Abstract

Provided in the present disclosure are a method and apparatus for image processing, and a device and a medium. The method comprises: acquiring a first fused image frame and a second fused image frame, and sequentially displaying the first fused image frame and the second fused image frame. By means of the method provided in the present disclosure, a fused image frame obtained on the basis of the fusion of an image frame and a grayscale image frame can be displayed, and the grayscale image frame is obtained on the basis of performing graying processing on a corresponding area in an adjacent frame of the image frame, such that the display brightness can be compensated for and the power consumption can be reduced, such that the displayed fused image frame is brighter than before, thereby making the final brightness perceived by human eyes brighter. In addition, by means of the method provided in the present disclosure, grayscale image frames are subjected to graying processing and are then further subjected to smoothing processing, such that content details or contours in the grayscale image frames can be removed, thus avoiding content crosstalk during subsequent brightness compensation.

Abstract

An autostereoscopic display is calibrated prior to use. During calibration, processing circuitry can receive an image, captured within a field of view of the autostereoscopic display, of at least some of a calibration pattern as displayed on the autostereoscopic display. The image can correspond to a light pattern at an image location that is spaced apart from the autostereoscopic display. The calibration pattern can optionally include two different calibration subpatterns having different colors. The processing circuitry can determine, from the image, a plurality of physical parameter values that quantify part-to-part variations and misalignments of elements of the autostereoscopic display. The physical parameter values can include a single value of a pitch of a parallax-generating optic and a single value of a rotational misalignment between a display panel and the parallax-generating optic. The processing circuitry can store data representing the physical parameter values.

Abstract

An autostereoscopic display is calibrated prior to use. During calibration, processing circuitry can receive far-field images of a calibration pattern, captured at locations over an operational area of the autostereoscopic display. The processing circuitry can determine, for each far-field image, location-dependent intermediate quantities, such as a location-dependent far-field angular phase central value, a location- dependent separation between a display panel and a parallax-generating optic, and a location-dependent refractive index of a material disposed between the display panel and the parallax-generating optic. The processing circuitry can determine, from the location- dependent intermediate quantities and the locations, physical parameter values that quantify part-to-part variations. The physical parameter values can include a lateral misalignment between the display panel and the parallax-generating optic, an angular misalignment between the display panel and the parallax-generating optic, and a pitch of the parallax-generating optic.

Systems and methods are directed to a camera system configured to capture a multiview image of an object along an arc. Each camera in the camera system may correspond to a common field of view. In addition, a computing system coupled to the camera system may calculate a target camera baseline based on a first value and a second value, and dynamically adjust an inter-camera capture distance to match the target camera baseline. The first value may indicate the common field of view and the second value may indicate a distance between the camera system and the object.

Abstract

Systems and methods are directed to generating a three-dimensional (3D) model of a first image set. The first image set (e.g., input image set) corresponds to different viewing angles of an object that is subject to 3D modeling. A volumetric density function is generated from the first image set. A second image set (e.g., a textured image set) is generated from the volumetric density function and from a predefined color function. The first image set is blended with the second image set to generate a third image set (e.g., an image set with temporary textures). To generate the 3D model, a 3D surface model is generated from the third image set. In addition, a texture map of the 3D surface model is generated from the first image set. A computing system is configured to render the 3D surface model and texture map for display.

Systems and methods are directed to multiview format detection. A multiview image that comprises a plurality of tiled view images is accessed. A cross-correlation map from the multiview image may be generated by autocorrelating the multiview image with a shifted copy of the multiview image. The cross-correlation map may be sampled at a plurality of predefined locations of the cross-correlation map to identify a set of cross-correlation values. A multiview format of the multiview image may be detected by classifying a feature set of the multiview image that comprises the set of cross-correlation values. The multiview image may be configured to be rendered on a multiview display based on the multiview format.

Abstract

Systems and methods are directed to streaming multiview video from a sender system to a receiver system. A sender system may capture an interlaced frame of a multiview video rendered on a multiview display of the sender client device. The interlaced frame may be formatted as spatially multiplexed views defined by a multiview configuration having a first number of views. The sender system may deinterlace the spatially multiplexed views of the interlaced frame into separate views. The sender system may concatenate the separated views to generate a tiled frame of a tiled video. The sender system may transmit the tiled video to a receiver client device, where the tiled video is compressed. The receiver system may decompress and interlace the views of the tiled video into streamed interlaced frames and render the streamed interlaced frames on a multiview display of the receiver system.

Abstract

Systems and methods are directed to generating a three-dimensional (3D) model of a first image set. The first image set (e.g., input image set) corresponds to different viewing angles of an object that is subject to 3D modeling. A volumetric density function is generated from the first image set. A second image set (e.g., a textured image set) is generated from the volumetric density function and from a predefined color function. The first image set is blended with the second image set to generate a third image set (e.g., an image set with temporary textures). To generate the 3D model, a 3D surface model is generated from the third image set. In addition, a texture map of the 3D surface model is generated from the first image set. A computing system is configured to render the 3D surface model and texture map for display.

Abstract

A multibeam backlight and multiview display employ a multibeam element having a shaped edge with a shape configured to disperse spurious diffraction components. The multibeam backlight includes a light guide configured to guide light and a plurality of multibeam elements spaced apart from one another across the light guide, the multibeam element plurality being configured to scatter out the guided light as emitted light. A multibeam element of the multibeam element plurality includes a shaped edge oriented orthogonal to the propagation direction and having shape of the shaped edge of the multibeam element is configured to disperse spurious diffraction components in the emitted light associated with an interaction between the guided light and the multibeam element. The multiview display includes a light valve array configured to modulate the emitted light as a multiview image having a plurality of views in a similar plurality of different view directions.
