Abstract
Generating color vector previews for images is described. A color vector preview system processes image data using parallel pipelines: one for determining a color palette based on an image frame's depicted content and another for recoloring image frames using the color palette. The color vector preview system replaces each pixel of an image frame with a color determined from a surrounding spatial neighborhood of pixels. Input specifying a number of colors is received, and the specified number of colors are selected from replaced pixel values to define the color palette. After determining the color palette, the color palette pipeline obtains a most-recently captured image frame and updates the color palette accordingly. Simultaneously, the recoloring pipeline compares each of the replaced pixel values to the color palette and replaces each pixel based on the comparison. Recolored frames are then output as color vector previews for the image data in real-time.
