US Classification:

382154, 382224

Abstract:

An image converter compiles three-dimensional content into a data store, identifies a number of stereo image pairs from the three-dimensional content, computes a depth map for each of the stereo image pairs from the three-dimensional content, and partitions the stereo image pairs in the data store into multiple categories. The image converter determines a depth cue for each of the categories based on the depth map for each of the stereo image pairs in each category. The image converter computes a depth map for a category associated with a two-dimensional input image based on the determined depth cue and renders a three-dimensional output image from the two-dimensional input image using the depth map for the category.

US Classification:

345419

Abstract:

An image converter receives a two-dimensional image to be converted to a first three-dimensional image. The image converter computes a feature-to-depth mapping function based on an approximate depth map associated with a second three-dimensional image. The image converter applies the feature-to-depth mapping function to a plurality of pixels of the two-dimensional image to determine a depth value for each of the plurality of pixels and generates the first three-dimensional image based on the depth values for the plurality of pixels of the two-dimensional image.

Abstract:

A two-dimensional image to be converted to a first three-dimensional image may be received. A second three-dimensional image that is visually similar to the two-dimensional image that is to be converted may be identified. A feature-to-depth mapping function may be computed for the first three-dimensional image by using an approximate depth map of the second three-dimensional image that is visually similar to the two-dimensional image that is to be converted. The feature-to-depth mapping function may be applied to a plurality of pixels of the two-dimensional image to determine a depth value for the plurality of pixels of the two-dimensional image. The first three-dimensional image may be generated based on the depth values for the plurality of pixels of the two-dimensional image.

Abstract:

An image processing system for recognizing the scene type of an input image generates an image distance metric from a set of images. The image processing system further extracts image features from the input image and each image in the set of images. Based on the distance metric and the extracted image features, the image processing system computes image feature distances for selecting a subset of images. The image processing system derives a scene type from the scene type of the subset of images. In one embodiment, the image processing system is a cloud computing system.
