    摘要: A method, system, and computer-readable storage medium are disclosed for generating a location-weighted mask based on a color model comprising spatial dimensions. In one embodiment, a selection of at least one pixel in an input image is received, wherein the selection of the at least one pixel comprises a color and a location within the input image. A color model may be determined based on the color and the location of the at least one pixel, wherein the color model comprises one or more truncated Gaussian functions. A mask may be generated based on the color model. The mask may indicate a degree of membership in the mask for each pixel in the input image as a function of a similarity in color to the at least one pixel in the selection and a proximity to the location of the at least one pixel in the selection.

    摘要: A system and method for expansion and reduction of images uses variable seam replication to expand an image. Seam carving techniques may be used to identify one or more low-cost seams of an input image, and these low-cost seams may be replicated to produce a resized version of the image. A different replication factor may be applied to different ones of the low-cost seams, dependent on the average or total energy value of each seam. For example, the lowest cost seam may be replicated twice as many times as the next lowest cost seam. The replication factor applied to each seam may be dependent on the number of low-cost seams identified for replication, which may be configurable by users. A configurable look-up table may map seam costs to replication factors, and may be accessed to determine a respective replication factor to be applied to each of the identified low-cost seams.

    摘要: Methods and apparatus for matching image metadata to a profile database to determine image processing parameters are described. In embodiments, image metadata may be used to match input images against a profile database. For example, camera make and model information and/or lens make and model information may be retrieved from the image metadata corresponding to an input image and used to locate a best match profile in the profile database. Additional custom data may then be retrieved from the located profile to perform processing that may be optimized for a specific camera and lens that captured the images, and in some cases for particular camera settings. The profile database may be generated via a calibration process applied to each of a plurality of camera/lens combinations. In one embodiment, the additional custom data may be adjusted or scaled to account for differences in cameras, lenses, or settings.

    摘要: A system and method for expansion and reduction of images uses an absolute value associated with each pixel of an input image (e.g., a color and/or intensity value) to determine a respective energy value for each pixel. For example, a given color or range of colors (e.g., skin tones, or other high-priority colors) may be assigned higher energy values than other colors and/or color ranges, and may be protected during image reduction and/or expansion. These energy values may be used to determine a cost associated with various seams of the image, which may represent the priority of the seams in the image. One or more low-cost seams may be identified for removal or replication to produce a resized image. The methods may be used in conjunction with an automated skin tone detector or a user interface that allows selection of one or more high priority colors or color ranges.

    摘要: Methods and apparatus for manipulating digital images. A warping module is described that enables the manipulation of a surface by selectively deforming portions of the surface while maintaining local rigidity. The user may position multiple control points on a surface to constrain deformation. The user may specify multiple properties (e.g., translation, rotation, depth, and scale) at each control point. A mesh may be overlaid on the surface. The warping module may perform an initialization in which the properties are propagated other vertices in the mesh to generate an initial deformed mesh. The warping module may then perform an iterative optimization operation on the deformed mesh to improve the deformation while retaining local rigidity. Thus, instead of moving every pixel in the surface, the warping module moves or adjusts coordinates of the vertices of the mesh. The surface is then deformed according to the deformed mesh.
