  • Patent number: 10752158
    Abstract: A pulsed laser may illuminate a scene that is obscured by dense, dynamic and heterogeneous fog. Light may reflect back to a time-resolved camera. Each pixel of the camera may detect a single photon during each frame. The imaging system may accurately determine reflectance and depth of the fog-obscured target, without any calibration or prior knowledge of the scene depth. The imaging system may perform a probabilistic algorithm that exploits the fact that times of arrival of photons reflected from fog have a Gamma distribution that is different than the Gaussian distribution of times of arrival of photons reflected from the target. The probabilistic algorithm may take into account times of arrival of all types of measured photons, including scattered and un-scattered photons.

  • Patent number: 10410327
    Abstract: This disclosure relates to techniques for synthesizing out of focus effects in digital images. Digital single-lens reflex (DSLR) cameras and other cameras having wide aperture lenses typically capture images with a shallow depth of field (SDOF). SDOF photography is often used in portrait photography, since it emphasizes the subject, while deemphasizing the background via blurring. Simulating this kind of blurring using a large depth of field (LDOF) camera may require a large amount of computational resources, i.e., in order to simulate the physical effects of using a wide aperture lens while constructing a synthetic SDOF image. However, cameras having smaller lens apertures, such as mobile phones, may not have the processing power to simulate the spreading of all background light sources in a reasonable amount of time. Thus, described herein are techniques to synthesize out-of-focus background blurring effects in a computationally-efficient manner for images captured by LDOF cameras.

    Abstract: A method for image de-blurring includes estimating an intermediate image L by marking and constraining an edge region and a smooth region in an input image; estimating a blur kernel k by extracting salient edges from the intermediate image L, wherein the salient edges have scales greater than those of the blur kernel k; and restoring the input image to a clear image by performing non-blind deconvolution on the input image and the estimated blur kernel k. Imposing constraints on the edge region and the smooth region allows the intermediate image to maintain the edge while effectively removing noise and ringing artifacts in the smooth region. The use of the salient edges in the intermediate image L enables more accurate blur kernel estimation. Performing non-blind deconvolution on the input image and the estimated blur kernel k restores the input image to a clear image achieving desired de-blurring effect.

  • Patent number: 10218968
    Abstract: A gaze contingent display technique for providing a human viewer with an enhanced three-dimensional experience not requiring stereoscopic viewing aids. Methods are shown which allow users to view plenoptic still images or plenoptic videos incorporating gaze-contingent refocusing operations in order to enhance spatial perception. Methods are also shown which allow the use of embedded markers in a plenoptic video feed signifying a change of scene incorporating initial depth plane settings for each such scene. Methods are also introduced which allow a novel mode of transitioning between different depth planes wherein the user's experience is optimized in such a way that these transitions trick the human eye into perceiving enhanced depth. This disclosure also introduces a system of a display device which comprises gaze-contingent refocusing capability in such a way that depth perception by the user is significantly enhanced compared to prior art.

  • Patent number: 10165205
    Abstract: An image processing method is provided. The image sensor is controlled to output the merged image. The depth-of-field area is identified based on the merged image. The image sensor is controlled to output the color-block image. A first part of the color-block image within the depth-of-field area is converted into a first simulation image using a first interpolation algorithm. The second part of the color-block image outside the depth-of-field area is converted into a second simulation image using a second interpolation algorithm. The first simulation image and the second simulation image are merged to generate a simulation image corresponding to the color-block image.

  • Patent number: 10152825
    Abstract: Provided are mechanisms and processes for augmenting multi-view image data with synthetic objects using inertial measurement unit (IMU) and image data. In one example, a process includes receiving a selection of an anchor location in a reference image for a synthetic object to be placed within a multi-view image. Movements between the reference image and a target image are computed using visual tracking information associated with the multi-view image, device orientation corresponding to the multi-view image, and an estimate of the camera's intrinsic parameters. A first synthetic image is then generated by placing the synthetic object at the anchor location using visual tracking information in the multi-view image, orienting the synthetic object using the inverse of the movements computed between the reference image and the target image, and projecting the synthetic object along a ray into a target view associated with the target image.

  • Patent number: 10079025
    Abstract: A method of modification of audio data to improve the quality of the audio modification or reconstruction or improves the speed of such reconstruction or modification and produces more realistic audio data. Realistic audio data is audio data that is generated in natural events like talking or singing or a vehicle passing by and is not generated only by artificially constructing audio data like in a synthesizer. This will lead to audio data that will be perceived more likely as natural or unmodified audio signal when being played back to human beings. The method involves modification of some part of transformed audio data, especially phase data.
