TRANSITION BETWEEN BINOCULAR AND MONOCULAR VIEWS

Номер: US20180182175A1
Автор: Briggs Forrest Samuel, Cabral Brian Keith
Принадлежит:

An image processing system is designed to generate a canvas view that transitions between binocular views and monocular views. Initially, the image processing system receives top/bottom images and side images of a scene and calculates offsets to generate synthetic side images for left and right view of a user. To transition between binocular views and monocular views, the image processing system first warps top/bottom images onto corresponding synthetic side images to generate warped top/bottom images, which realizes the transition in terms of shape. The image processing system then morphs the warped top/bottom images onto the corresponding synthetic side images to generate blended images for left and right eye views with the blended images. The image processing system creates the canvas view which transitions between binocular views and monocular views in terms of image shape and color based on the blended images. 1. A method comprising:identifying a horizontal angle and vertical angle of view for a portion of a display for an eye, the horizontal angle and vertical angle representing a portion of a canvas for view by the eye;identifying an overlapping portion of a top image and an image corresponding to a view for the eye;determining an optical flow; andapplying the optical flow to the top image based on the vertical angle.2.

Virtual Parallax to Create Three-Dimensional Appearance

Номер: US20210349609A1
Автор: Anderson Ross W., Bockert Jan H., Byrod Gunnar Martin, Hedberg Johan V.
Принадлежит: Apple Inc.

In some implementations, a computing device can simulate a virtual parallax to create three dimensional effects. For example, the computing device can obtain an image captured at a particular location. The captured two-dimensional image can be applied as texture to a three-dimensional model of the capture location. To give the two-dimensional image a three-dimensional look and feel, the computing device can simulate moving the camera used to capture the two-dimensional image to different locations around the image capture location to generate different perspectives of the textured three-dimensional model as if captured by multiple different cameras. Thus, a virtual parallax can be introduced into the generated imagery for the capture location. When presented to the user on a display of the computing device, the generated imagery may have a three-dimensional look and feel even though generated from a single two-dimensional image. 1. A method , comprising:obtaining, by a computing device, a first image and a second image;for each first pixel in the first image, determining, by the computing device, a corresponding second pixel in the second image;obtaining, by the computing device, pixel quality scores for each first pixel and corresponding second pixel;for one or more first pixels, comparing, by the computing device, pixel quality scores for the one or more first pixels to pixel quality scores for one or more corresponding second pixels;for each of the one or more first pixels, selecting, by the computing device, between the first pixel and the corresponding second pixel based on the comparison; andgenerating, by the computing device, a composite image based on selected pixels from the first image and the second image.2.

An image identification apparatus includes an extraction unit, an excluding unit, and an identification unit. The extraction unit extracts lines from an image. The exclusion unit excludes from objects to be identified a boundary delimiting an entire area of the image among the extracted lines. The identification unit identifies as an object multiple lines that are among the extracted lines and that are not excluded by the exclusion unit if the multiple lines are connected to each other.

Methods and apparatus to capture photographs using mobile devices

Номер: US11336819B2
Автор: Antonio HURTADO GARCÍA, Carlos Barrales Ruiz, Diego GARCÍA MORATE, Javier Tovar Velasco
Принадлежит: Nielsen Co US LLC

Methods and apparatus to capture photographs using mobile devices are disclosed. An example apparatus includes a photograph capturing controller to capture a first photograph. The apparatus further includes a blurriness analyzer to determine a probability of blurriness of the first photograph. The probability of blurriness is based on an analysis of a portion of the first photograph, the portion excluding a region of the first photograph associated with an auto-focus operation. The example apparatus also includes a photograph capturing interface to prompt a user to capture a new photograph to replace the first photograph when the probability of blurriness exceeds a blurriness threshold.

이 기술은 이미지가 캡쳐될 때 보여지는 공통적 패턴들에 기초하여 클러스터들로 조직화되는 이미지를 네비게이션하는 것에 관한 것이다. 예를 들어, 미리 결정된 패턴을 만족시키는 캡쳐된 이미지들의 세트가 결정될 수 있다. 캡쳐된 이미지들의 세트 내의 이미지들은 상기 미리 결정된 패턴에 따라 하나 이상의 클러스터들로 그룹화될 수 있다. 상기 하나 이상의 클러스터들 중 제1 클러스터를 디스플레이하기 위한 요청이 수신될 수 있고, 이에 응답하여, 상기 요청된 제1 클러스터로부터 제1 캡쳐된 이미지가 선택될 수 있다. 그 다음, 선택된 제1 캡쳐된 이미지가 디스플레이될 수 있다. This technique relates to navigating an image organized into clusters based on common patterns seen when the image is captured. For example, a set of captured images that satisfy a predetermined pattern can be determined. Images in the set of captured images may be grouped into one or more clusters according to the predetermined pattern. A request to display a first one of the one or more clusters may be received, and in response, a first captured image from the requested first cluster may be selected. The selected first captured image can then be displayed.

Periphery monitoring device for work machine

Номер: US10044933B2
Автор: Moritaka OOTA, Yoichi Kowatari, Yoshihiro Inanobe
Принадлежит: HITACHI CONSTRUCTION MACHINERY CO LTD

A periphery monitoring device for a work machine includes imaging devices that capture an image of the surroundings of the work machine. An overhead view image is generated from the surroundings of the work machine based upon upper view-point images of the image devices. When generating an overhead view image of an overlap region of first and second upper view-point images relating to the images captured by the first and second imaging devices, the overhead view image generating unit, based upon a height of a virtual monitoring target, sets at least one of a first region in which the first upper view-point image is displayed and a second region in which the second upper view-point image is displayed, and also sets a third region in which a composite display image based upon the first and second upper view-point images is displayed.
