Abstract

A video hosting web site receives uploaded video content and processes the video to determine ad surfaces. The ad surfaces comprise spatio-temporal regions of the video suitable for placement of advertisement such as background surfaces or other regions of low interest. The uploaded video and ad surfaces are stored to a video database that is accessible to viewers visiting the video hosting web site. When a shared video is requested, the video hosting site provides the requested video content together with the ad surfaces and advertisements. The advertisements are blended with the ad surfaces in the video at playtime so that the advertisements appear as part of the video scene. This allows the video hosting web site to present advertisements to the viewer without significantly distracting the viewer from the requested content.

Claims (90)

1. A computer-implemented method for placing advertisements in video, comprising:

receiving via a web-based interface, a video from a content provider client device;

detecting a scene of the video comprising a plurality of frames between consecutive scene boundaries;

segmenting each frame of the scene into a foreground image and a background image;

averaging pixels of the background images across the plurality of frames to determine an average background image for the scene;

processing the video to automatically determine ad surface parameters based on appearance characteristics of the average background image, the ad surface parameters defining an ad surface comprising a spatio-temporal region of the video, the ad surface suitable for placement of an advertisement such that when the advertisement is blended with the ad surface, the advertisement appears as part of an object depicted in the video;

storing the video content and the ad surface parameters to a computer readable storage;

receiving a request from a viewer client device for the stored video;

transmitting the video to the viewer client device together with the ad surface parameters;

selecting an advertisement to deliver to the viewer client device for placement on the ad surface; and

transmitting the advertisement to the viewer client device, wherein the viewer client device processes the advertisement and the video in accordance with the ad surface parameters to blend the advertisement with the ad surface.

2. The method of claim 1 , wherein the advertisement is selected based on stored preferences of a user of the viewer client device.

3. The method of claim 1 , wherein the advertisement is selected based on stored preferences of a content provider that provided the video.

4. The method of claim 1 , wherein the advertisement is selected based on stored preferences of an advertiser that provided the advertisement.

5. The method of claim 1 , further comprising:

transmitting a representation of the ad surface to a reviewer client device;

modifying the ad surface parameters responsive to receiving modifications from the reviewer client device; and

storing the modified ad surface parameters to the computer readable storage medium.

6. The method of claim 1 , wherein the spatio-temporal region suitable for placement of the advertisement comprises a surface of a background object in the video.

7. The method of claim 1 , wherein the spatio-temporal region suitable for placement of the advertisement comprises a time portion of the video having a start time and an end time.

8. The method of claim 1 , wherein processing the video to automatically determine the ad surface parameters further comprises:

computing a texture map based on the average background image;

computing an edge map based on the average background image; and

determining the ad surface parameters based on the texture map and the edge map.

9. The method of claim 8 , wherein determining the ad surface parameters based on the texture map and the edge map comprises:

detecting polygons in the average background image based on the edge map; and

refining the detected polygons in the average background image based on the texture map.

10. The method of claim 8 , wherein determining the ad surface parameters based on the texture map and the edge map comprises:

detecting polygons in the average background image based on the texture map; and

refining the detected polygons in the average background image based on the edge map.

11. The method of claim 1 , further comprising:

receiving a purchase request for the ad surface from an advertiser, wherein the ad surface has a cost based on a predicted effectiveness of displaying an advertisement on the ad surface; and

assigning the ad surface to the advertiser responsive to the purchase request.

12. The method of claim 1 , further comprising:

determining a computational capacity of the viewer client device; and

selecting, responsive to the determined computational capacity, an blending technique for processing the advertisement and the video to blend the advertisement with the ad surface; and

providing an indication of the selected blending technique to the viewer client device, wherein the viewer client device is adapted to use the indicated blending technique to blend the advertisement with the ad surface.

13. The method of claim 1 , wherein the viewer client device processes the advertisement and the video to blend the advertisement with the ad surface according to blending parameters, further comprising:

detecting a change in the ad surface or the advertisement; and

adjusting the blending parameters responsive to the detected change.

14. A non-transitory computer readable storage medium storing computer executable instructions for placing advertisements in video, the instructions when executed cause a processor to execute steps including:
