AVL.ProfileDistance(AvlNet.Profile, AvlNet.Profile, AvlNet.DistanceMeasure, float)
Computes the [mean] square error between two profiles.
| Namespace: | AvlNet |
|---|---|
| Assembly: | AVL.NET.dll |
Syntax
public static void ProfileDistance( AvlNet.Profile inProfile1, AvlNet.Profile inProfile2, AvlNet.DistanceMeasure inDistanceMeasure, out float outDistance )
Parameters
- inProfile1
- Type: AvlNet.Profile
First input profile - inProfile2
- Type: AvlNet.Profile
Second input profile - inDistanceMeasure
- Type: AvlNet.DistanceMeasure
Measure of distance - outDistance
- Type: System.Single
Output distance value
Description
The operation computes the approximate difference between two profiles using the selected distance measure.
- If the inDistanceMeasure is set to MeanError then the resulting outDistance is the average difference between corresponding values of the profiles.
- If the inDistanceMeasure is set to MeanSquaredError then the resulting outDistance is the average squared difference between corresponding values of the profiles.
The operation requires that the profiles being compared have equal sizes, otherwise an error with appropriate description occurs.
Examples
![]() |
![]() |
Mean Squared Error between the sample profiles equals 25245.070.
![]() |
![]() |
Mean Error between the sample profiles equals 0.803.
Errors
| Error type | Description |
|---|---|
| DomainError | Sizes of input profiles differ in ProfileDistance. |
| DomainError | Empty profiles on input in ProfileDistance. |
| DomainError | DistanceMeasure type not supported in ProfileDistance. |
