See :Category:Visualization for pages about scientific visualization.
Scientific visualization is a set of techniques for graphically illustrating scientific data, enabling scientists to better understand, illustrate, and glean insight from their data.
Getting Started with Simple Visualization Options in ImageJ
Pseudocolor Image Look-Up Tables (LUTs)
A pseudocolor image is a single channel gray image (8, 16 or 32-bit) that has color assigned to it via a lookup table, i.e. a LUT. A LUT is a predefined table of gray values with matching red, green, and blue values so that shadows of gray are displayed as colorized pixels. Thus, differences in color in the pseudo-colored image reflect differences in intensity of the object rather than differences in color of the specimen that has been imaged.
The LUT Menu of ImageJ contains a large collection of lookup tables that can be applied to a pseudocolor image.
Note: in the ImageJ 1.x user interface, LUTs are always 8-bit. When working with an image of higher bit depth, its intensity values are binned into 256 levels between minimum and maximum (see section Brightness/Contrast), and the LUT is applied onto these binned levels.
More information on this topic can be found on the Color Image Processing page.
Fluorescence images are usually acquired without color information (i.e. by monochrome cameras or with photomultipliers): each channel contains just intensity values. To display a multi-channel fluorescence image in composite mode (i.e. an overlay of all channels), each channel can be assigned a monochrome false-color LUT, e.g. ‘Red’, ‘Green’, ‘Blue’, ‘Cyan’, ‘Magenta’, ‘Yellow’, etc.
When analyzing quantitative data in an image, a false-color LUT (in this case also referred to as color map) can increase the visibility of low-contrasted features in the image and help the human eye to compare different images.
Here’s a list of recommended options to choose a LUT:
Quantitative display of positive values on a continuous scale
Assessment of over-/under-exposure in an image
