摘要: Some embodiments provide a computer program for performing a color matching operation. The computer program identifies first and second images. Each image includes several pixels. Each pixel includes a luma component value. Based on analysis of the luma component values of the pixels of the first and second images, the computer program determines a set of transforms to modify pixel values of the first image so that the pixel values of the first image are similar to pixel values of the second image. The computer program applies the set of transforms to the first image such that the pixel values of the first image are similar to the pixel values of the second image.

摘要: Some embodiments provide a computer program for matching colors of a first image to colors of a second image. The computer program identifies a set of transforms for converting the first image to a device-independent color space. The computer program modifies the set of transforms to segment colors of the first image into a set of segmented colors. The computer program applies the modified set of transforms to pixel values of the first image in order to segment the pixels of the first image into the set of segmented colors. The computer program applies the modified set of transforms to pixel values of the second image in order to segment the pixels of the second image into the set of segmented colors. The computer program matches each segmented color in the set of segmented colors in the first image to the segmented color in the second image.

摘要: Some embodiments provide a method for selecting a portion of an image. The method identifies edges in the image. The method defines a border about the portion of the image by using the identified edges. The method represents the border as a deformable curve. In some embodiments, defining the border includes detecting a cursor moving over the image and defining the border along identified edges in the vicinity of the cursor. In some embodiments, the method searches for edges in the vicinity of the cursor and snaps the border to the edges. Identifying the edges of the image includes performing an edge detection algorithm in some embodiments. Identifying the edges further includes performing a de-noise algorithm in some embodiments. In some embodiments, the parametrizable curve is a bezier spline.

摘要: Some embodiments provide a method of color correcting an image. Some such embodiments provide (1) a display area for displaying a modifiable graph correlating a first color attribute of the image to a set of second color attributes and (2) at least one tool that adjusts the graph in order to adjust color attributes in the image. The graph adjustment tool of some embodiments is a set of control points that specify the color correction adjustment over a parameterized curve representation of the graph. In some embodiments, the graphs are rasterized curves that are adjusted through the use of a Gaussian manipulator. The Gaussian manipulator distributes a second color attribute adjustment over a set of first color attribute values according to a Gaussian distribution. Moreover, some embodiments allow for the selective switching between the parameterized and rasterized curves or the control points and the Gaussian manipulator.

摘要: Some embodiments provide a method for automatically selecting a portion of an image that includes several pixels, each of which has a set of pixel values. The method identifies a background color of the image. For each region of a set of regions of a color space that correspond to the background color, the method determines whether a threshold number of pixels in the image have pixel values that are in the region. The method identifies the pixels of the image in the regions that correspond to the background color and have a threshold number of pixels in the image. The method generates a portion of the color space to define a selection of the image using the pixel values of the identified pixels.
