blend-methods

Merge Two NIfTI or ANALYZE Volumes

Description

Two volumes of medical imaging data are merged together in the superior-inferior (or $z$) direction. One assumes that there is at least one slice that overlaps between the two volumes.

Usage

blendVolumes(x, y, seqX, seqY, method = "linear")

## S4 method for signature 'nifti,nifti'
blend(x, y, seqX, seqY, method = "linear")

## S4 method for signature 'anlz,anlz'
blend(x, y, seqX, seqY, method = "linear")

## S4 method for signature 'anlz,nifti'
blend(x, y, seqX, seqY, method = "linear")

## S4 method for signature 'nifti,anlz'
blend(x, y, seqX, seqY, method = "linear")

Arguments

`x, y`	are objects of class `nifti` or `anlz`.
`seqX, seqY`	are vectors that provide the $z$-coordinate values for the two imaging volumes.
`method`	is the type of weighing to use when combining information where there is an overlap (default = `"linear"`).

Value

A single volume that blends the voxel-wise information from x and y.

Methods

x = "nifti", y = "nifti": Merge x and y.
x = "anlz", y = "anlz": Merge x on y.
x = "nifti", y = "anlz": Merge x on y.
x = "anlz", y = "nifti": Merge x and y.
