Abstract: This disclosure relates to system and methods for segmenting a video in a higher order dimensional space. A video may be segmented by obtaining visual information defining an image of the video. The visual information may include pixels of the image and may be represented in a display space having a first dimensionality. A designation of a subset of the visual information represented in the display space as a part of an object portrayed in the image may be obtained. The visual information and the designation may be represented in the higher order dimensional space having a second dimensionality greater than the first dimensionality. An association of the visual information represented in the higher order dimensional space with the object may be obtained. The association may be correlated with the visual information represented in the display space. The correlation may define a location of the object in the image.

Abstract: As described herein, an electronic device with a display screen may simulate the color diffusion that occurs in a physical painting process. For instance, the user may perform one or more actions that simulate a brushstroke on the display screen such as swiping a touch-sensitive area or dragging a cursor across the screen. The electronic device then calculates a geodesic distance between a pixel inside a region defined by the brushstroke and a pixel located outside this region based on the physical distance between the two pixels and a weighting factor that varies depending on whether an image boundary is between the two pixels. Based on the geodesic distance, the electronic device uses a color diffusion relationship that defines the effect of the color of the brushstroke on the pixel and a time delay controlling when the color of the brushstroke reaches the pixel in order to simulate color diffusion.
