System and method for robust estimation of color dependent measurements

摘要

Methods, devices, and computer program products for robust estimation of color-dependent measurements are described herein. In one aspect, a method for generating a reference color grid that may be placed beside a color-dependent measuring device is disclosed. The reference color grid may contain a number of colors which enable a mapping from the color space of a testing device to a reference color space. This mapping may allow a function that is able to determine an estimate of a color-dependent measurement based on a color in the reference color space to be used. In another aspect, a method for robust estimation of color-dependent measurement using a reference color guide is disclosed.

主权项

1. A method running on a processor for using a color guide to estimate a color-dependent measurement, the method comprising:
receiving a learned function and a reference color guide; receiving an image, wherein the image comprises a color guide and a colored device configured for color-dependent measurement; mapping the received image of the color guide to the reference color guide; determining a location in a reference color space corresponding to the image of the colored device, the location based at least in part on the mapping of the received image of the color guide to the reference color guide; and determining an estimate of a color-dependent measurement, based at least in part on the location in the reference color space and on the learned function.
