Stretch data from circular image to square in binary matrix
1 | stretch(imagematrix, method = "radial")
|
imagematrix |
The matrix to be stretched. |
method |
Stretch algorithm. Four algorithms (radial, shirley, squircle, and elliptical) are available to stretch the image. The algorithms were adapted from Lambers 2016. |
A matrix of 0, 1 and NA representing white, black and transparent pixels, respectively.
