired activity; designating, by a processor, one or more frames of the plurality of individual frames as comprising the first desired activity, wherein at least one frame is non-designated; identifying a first portion of the one or more designated frames to remain visible, wherein the first portion comprises the first desired activity; and de-identifying a second portion of the one or more designated frames and de-identifying the at least one non-designated frame so that the first portion comprising the first desired activity remains visible; and de-identifying a further portion of the first portion of the one or more designated frames determined to include one or more faces other than faces of the one or more users. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for de-identifying a video sequence of a user performing a desired activity, the system comprising:
-
a video capture device operable to capture a video sequence comprising a plurality of individual frames, the plurality of individual frames including images of one or more users performing a desired activity; and a processor associated with the video capture device operable to perform activity recognition on the captured video sequence to recognize the desired activity by; determining, through object recognition, an identity of a first object for a first plurality of frames of the captured video sequence, determining, through object recognition, an identity of a second object and its surroundings in a second plurality of frames of the captured video sequence, designating one or more frames of the captured video sequence as comprising recognized action of the desired activity, wherein at least one frame is non-designated, identifying a first portion of the one or more designated frames of the captured video sequence to remain visible, wherein the first portion comprises a recognized placement of the second object, de-identifying a second portion of the one or more designated frames and de-identifying the at least one non-designated frame so that the first portion remains visible, and de-identifying a further portion of the first portion of the one or more designated frames of the captured video sequence determined to include one or more faces other than faces of the one or more users performing the desired activity. - View Dependent Claims (19, 20)
