Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing). The same techniques are equally applicable to video.
Image warping and lateral color correction
Color or grayscale images having optical elements induced geometric distortions can be corrected on individual color image component by creating correction image component having the complementary distortion; and applying the correction image component to the corresponding distorted color image component.

Low-latency virtual reality display system
InactiveUS9240069B1Enhance the virtual reality experienceEfficient and rapid rerendering reduces latencyImage renderingInput/output processes for data processingComputer graphics (images)Display device
A low-latency virtual reality display system that provides rapid updates to virtual reality displays in response to a user's movements. Display images generated by rendering a 3D virtual world are modified using an image warping approximation, which allows updates to be calculated and displayed quickly. Image warping is performed using various rerendering approximations that use simplified 3D models and simplified 3D to 2D projections. An example of such a rerendering approximation is a shifting of all pixels in the display by a pixel translation vector that is calculated based on the user's movements; pixel translation may be done very quickly, possibly using hardware acceleration, and may be sufficiently realistic particularly for small changes in a user's position and orientation. Additional features include techniques to fill holes in displays generated by image warping, synchronizing full rendering with approximate rerendering, and using prediction of a user's future movements to reduce apparent latency.

InactiveUS20070019882A1High quality imagingEasy to operateCharacter and pattern recognitionImage data processing detailsFacial regionReference image
A makeup simulation enables a high-quality simulation image quickly and simply. A first image generator portion 20 generates n transparency layer images in which the transparency of each pixel is normalized on the basis of n layer images in a use-reference image. A second image generator portion 30 generates n color converted layer images by applying a color conversion on a frame image using color components of the layer images. A mesh setting portion 50 sets a mesh in a facial region in each frame image and a makeup pattern image. An image deformer 60 calculates a difference between vertices of meshes in both images and deforms a makeup element image in each normalized transparency layer image based on this difference to fit in the facial region of the frame image. A synthesizer 70 synthesizes color converted layer images and each frame image by alpha blending.

InactiveUS20080170126A1Reduce motion blur degradationShort exposure timeTelevision system detailsColor television detailsPattern recognitionImaging quality
A method of improving image quality of a digital image is provided. In particular, the motion blur in an image taken in a long exposure time is reduced by dividing the exposure time into several shorter periods and capturing a series of images in those shorter periods. Among the images, one reference image is selected and the remaining images are registered in reference to the reference image by image warping, for example. After identifying the pixels in each of the remaining images and the corresponding pixels in the reference image, a weighting factor is assigned to each of the pixels in the remaining images based on the similarity in the pixel values between the remaining images and reference image. A weight average operation is carried out to sum the corresponding pixels in the reference and the remaining images to generate the final image.

A method for creating a 360 degree panoramic image from multiple images includes (1) computing a gross rotation error ΔR between a first image and a calculated first image rotated to be stitched to a last image, and (2) spreading the gross rotation error ΔR to each pixel on the panoramic image. Spreading the gross rotation error ΔR includes (1) computing a rotation angle θ0 and rotational axis n0 from the gross rotational error ΔR, (2) determining an angle α of each pixel, and (3) determining a compensation matrix Rc for each pixel using the following formula: Rc(α)=R(α / 2πθ0). Spreading the gross rotation error ΔR further includes (4) tracing a pixel on the panoramic image to a camera optical center of the images to form a first ray, (5) determining a second ray originating from the camera optical center that would be rotated by the compensation matrix Rc to coincide with the first ray, (6) tracing the second ray to a second pixel on one of the images, and (7) painting the first pixel with color values of the second pixel.
