  • Patent number: 10510174
    Abstract: Technologies related to generating mixed reality video are described herein. Video frames capture a human, and positions of skeletal features of the human are estimated based solely upon the video frames. A mixed reality video is generated, wherein the mixed reality video includes the video combined with an animation, wherein the animation is based upon movement of the human in the video as represented by the estimated positions of the skeletal features of the human.

  • Patent number: 10257417
    Abstract: A method and an apparatus for generating panoramic images are presented. The method includes receiving a set of consecutive image frames. A portion of a first image frame is extracted to configure an intermediate panoramic image. The intermediate panoramic image is augmented by stitching image frame portions to the intermediate panoramic image. The image frame portions are selected from individual image frames in a subset of image frames including consecutive image frames from a second image frame to a penultimate image frame. Each image frame portion is selected based on a sharpness measure and an overlap measure associated with the respective individual image frame. The overlap measure is determined based on a comparison of the respective individual image frame with a current state of the intermediate panoramic image. A portion of a last image frame is stitched to the augmented intermediate panoramic image to configure the panoramic image.

  • Patent number: 10129485
    Abstract: An electronic device and a method for generating a high dynamic range (HDR) image frame. The method includes obtaining at least two digital image frames, where each of the at least two digital image frames is captured with a different exposure setting. The method includes generating, by a processor, a radiance map from the at least two digital image frames, and performing image fusion of the at least two digital image frames to generate a fused image. Further, the method includes combining, by the processor, color values of image channels of the fused image and the radiance map to generate the HDR image frame.

  • Patent number: 10097766
    Abstract: According to one aspect, there is provided an apparatus comprising at least one processing unit and at least one memory. The at least one memory stores program instructions that, when executed by the at least one processing unit, cause the apparatus to control a first set of pixels of an image sensor for exposure of a scene for a camera viewfinder, the image sensor having at least two sets of pixels enabling different exposure times, and control a second set of pixels of the image sensor for exposure analysis of the scene for images to be captured for a multi-exposure image.

  • Patent number: 9401027
    Abstract: A method, apparatus and computer program product are provided to facilitate scene segmentation from focal stack images. The method may include receiving a set of focal stack images, calculating a focal measure for each of a plurality of pixels of the set of focal stack images, and grouping each of a plurality of pixels for which the focal measure was calculated into a plurality of super pixels. The method may also include calculating a focal measure for each of the plurality of super pixels, segmenting a respective focal stack image based on the focal measure of each of the plurality of super pixels, calculating a color probability for each of the plurality of super pixels, and segmenting each focal stack image based on color probability of each of the plurality of super pixels.
