How to calculate net absorbance
Web2 aug. 2024 · Anne Marie Helmenstine, Ph.D. Updated on August 02, 2024. Absorbance is a measure of the quantity of light absorbed by a sample. It is also known as optical density, extinction, or decadic absorbance. The property is measured using spectroscopy, particularly for quantitative analysis. Typical units of absorbance are called … Web13 jan. 2024 · Is it possible to calculate those? I had success in calculating the mean pixel intensity using. meanGrayscale = 0.2989 * r.mean() + 0.587 * g.mean() + 0.114 * b.mean() Transforming an image and then calculating the grayscale mean, gives the same result as first calculating the RGB means and then transforming those to a grayscale mean.
