Abstract: 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.

Abstract: An application that receives and edits image data from a light field camera. The application determines a distance from the light field camera for each portion of the image. The application of some embodiments uses the depth information to break the image data down into layers based on the depths of the objects in the image. In some embodiments, the layers are determined based on a histogram that plots the fraction of an image at a particular depth against the depths of the image.

Abstract: 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.

Abstract: Some embodiments provide a method that provides a display area for displaying an image that includes several of edges. The method provides a border drawing tool that in response to cursor movement across the image displays a search window about the cursor. The search window specifies a region to be searched to identify edges for use in defining a border for the image. In some embodiments, the size of the search window varies based on the speed of the cursor. The search window is a square box in some embodiments and a circle in other embodiments. The search window is centered at the cursor in some embodiments. In some embodiments, the display area is also for displaying the defined border over the image.

Abstract: A computing device harmonizes output image properties displayed on a graphical user interface (GUI) when a user switches between two or more images of different image formats to display on the GUI. When a user interacts with a user interface to change one or more display properties of an image, a system modifies displayed image properties based on the user's modifications. If the user selects another image with different dynamic range than the first image, the system performs a backend image conversion so that the displayed properties of the second image correspond to the user-selected modifications to the displayed properties of the first image.

Abstract: A method that generates a chromakey image and then generates a color corrected, spill suppressed chromakey image. The application identifies the edges of non-transparent objects in the image and determines whether the edges are dark. If the edges are dark, then the application subtracts the color corrected, spill suppressed chromakey image from the chromakey image. The subtraction generates an outline image that includes a bright outline of the objects with the dark edges, while the objects themselves in the outline image are almost entirely black. The application then darkens, based on the outline image, the pixels of the color corrected, spill suppressed chromakey image.
