1. A system for matching a target coating comprising:
a storage device for storing information, wherein a sample database is stored on the storage device, and wherein the sample database comprises a sample coating formula and a sample image feature wherein at least one sample coating formula is linked to at least one sample image feature, wherein each of the at least one sample coating formulas include a list of components and component quantities for a sample coating, and wherein the at least one sample image feature has been measured from the sample coating;
wherein the at least one sample image feature comprises a spatial micro-color analysis, wherein the spatial micro color analysis comprises a value determined by a sample pixel feature difference between at least two sample pixels of one sample image, wherein the spatial micro-color analysis comprises one or more of a sparkle area of a black and white version of the sample image, a sparkle intensity of the black and white version of the sample image, a sparkle grade of the black and white image of the sample image, a sparkle color determination of the sample image, a sparkle clustering of the sample image, a sparkle color differences determination within the sample image, and a wavelet coefficient determination of the sample image at the sample pixel level, wherein the sample image is an image of the sample coating, and wherein the sample image comprises a plurality of sample pixels.
