Systems and methods for sensor-independent illuminant determination are provided. In one embodiment of the method, the method includes receiving one or more training images in raw-RGB format; generating an input histogram from each of the inputted raw images; generating a learned mapping matrix that map raw images to a learned mapping space by passing the one or more input histograms to a trained first machine learning model; generating one or more mapped images by applying the learned mapping matrix to the one or more training images; generating a mapped histogram from each of the mapped images; and determining the result illuminant by passing the one or more mapped histograms as input into a second machine learning model. A final illuminant for an input image can be determined by applying the result illuminant to the input color space of the input image.

Systems and methods for sensor-independent illuminant determination

Techniques are described for white balancing an input image by determining a color transformation for the input image based on color transformations that have been computed for training images whose color characteristics are similar to those of the input image. Techniques are also described for generating a training dataset comprising color information for a plurality of training images and color transformation information for the plurality of training images. The color information in the training dataset is searched to identify a subset of training images that are most similar in color to the input image. The color transformation for the input image is then computed by combining color transformation information for the identified training images. The contribution of the color transformation information for any given training image to the combination can be weighted based on the degree of color similarity between the input image and the training image.

Image white balancing

A system for analyzing and processing user input and providing a result based on a predetermined set of color identifiers, the system comprising a first user input, wherein the first user input comprises of one or more digital images, a second user input, wherein the second user input comprises of responses to queries, a white balancing method for removing color casts from the first user input to create a final corrected image of the first user input, a first database for storing a predetermined set of color identifiers, a second database for storing product profiles, and a processor for analyzing the final corrected image of the first user input and the second user input collectively, comparing the final corrected image of the first user input and the second user input collectively to the predetermined set of color identifiers, and providing a color output.
