Input raster | The input raster whose values will be scaled from 0 to 1. It can be an integer or a floating-point raster. | Raster Layer |

Membership type (Optional) | Specifies the algorithm used in fuzzification of the input raster. Certain settings for Membership type employ a Spread parameter to determine how rapidly the fuzzy membership values decrease from 1 to 0. The default values for the spread are detailed in the table below. - Gaussian—Assigns a membership value of 1 at the midpoint.The membership decreases to 0 for values that deviate from the midpoint according to a normal curve. Gaussian is similar to the Near function but has a more narrow spread.
- Midpoint — Default is the midpoint of the range of values of the input raster.
- Spread — Default is 0.1. Typically, the values vary between [0.01–1].
- Small—Used to indicate that small values of the input raster have high membership in the fuzzy set.Assigns a membership value of 0.5 at the midpoint.
- Midpoint — Default is the midpoint of the range of values of the input raster.
- Spread — Default is 5.
- Large—Used to indicate that large values of the input raster have high membership in the fuzzy set.Assigns a membership value of 0.5 at the midpoint.
- Midpoint — Default is the midpoint of the range of values of the input raster.
- Spread — Default is 5.
- Near—Calculates memberships for values near some intermediate value.Assigns a membership value of 1 at the midpoint. The membership decreases to 0 for values that deviate from the midpoint.
- Midpoint — Default is the midpoint of the range of values of the input raster.
- Spread — Default is 0.1. Typically, the values vary within the range of [0.001–1].
- MSLarge—Calculates membership based on the mean and standard deviation of the input data where large values have high membership. The result can be similar to the Large function, depending on how the multipliers of the mean and standard deviation are defined.
- Mean multiplier — Default is 1.
- Standard deviation multiplier — Default is 2.
- MSSmall—Calculates membership based on the mean and standard deviation of the input data where small values have high membership. This is the default membership type. The result can be similar to the Small function, depending on how the multipliers of the mean and standard deviation are defined.
- Mean multiplier — Default is 1.
- Standard deviation multiplier — Default is 2.
- Linear—Calculates membership based on the linear transformation of the input raster. Assigns a membership value of 0 at the minimum and a membership of 1 at the maximum.
- Minimum — Default is 1.
- Maximum — Default is 2.

Hedge (Optional) | Defining a hedge increases or decreases the fuzzy membership values which modify the meaning of a fuzzy set. Hedges are useful to help in controlling the criteria or important attributes. - None—No hedge is applied. This is the default.
- Somewhat—Known as dilation, defined as the square root of the fuzzy membership function. This hedge increases the fuzzy membership functions.
- Very—Also known as concentration, defined as the fuzzy membership function squared. This hedge decreases the fuzzy membership functions.
