The value0corresponds to the absence of the component, while the value1corresponds to full saturation...
Each component can take any value between 0 (black) and 1 (white). For example, if each component takes a value between 0 and 1, the total range of possible colors is 0 to 255. When these three numbers are added together, the resulting number represents the light's intensity. ...
L*Luminance or brightness of the image. Values are in the range [0, 100], where 0 specifies black and 100 specifies white. AsL*increases, colors become brighter. a*Amount of red or green tones in the image. A large positivea*value corresponds to red/magenta. A large negativea*value co...
To initiate the spectral analysis process, the spectrometer undergoes a preheating phase aimed at achieving a consistent light irradiation. Subsequent to this step, a black and white correction procedure was executed. The initial stage of this correction process involves utilizing a whiteboard as the ...
