What is RGB in ImageJ?
24-bit RGB images The colors in RGB images (24-bit with 8-bits for each of the red, green and blue channels) are used to show multi-channel images. The colors are designed to reflect genuine colors (i.e. the green in an RGB image reflects green color in the specimen). There are several RGB functions in Fiji.
How does ImageJ calculate RGB values?
RGB Measure. Installation: Download RGB_Measure. java to the plugins folder, compile it using Plugins/Compile and Run, and there will be a new “RGB Measure” command in the Plugins menu the next time you restart ImageJ.
How do I convert an image from RGB to grayscale in ImageJ?
RGB images are converted to grayscale using the formula gray=(red+green+blue)/3 or gray=0.299red+0.587green+0.114blue if “Weighted RGB to Grayscale Conversion” is checked in Edit>Options>Conversions.
What is an RGB image?
An RGB (red, green, blue) image is a three-dimensional byte array that explicitly stores a color value for each pixel. RGB image arrays are made up of width, height, and three channels of color information. Scanned photographs are commonly stored as RGB images.
Which color model is best for monitors and other digital screens?
Both RGB and CMYK are modes for mixing color in graphic design. As a quick reference, the RGB color mode is best for digital work, while CMYK is used for print products.

What does “14Mb” mean in ImageJ?
It is a composite of three 8-bit grayscale images, one for red, one for green and one for blue. Images can also be 8-, 12-, 16- or 32-bit grayscale. Note: if you have a 12-bit grayscale image, ImageJ will list it as a 16-bit grayscale image. I do not know why this happens. 6) “14MB” is the amount of memory your image takes up on your hard drive.
How does ImageJ deal with color?
ImageJ deals with color mainly in three ways: pseudocolor images, RGB images, RGB/ HS B [?] stacks, and composite images. A pseudocolor (or indexed color) image is a single channel gray image (8, 16 or 32-bit) that has color assigned to it via a lookup table or LUT [?].
