Abstract:
In some embodiments, an apparatus includes a memory and a processor. The processor is configured to receive a set of images associated with a video recorded by a moving or a non-moving camera. The processor is configured to detect a structure of a region of interest from a set of regions of interest in an image from the set of images. The processor is configured to classify the structure into a geometric class from a set of predefined geometric classes using machine learning techniques. The processor is configured to alter the region of interest to generate an altered image when the geometric class is associated with an identity of a person, such that privacy associated with the identity of the person is protected. The processor is configured to send the altered image to a user interface or store the altered image in a standardized format.
Abstract:
A method for adjusting power consumption of playing back a media content is presented. The method comprises receiving media content having first and second media segments; playing back the first media segment with a first number of frames different from a second number of frames in the first media segment; and playing back the second media segment, wherein the first number is determined according to average power of the first media segment and average power of the media content.
Abstract:
Method (1000) of providing power saving information for media content is described including receiving (1010) media content comprising a plurality of media segments, determining (1020) a power consumption indicator for a media segment of the plurality of media segments, determining (1030) power saving information for the media segment based on the power consumption indicator for the media segment and providing (1040) the power saving information. Method (1100) of receiving power saving information for media content is described including receiving (1110) power saving information for a media segment in a media content, applying (1120) said power saving information to the media segment to generate a power adjusted media content and providing (1130) the power adjusted media content. Equivalent apparatuses for providing (110, 200) and for receiving (120, 200, 250) power saving information for media content are also provided.
Abstract:
A system (42, 115) and method (22, 32) that enables a user (52) to interact with an advertisement and express an opinion about it. Such user interactivity is provided through a Hybrid Broadcast Broadband TV, HbbTV, auto-start application, which is associated with an advertisement event and a Uniform Resource Locator, URL, to the auto-start application is carried in a Digital Video Broadcast Application Information Table, DVB AIT, of the broadcast transport stream (75, 90) associated with the TV program or channel where the advertisement is to be shown. The hybrid terminal (44) receiving the AIT-containing transport stream retrieves the auto-start application using the URL before the corresponding ad is played back to the viewer. When the ad is played, the retrieved application is simultaneously launched. The application's UI (100, 102) allows the user to interact with the ad or express an opinion about the content of the ad. A user's interaction with an advertisement can be tracked as well.
Abstract:
Method comprising, for each pixel, obtaining a pixel expansion exponent value (E'(p)) by low pass filtering luminance values of colors of pixels in its spatial neighborhood, obtaining a pixel luminance-enhancement value (Y enhance (p)) by extraction of high frequencies of luminance values of colors of pixels in its spatial neighborhood, and then inverse tone mapping the luminance (Y(p)) according to the equation Y exp (p) = Y(p) E'(p) x [Y enhance (p)] c .
Abstract:
User adaptive 3D video rendering is disclosed. Content may be displayed on a display. A user's position relative to the display and/or a user's direction of view relative to the display may be determined. A user interface of the content may be adjusted based on the user's position and/or the user's direction of view. Adjusting a user interface may include adjusting the perspective of a view of the content displayed on the display. Adjusting a perspective of the view may include determining an adjusted view of the content from available views based on the user's position and/or the user's direction of view. The available views of the content may be requested from a server. A subset of the available views may be received from the server, for example, based on the user's position and/or the user's direction of view. The adjusted view may be displayed on the display.
Abstract:
A display control unit of an illustrative embodiment simultaneously displays a plurality of cut-out images cut out from respective wide-angle moving image clips.
