In accordance with an embodiment, a method of inserting advertisements into video content includes electronically receiving video content metadata from a content provider, matching the video content metadata to advertising content metadata to provide a first list of advertisements, filtering the first list of advertisements according to user preference data to determine a second list of advertisements, and transmitting the second list of advertisements to a user device for insertion into the video content. The video content metadata corresponds to video content being sent to a user device, and the advertising content metadata corresponds to advertising content.

A system and method for measuring the potential eyestrain felt by audiences while watching a 3D presentation, e.g., a stereoscopic motion picture, are provided. The eyestrain measurement system and method of the present disclosure is based on the measurement of disparity (or depth) and disparity transition of stereoscopic images of the 3D presentation. The system and method of the present disclosure provide for acquiring a first image and a second image from a first segment, estimating disparity of at least one point in the first image with at least one corresponding point in the second image, estimating disparity transition of a sequence of first and second images, and determining potential eyestrain felt while viewing the 3D presentation based on the disparity and the disparity transition of the sequence of the first and second images.

A system and method for marking a stereoscopic film with colors are provided. The system and method provides for marking a left image with a mark and a right image with a mark having complementary colors, wherein upon viewing, the marks are not visible under certain conditions. The system and method provide for acquiring a stereoscopic image, the stereoscopic image including a first image and a second image, applying a first mark to the first image in a predetermined location, the first mark having a first color, and applying a second mark to the second image in substantially the same predetermined location as in the first image, the second mark having a second color that is different than the first color of the first mark, wherein when viewed in three-dimensional mode, the first mark and the second mark combine into a single mark of one color.

A system and method for acquiring geometic information from images includes a modulated light source configured to provide light energy at a rate unperceivable by the human eye. A camera is configured to acquire images at a rate at which a differential pair of images is obtained such that one of the pair of images includes light from the light source and the other image of the pair does not include light from the light source. A comparison module is configured to compare the differential pair of images to create a depth map for three-dimension model creation.

A depth acquisition system utilizes at least three sensors with at least one sensor in a non-colinear configuration to increase depth information. This configuration provides both vertical and horizontal depth information to be combined to enhance image quality, especially in three-dimensional image gathering. Vertical sensor pairs aid in determining disparities for horizontal edges and make depth estimations for horizontal edges more accurate.

An embodiment is configured to calculate a perceptual masking factor at a pixel location at a block boundary of the image, calculate a parameter for a filter at the pixel location at the block boundary, and filter the image around the pixel location at the block boundary employing the filter with the calculated parameter. The perceptual masking factor is formed as a product of a background activity masking map and a luminance masking map. The filter includes a parameter that is selected in view of a quality of experience performance measure for the image at the pixel location at the block boundary of the image.
摘要:
A system and method for color correction of 3D images including at least two separate image streams captured for a same scene include determining three-dimensional properties of at least a portion of a selected image stream, the three-dimensional properties including light and surface reflectance properties, surface color, reflectance properties, scene geometry and the like. A look of the portion of the selected image stream is then modified by altering the value of at least one of the determined three-dimensional properties and, in one embodiment, applying image formation theory. The modifications are then rendered in an output 3D picture either automatically and/or according to user inputs. In various embodiments, corrections made to the selected one of the at least two image streams can be automatically applied to the other of the image streams.

Method and apparatus are provided for encoding a picture in a video sequence. An apparatus includes a pruning block identifier for identifying one or more original blocks to be pruned from an original version of the picture. The apparatus further includes a block replacer for generating a pruned version of the picture by respectively generating one or more replacement blocks for the one or more original blocks to be pruned. The apparatus also includes a metadata generator for generating metadata for recovering the pruned version of the picture. The metadata includes position information of the one or more replacement blocks. The apparatus additionally includes an encoder for encoding the pruned version of the picture and the metadata.
