Cover Story: Both the human eye and a digital camera sense both light intensity and color. We use visual information for various purposes, including seeing things, keeping our physical balance, and making judgments based on one's situational experiences. It naturally becomes subjective and uncertain. The quantification of color from digital images, including prints and static/dynamic digital data, is necessary to reduce uncertainty and subjectivity for quantified data-driven judgments and control applications in various fields. This study shows reliable, image-based quantification of color using specially developed image processing and analysis software. This image-based quantification software (PicMan) is useful for a wide range of applications in art, fashion, medical science, and many other fields. View this paper
