Abstract:
A method for monitoring and/or controlling the deposition of pattern and/or overall material coatings comprising the steps of:(a) Illuminating a material coating with a radiation source to generate backscattered radiation;(b) Acquiring an input RGB image from said backscattered radiation;(c) Building a monochrome image from said input RGB image;(d) Generating an enhanced image from said monochrome image;(e) Generating a dilated image from said enhanced image;(f) Generating a lowpass image from said dilated image;(g) Generating a thresholded image from said lowpass image;(h) Generating an inverted image from said thresholded image;(i) Saving only coating voids in said inverted image;(j) Superimposing said coating voids on said monochrome image.
