摘要： An “Oblique Image Stitcher” provides a technique for constructing a photorealistic oblique view from a set of input images representing a series of partially overlapping views of a scene. The Oblique Image Stitcher first projects each input image onto a geometric proxy of the scene and renders the images from a desired viewpoint. Once the images have been projected onto the geometric proxy, the rendered images are evaluated to identify optimum seams along which the various images are to be blended. Once the optimum seams are selected, the images are remapped relative to those seams by leaving the mapping unchanged at the seams and interpolating a smooth mapping between the seams. The remapped images are then composited to construct the final mosaiced oblique view of the scene. The result is a mosaic image constructed by warping the input images in a photorealistic manner which agrees at seams between images.

摘要： A gigapixel image is generated from a set of images in raw format depicting different portions of a panoramic scene that has up to a full spherical field of view. Radiometric alignment of the images creates a set of images in radiance format. Geometric alignment of the radiance format images creates a set of true poses for the images in radiance format. A gigapixel image depicting the entire scene is assembled from the set of radiance format images and radiance format true poses for the images. The set of images in raw format is captured using a conventional digital camera, equipped with a telephoto lens, attached to a motorized head. The head is programmed to pan and tilt the camera in prescribed increments to individually capture the images at a plurality of exposures and with a prescribed overlap between images depicting adjacent portions of the scene.

摘要： A dynamic tone mapping technique is presented that produces a local tone map for a sub-image of a wide-angle, high dynamic range (HDR), which is used in rendering the sub-image for display. The technique generally involves first computing a global tone map of the wide-angle, HDR image in advance of rendering the sub-image. The global tone map is then used during rendering to compute a local tone map based on the average luminance and contrast of the pixels of the sub-image. In addition, the sub-image can be tone mapped as part of the rendering of a sequence of sub-images during a viewer-executed panning and/or zooming session. In this case, the local tone maps can be kept from changing too rapidly by adding a hysteresis feature to smooth out the intensity changes between successive sub-images.
摘要翻译：提出了一种动态色调映射技术，它为广角，高动态范围（HDR）的子图像产生局部色调图，用于渲染子图像进行显示。该技术通常涉及首先在渲染子图像之前计算广角HDR图像的全局色调图。然后在渲染期间使用全局色调图，以基于子图像的像素的平均亮度和对比度来计算局部色调图。此外，子图像可以在观看者执行的平移和/或缩放会话期间作为一系列子图像的呈现的一部分进行色调映射。在这种情况下，通过添加滞后特征来平滑连续子图像之间的强度变化，可以保持局部色调图不会太快地改变。

摘要： A dynamic wide angle image viewing technique is presented which provides a way to view a wide-angle image while zooming between a wide angle view and a narrower angle view that employs both perspective and non-perspective projection models. In general, this involves first establishing the field of view for a view of the wide angle image that is to be displayed. The view is then rendered and displayed based on the established field of view, such that the projection transitions between a perspective projection associated with narrower angle views and a non-perspective projection (e.g., cylindrical, spherical or some other parameterization) associated with wider-angle views.
摘要翻译：提出了一种动态广角图像观看技术，其提供了在广角视角和使用透视投影模型和非透视投影模型的较窄角度视图之间进行放大时观看广角图像的方式。通常，这涉及首先建立要显示的广角图像的视图。然后基于所建立的视野来呈现和显示视图，使得投影在与较窄角度视图相关联的透视投影与与更宽角度视图相关联的非透视投影（例如，圆柱形，球形或某些其它参数化）角度视图。

摘要： The claimed subject matter can provide an architecture that facilitates producing a single image that can visualize a scene too large to depict from any single perspective view. These images can be stitched together on a 2-dimensional picture surface to form a multi-perspective image of the entire extent of the scene depicted by the input images. Where the respective images overlap, an objective function can be employed to determine where to make a transition between one image and the next. The objective function can employ a data cost and a seam cost to make this determination.

摘要： A system and method for improving digital flash photographs. The present invention is a technique that significantly improves low-light imaging by giving the end-user all the advantages of flash photography without producing the jarring look. The invention uses an image pair—one taken with flash the other without—to remove noise from the ambient image, sharpen the ambient image using detail from the flash image, correct for color, and remove red-eye.
