摘要： A system and method for reducing streak artifacts in a multiplanar reconstruction image are provided. The method may include: retrieving a first image volume from image data, the first image volume including multiple images, at least one of which includes a streak artifact including multiple streaks of a streak width along a first direction; determining a second image volume and a third image volume based on the first image volume; determining an initial error image volume based on the second image volume and the third image volume; determining a revised error image volume based on the initial error image volume; smoothing the revised error image volume to generate a final error image volume; correcting the first image volume according to the final error image volume; and, generating, based on the corrected first image volume, a corrected image volume.

摘要： A system and method are provided for optimizing histogram cumulative distribution function curves. In use, a first image is received and divided into two or more pixel regions. For at least one of the two or more pixel regions, a first histogram is computed, and based on the first histogram, at least one cumulative distribution function is computed for the at least one of the two or more pixel regions. Next, based on the at least one cumulative distribution function, two or more curve fit coefficients are extracted and interpolated. Further, an interpolated cumulative distribution function is created based on the interpolation and the interpolated cumulative distribution function is applied to the at least one of the two or more pixel regions.

摘要： The invention relates to a method for determining a transition between two display images. A two-dimensional initial image is mapped by means of a first and a second mapping function respectively onto a first and a second mapped image and the first and second mapped images are mapped respectively onto a first display image. The initial image is mapped by means of an interpolated mapping function onto an interpolated mapped image in the model space, wherein the interpolated mapped image is determined by interpolation of the first mapped image and the second mapped image as a function of an interpolation parameter. The initial image, mapped by means of the interpolated mapping function onto the interpolated mapped image, is mapped onto an interpolated display image which transitions from the first display image to the second display image through variation of the interpolation parameter.

摘要： An image processing method is provided. The method is configured to process the color-block image output by the image sensor. The face region of the color-block image is determined. A part of the color-block image beyond the face region is converted into a first simulation image using a first interpolation algorithm. A part of the color-block image within the face region is converted into a second simulation image using a second interpolation algorithm. The complexity of the second interpolation algorithm is less than that of the first interpolation algorithm. The first simulation image and the second simulation image are merged into a simulation image corresponding to the color-block image. An image processing apparatus and an electronic device are provided. With the image processing method, the image processing apparatus and the electronic device, distinguishability and resolution of the image are improved, and time required for processing the image is reduced.

摘要： A method, a head-up display and a display system for the perspective transformation and displaying of rendered image content, as well as a corresponding vehicle, are provided. In the perspective transformation and outputting method, the image content to be displayed is subdivided into a plurality of tiles, and the individual tiles are each transformed in perspective using perspective transformation. The individual tiles that have been transformed in perspective are then combined to form a transformed image content, and the image content transformed in perspective is projected onto a projection area of the head-up display or displayed on a display unit.

摘要： A system includes one or more processors and a memory that stores a generative adversarial network (GAN). The one or more processors are configured to receive a low resolution point cloud comprising a set of three-dimensional (3D) data points that represents an object. A generator of the GAN is configured to generate a first set of generated data points based at least in part on one or more characteristics of the data points in the low resolution point cloud, and to interpolate the generated data points into the low resolution point cloud to produce a super-resolved point cloud that represents the object and has a greater resolution than the low resolution point cloud. The one or more processors are further configured to analyze the super-resolved point cloud for detecting one or more of an identity of the object or damage to the object.

摘要： Embodiments relate to a patch processor that warps patches of input image data. The patch processor includes a patch direct memory access (DMA) circuit that obtains the patches via direct memory access. The patch processor includes a patch warper circuit that generates warped patches by processing the patches by performing interpolation in a raster scan fashion using a set of coordinates, for example. The patch warper circuit may also process pixels of the patches using an adder or subtractor circuit. In addition, the patch warper circuit may interleave warped patches of different image channels such as RGB or YCbCr colors. The patch warper circuit can also double-buffer the patches and warped patches.

摘要： A vertex processing device applied in an image processing system having an image capture module is disclosed. The image capture module generates camera images. The vertex processing device comprises a coefficient interpolation unit and a coordinate modifying unit. The coefficient interpolation unit generates an interpolated warping coefficient for each camera image with respect to each vertex from a vertex list based on n number of warping coefficients and its original texture coordinates in each camera image. The coordinate modifying unit calculates modified texture coordinates in each camera image for each vertex according to the interpolated warping coefficient and its original texture coordinates in each camera image. The vertex list comprises vertices with data structures that define vertex mapping between the camera images and a panoramic image. The n number of warping coefficients correspond to n number of overlap regions in the panoramic image.
