摘要： Many computing services incorporate large mosaics of geo-located images. For example, a user may access and interact with a digital image map comprising thousands of digital images mosaiced together. It may be advantageous to parallelize mosaic creation by splitting the mosaic into tiles, and processing the tiles independently from one another. Unfortunately, visual artifacts between image boundaries may result because of the independent processing. Accordingly, one or more systems and/or techniques for generating a substantially seamless mosaic tile are disclosed herein. A mosaic tile comprising one or more intersecting images may be received. Pair-wise image segmentation may be executed upon pairs of intersecting images within the mosaic tile to generate seam lines between the pair of intersecting images. The seam lines are used to compose the mosaic tile. A constrained alpha-expansion algorithm is executed upon hole regions within the composed mosaic to generate a substantially seamless mosaic.

摘要： Among other things, one or more techniques and/or systems are provided for quantifying blur of an image. Blur may result due to motion of a camera while the image is captured. Accordingly, motion measurement data corresponding to motion of the camera during an exposure event may be used to create a camera rotation matrix. A camera intrinsic matrix may be obtained based upon a focal length and principle point of the camera. A transformation matrix may be estimated based upon the camera rotation matrix and/or the camera intrinsic matrix. The transformation matrix may be applied to pixels within the image to determine a blur metric for the image. In this way, blur of an image may be quantified offline and/or in real-time during operation of the camera (e.g., so that the image may be re-acquired (e.g., on the fly) if the image is regarded as being overly blurry).

摘要： A surface model may be created from aerial photographs, while mitigating the staircase effect, by interpolating sub-pixel values in the photographs and using those sub-pixel values to calculate the offset between overlapping photographs. Aerial photographs are taken, which include overlapping regions. For a pair of photographs, the photographs are rectified to create coordinate systems in which the photographs have x-axes that coincide and y-axes that are parallel to each other, so that overlapping regions in one photograph are a fixed offset along the x-axis from the other photograph. Analytic functions are used to interpolate values between pixels, and the offset distance is calculated by finding the offset that maximizes a similarity function over the analytically interpolated values. The calculated offset may then be used to calculate the height of a point on the photographed surface. A surface model may be built by calculating the heights of many points.

摘要： When photographs are to be combined into a single image, haze correction and/or color balancing may be performed. The photographs may be analyzed and left-clipped in order to darken the photographs and to increase the density of pixels in the low-luminosity region, thereby decreasing the perception of haze. When the photographs are combined into one continuous image, tie points are selected that lie in regions where the photographs overlap. The tie points may be selected based on visual similarity of the photographs in the region around the tie point, using a variety of algorithms. Functions are then chosen to generate saturation and luminosity values that minimize, at the tie points, the cost of using the generated values as opposed to the actual saturation and luminosity values. These functions are then used to generate saturation and luminosity values for the full image.
