Abstract: Embodiments of the present disclosure provide a method for controlling a virtual reality display device, wherein the virtual reality display device includes a display, an optical system, and a movement controller. In this method, an anti-distortion image is generated based on the original image according to distortion parameters of the optical system. The anti-distortion image includes an effective image area and an invalid image area, wherein the effective image area includes image information of the original image. The movement control information is written into the invalid image area, and the movement control information is used by the movement controller to control the movement of the display. The anti-distortion image is provided to the virtual reality display device.

Abstract: An image processing method is disclosed. The image processing method may include: partitioning an original gridded image to obtain a plurality of regional grid images, wherein the regional grid images are distributed along a direction away from a geometric center of the original gridded image (S300); and adjusting grid vertices of the regional grid images based on anti-distortion parameters to obtain a plurality of regional correction grid images forming a grid correction image (S400). A grid density of each of the regional correction grid images may be smaller than or equal to a grid density of a corresponding regional grid image, and the grid density of each of the plurality of the regional correction grid images may gradually increase along the direction away from the geometric center of the original gridded image.

Abstract: A computer-implemented method of detecting a foreign object on a background object in a sample image is provided. The computer-implemented method includes extracting image features of the sample image; detecting a salient region in the sample image; and segmenting the salient region to determine a contour of a foreign object region based on results of segmenting the salient region. Segmenting the salient region is performed by an automatic Grabcut operation without user interaction.
