Function Documentation

function imgOut = mib_resize3d	(		img,
			scale,
			options
	)

Resize 3D dataset.

Resizing algorithms

• imresize - [default] (fastest) use imresize to resize XY dimension after resize the Z-dimension, gives somewhat softer images than other methods;
• interpn - interpolation for 1-D, 2-D, 3-D, and N-D gridded data in ndgrid format, quite fast but requires more memory that other methods
• tformarray - resize using a spatial transformation to N-D array, quite slow but more memory friendly comparing to interpn

Parameters

img	a 3D (y,x,z) or 4D (y,x,c,z) dataset for resize
scale	a number or a vector [scaleY, scaleX, scaleZ] for each dimension with resizing scaling factor, could be empty when options.width, options.height, options.depth fields are used
options	[optional], additional options .algorithm - a string with resizing algorithm: imresize, interpn, tformarray, see below for notes .width - a new width value, overrides the scale parameter .height - a new height value, overrides the scale parameter .depth - a new depth value, overrides the scale parameter .method - interpolation method, specified as a string that identifies a general method or a named interpolation kernel: imresize: nearest, bilinear, bicubic, box, triangle, cubic, lanczos2, lanczos3; interpn: linear, nearest, pchip, cubic, spline; tformarray - nearest, linear,cubic .imgType - a string with type of the dataset 4D or 3D .showWaitbar -> [optional], when 1-default, show the wait bar, when 0 - do not show the waitbar

Return values
