Abstract:
1. A method for computerized analysis of particular color changes of specific clinical nature for all types of medical analysis pertaining to color, present in one image originating from at least one lesion in human body tissue, comprising: a) placing a matching reference label having a plurality of reference colors, in the vicinity of every analyzed lesion, said reference label having a window cut in it and placed so as to surround the corresponding lesion size and shape associated with an area of interest (AOI) therein; b) capturing a color image including every analyzed lesion and the corresponding reference label along with human tissue encompassing said reference label, wherein said image is a digital image or is converted into a digital image; c) performing color calibration of the image using the LAB color system, said calibration comprising reading the color intensity value of at least one reference color from the reference label in the image, comparing said value to the true predetermined color intensity value of said reference color, and optionally correcting the digital data of the image in at least one channel within the LAB color system, for color distortion; d) selecting the borders of said AOI within the image; c) calculating the intensity and distribution of color within said area of interest in relation to said reference label using at least one channel of the LAB system, to give at least one color information attribute within a clinically relevant range; and f) displaying said at least one color information attribute upon display means; wherein at least steps (c) and (e) are performed by a processing means allowing color calibration and allowing calculation and display of said at least one color information attribute.
