....entropy measure and the maximum observed error. This suggests that this might provide a useful means of estimating the worst case error of a particular estimate generated by the algorithm. 5 Related Work Many color constancy methods have been described in the literature: 17] 16] 11] 7] [12], 13] 4] 8] 1] 19] 15] 10] One class of algorithms described by Forsyth [11] and Finlayson [7] utilizes constraints about the distribution of the extreme colors in an image and a search procedure to determine the transformation which best satisfies the given constraints. Funt [13] ....
....which best satisfies the given constraints. Funt [13] uses a neural network which takes as input the image color histogram to estimate chromaticities. Recent work by Funt [15] has made use of bootstrapping techniques, as was used here, as a source of training data. Freeman and Brainard, in [12] and [4] also describe a probabilistic model and attempt to solve the more ambitious problem of recovering full surface reflectance spectra. The work presented here is most closely related to the work described by Finlayson [8] 10] and Sapiro [19] Both of the algorithms described in these ....

....response to the same scene under a known, canonical light. In a general context this problem has proven difficult to solve, so to make progress, restrictive assumptions are made. In particular, it is common to assume that the scene is flat [9, 13, 14] that the illumination is constant throughout [2, 3, 9, 10, 15], and that all reflectances are matte. Finlayson [8] has shown that if we focus on solving only for surface chromaticity and forego estimating surface lightness then the restriction to flat matte surfaces can be relaxed. However, the assumption that the chromaticity of the illumination does not ....

.... reflectances over the entire scene is gray (the gray world assumption) Gershon [19] assumes that the average scene reflectance matches that of another known color; Vrhel [47] assumes knowledge of the general covariance structure of the illuminant, given a small set of illuminants, and Freeman [16] assumes that the illumination and reflection in a scene follow known probability distributions. These methods are effective when the distribution of colors within the scene follows the assumed model or distribution. In outdoor scenes, the CIE daylight model [22] suggests that the gray world ....

....acquired image. This prediction error was also small. 1 Introduction To process data from digital color cameras, it is often necessary to know the spectral response properties of the camera s sensors. For example, many demosaicing [1] color correction [13] and illuminant estimation algorithms [4, 5] require this knowledge. In addition, the intrinsic color quality of an image depends on the spectral characteristics of the sensors [2, 7, 12, 14, 15] used. Thus an important component of characterizing a digital color camera is measuring its sensor spectral response functions. We describe ....
