摘要： Given an image with an unwanted feature, a collection of pixels (a defined region) entirely containing the unwanted feature is designated, and replacement data values for the defined region are generated, thereby healing the unwanted feature. A selected image region is healed by propagating values in a boundary region into replacement data values for the selected image region by iteratively applying a procedure or algorithm (e.g., iteratively applying one or more kernels), such that values in the boundary region are continuously put back into the iterative calculations. An example of such a function uses kernels to generate replacement data values having multiple orders of continuity at the boundary. Optionally, replacement data values for an image region to be healed are generated based on a difference between existing data values and texture data values, thereby introducing texture (e.g., pattern, noise) components to a resulting healed region in the image. Mutiresolution processing and tiling can also be used to enhance performance.

摘要： A system and method for expansion and reduction of images in an image editing application uses the frequency of pixels values (e.g., absolute color and/or intensity values) of an input image to determine respective energy values for each pixel of the image. The energy values may vary inversely with the frequency of the pixel values. The energy values may be used to determine one or more low-cost seams of the image to be removed for an image reduction operation or replicated for an image expansion operation, where the cost of each seam is dependent on the energy values of the pixels of the seam. Determining the frequency of pixel values of the image may involve determining the number of pixels having an absolute pixel value in each of a plurality of pixel value ranges, and the absolute pixel values included in each range may be configurable by the user.

摘要： Methods, apparatus, and computer-readable storage media for tone mapping High Dynamic Range (HDR) images. The HDR image is separated into luminance and color. Luminance is processed according to the parameters to obtain a base layer and a detail layer. The base layer is compressed into a lower dynamic range and the detail layer is adjusted according to the parameters. The compressed base layer, the detail layer, and the color component may be output as separate layers, and various image processing tools and techniques may be applied to the component layers separately to modify the layer(s). One or more tone-mapped images may be generated by merging the modified layers. Thus, each layer of the tone-mapped image may be processed separately using various image processing tools or techniques to modify the output of the tone mapping technique in a wide variety of ways.

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.
摘要翻译：用于操纵数字图像的方法和装置。描述了一种翘曲模块，其能够通过在保持局部刚性的同时选择性地使表面的部分变形来操纵表面。用户可以在表面上放置多个控制点以约束变形。用户可以在每个控制点处指定多个属性（例如，平移，旋转，深度和缩放）。网格可以覆盖在表面上。翘曲模块可以执行初始化，其中属性在网格中传播其他顶点以生成初始变形的网格。然后，翘曲模块可以对变形的网格进行迭代优化操作，以改善变形，同时保持局部刚度。因此，翘曲模块不是移动表面中的每个像素，而是移动或调整网格顶点的坐标。然后根据变形的网格使表面变形。
