Abstract
Processor implemented systems and methods for matching color and appearance of a target coating are provided herein. A system includes a storage device for storing instructions, and one or more data processors. The data processor(s) are configured to execute instructions to receive a target image of a target coating. The data processor(s) are also configured to apply a feature extraction analysis process that divides the target image into a plurality of target pixels for image analysis.
Claims20
A system for matching a target coating comprising:
- a storage device for storing instructions;
- one or more data processors configured to execute instructions to:
- receive a target image of the target coating, wherein the target image comprises target image data;
- apply a feature extraction analysis process to the target image data to determine a target image feature comprising extracting a target pixel feature from the target image data based on image entropy of the target pixel feature, wherein the feature extraction analysis process comprises dividing the target image into a plurality of target pixels, determining the target pixel feature for individual target pixels of the plurality of target pixels, determining a target pixel feature difference between the individual target pixels, and using the target pixel feature difference to determine the target image feature;
- and
- determine a calculated match sample image with the target image feature based upon substantially satisfying one or more pre-specified matching criteria.
A method of matching a target coating comprising:
- obtaining, by one or more data processors, a target image of the target coating, wherein the target coating is an effect pigment-based coating, and wherein the target image comprises target image data;
- applying, by one or more data processors, a feature extraction analysis process to the target image data, wherein the feature extraction analysis process comprises:
- dividing the target image into a plurality of target pixels;
- determining a target pixel feature for individual target pixels of the plurality of target pixels, wherein determining the target pixel feature comprises extracting the target pixel feature from the target image data based on image entropy of the target pixel feature;
- determining a target pixel feature difference between the individual target pixels;
- and
- determining a target image feature from the target pixel feature difference;
- and
- determining a calculated match sample image with the target image feature based upon substantially satisfying one or more pre-specified matching criteria.
