摘要:
A super-resolution enhanced image generating system is described for generating a super-resolution-enhanced image from an image of a scene, identified as image g0, comprising a base image and at least one other image gi, the-system comprising an initial super-resolution enhanced image generator, an image projector module and a super-resolution enhanced image estimate update generator module. The initial super-resolution enhanced image generator module is configured to use the image g0 to generate a super-resolution enhanced image estimate. The image projector module is configured to selectively use a warping, a blurring and/or a decimation operator associated with the image gi to generate a projected super-resolution enhanced image estimate. The super-resolution enhanced image estimate update generator module is configured to use the input image gi and the super-resolution enhanced image estimate to generate an updated super-resolution enhanced image estimate.
摘要:
A system and method for generating a mosaic image from respective regions in a plurality of individual images, at least one of the regions being distorted and having a left and/or right edge that is tilted relative to a direction of view of the respective image. The distorted regions are rectified so as to form a respective rectified rectangular region and at least some of the rectified rectangular regions are mosaiced to form the mosaic image.

A super-resolution-enhanced mosaic image generating system is provided for generating a super-resolution-enhanced mosaic image from a plurality of image frames, each image frame being associated with image data representative of an image of a portion of a scene. The mosaic image generating system comprises a mosaic image generator and a super-resolution generator. The mosaic image generator uses the image data from the image frames to generate mosaic image data representing a mosaic image. The super-resolution generator uses the mosaic image data and the image data from the image frames to generate the super-resolution-enhanced mosaic image. In that process, the super-resolution generator divides the mosaic image into a plurality of patches, each patch associated with at least one image frame, and performs a super-resolution operation in connection with the patch and image frames associated therewith to generate the super-resolution-enhanced mosaic image.

A system is described for generating a rectified mosaic image from a plurality of individual images, the system comprising a quadrangular region defining module, a warping module and a mosaicing module. The quadrangular region defining module is configured to define in one individual image a quadrangular region in relation to two points on a vertical anchor in the one individual image and mappings of two points on a vertical anchor in at least one other individual image into the one individual image. The warping module is configured to warp the quadrangular region to a rectangular region. The mosaicing module configured to mosaic the quadrangular region to the mosaic image. The system further generates a mosaic from a plurality of panoramic images, the system comprising a motion determining module, a normalizing module, a strip selection module, and a mosaicing module. The motion determining module is configured to determine image motion between two panoramic images. The normalizing module is configured to normalize respective columns in the panoramic images in relation to the ratio of the image motion thereof to the image motion of a selected column, thereby to generate normalized panoramic images. The strip selection module is configured to select strips of the normalized panoramic images. The mosaicing module is configured to mosaic the selected strips together.
摘要:
A computer-implemented method and system transforms a first sequence of video frames of a first dynamic scene to a second sequence of at least two video frames depicting a second dynamic scene. A subset of video frames in the first sequence is obtained that show movement of at least one object having a plurality of pixels located at respective x, y coordinates and portions from the subset are selected that show non-spatially overlapping appearances of the at least one object in the first dynamic scene. The portions are copied from at least three different input frames to at least two successive frames of the second sequence without changing the respective x, y coordinates of the pixels in the object and such that at least one of the frames of the second sequence contains at least two portions that appear at different frames in the first sequence.
摘要:
A computer-implemented method and system for transforming a first sequence of video frames of a first dynamic scene captured at regular time intervals to a second sequence of video frames depicting a second dynamic scene wherein for at least two successive frames of the second sequence, there are selected from at least three different frames of the first sequence portions that are spatially contiguous in the first dynamic scene and copied to a corresponding frame of the second sequence so as to maintain their spatial continuity in the first sequence. In a second aspect, for at least one feature in the first dynamic scene respective portions of the first sequence of video frames are sampled at a different rate than surrounding portions of the first sequence of video frames; and the sampled portions are copied to a corresponding frame of the second sequence.

A computer-implemented method and system determines camera movement of a new frame relative to a sequence of frames of images containing at least one dynamic object and for which relative camera movement is assumed. From changes in color values of sets of pixels in different frames of the sequence for which respective locations of all pixels in each set are adjusted so as to neutralize the effect of camera movement between the respective frames in the sequence containing the pixels, corresponding color values of the pixels in the new frame are predicted and used to determine camera movement as a relative movement of the new frame and the predicted frame. An embodiment of the invention maintains an aligned space-time volume of frames for which camera movement is neutralized and adds each new frame to the aligned space-time volume after neutralizing camera movement in the new frame.

Systems are disclosed for generating left and right panoramic mosaic images for use in facilitating panoramic stereoscopic viewing of a scene, and for displaying stereoscopic panoramic images to a viewer. The left and right panoramic image generators generate the left and right panoramic mosaic images from a series of images recorded or otherwise generated corresponding to respective angular or other positions, each image having a respective left and right image portion, and mosaics portions of those images together to form the respective left and right panoramic images. The display system displays a stereoscopic panoramic image to a viewer by displaying left and right panoramic images such that each is viewed by a respective one of the viewer's eyes.
