Color quantitation through image processing in dermatology

Abstract: Classical color models and their applications to computer vision are reviewed. The performances of color quantitation from digitized images are compared with those derived from a chromameter. The color quantitation obtained from either digitized color slides or directly digitized images is proved to be more efficient than the conventional visual assessment of observers. A methodology is proposed for determining the specific color indices which are needed in dermatology. An application of this methodology is de… Show more

“…Although we experimented with the inter-quartile range, retaining central tendencies, and the improvement in the accuracy of classification was not significant. [20] There are some limitations in the presented study. As reported, a modified HSI space was used, which involves a shift of the origin.…”

“…Specifically, suppose that a close approximation of f,f, can be exactly expressed as a linear combination of M basis functionsf = Fd (2) where F is an N M matrix whose columns contain the basis functions that describe most of the reflectance spectra in a training dataset, and d is the M-element vector which represents the weights of the linear expansion (2).…”

“…However, nowadays, the research in the field of color skin images is limited to two main applications [4]. They are the assessment of the healing of skin wounds or ulcers [5][6][7], and the diagnosis of pigmented skin lesions such as melanomas [8][9][10]. Nevertheless, this research is being developed slowly due to the difficulty of translating color human perception into objective rules, analyzable by a computer.…”
