Creates a profile with all its elements set to the same value.

Gets a single value from a profile, interpolated at any point.

Returns an array of all X and Y coordinates of the input profile.

Sets a single element in a profile, located at the specified index.

If the input profile contains at least one element, then it is copied to the output; otherwise Nil is returned.

Secures against domain errors caused by empty profiles, e.g. just before the ProfileAverage filter is to be invoked.

Adds two profiles value by value.

Adds profiles appearing in consecutive iterations value by value.

Divides two profiles value by value.

Computes the maximum of two profiles point by point.

Computes the maximum of profiles appearing in consecutive iterations.

Computes the minimum of profiles of an array.

Multiplies two profiles value by value.

Multiplies profiles appearing in consecutive iterations value by value.

Computes the average value of a profile.

Finds the locations at which the values of the input profile are locally highest or lowest.

Finds the lowest value of the input profile, its precise location and the corresponding index.

Finds subprofiles whose values fall into the specified range.

It may also be considered profile thresholding.

Finds pairs of opposite (raising and falling) edges in the input profile.

Can be used for 1D stripe detection when the brightness profile is extracted from an image in a non-standard way.

Finds the points of a profile at which the profile intersects the x-axis.

Serializes a profile to an AVDATA file.

Computes the derivative of a profile.

Changes a profile by choosing maximum point within a kernel.

Sharpens a profile using a 3x1 filter.

Smooths a profile by averaging points with one of ten pre-computed Gauss kernels.

Noise removal. Faster, but less accurate.

Computes the correlation between neighboring sub-profiles of different sizes and infers the most probable period length.

Computes the [mean] square error between two profiles.

Adds a scalar value to each element of a profile.

Divides each element of a profile by a scalar value.

Transforms each profile value to its negation.

Applies a linear transformation to a profile.

Checks whether values in the first profile are greater or equal than corresponding values in the second profile.

Confines a profile to its continuous subsequence.

Moves the last element ahead of the first one (inShift times).

Extends the profile by adding zeros at the beginning and at the end.

Undoes CropProfile.
