MATLAB: What is meant by slicing of an image

Image Processing Toolboximage slicing

In many papers, I have come across the word " slicing of an image" . Can you tell what exactly it do. Does it means dividing the input image

Best Answer

This usually means taking a plane out of a 3D volumetric image. For example, in a CT or MRI image, you can take a slice along the X, Y, or Z dimension, or even a plane at some arbitrary orientation. You get a 2D image of the pixel values that would lie on that plane.

A 1D image is just a line, like you extract a single line out of a 2D gray scale image. A 2D image can be a grayscale or color image in layman's parlance, though in MATLAB, a 2D color image is actually a 3D image because it has 3 2D images - one for each color plane. A 3D image can be a color image, like I just said, or it can be a hyper spectral image, like for satellite/remote sensing, where you have 7 or more wavelength bands that the sensor collected. A 3D image may also be a grayscale volumetric image, like from MRI or CT. So it's a mapping of what's inside a volume and gives the density, activity, temperature, brightness, concentration, or whatever you're measuring, at each x,y,z location in a 3D rectangular volume/box.

Is that what you meant by "interprate"?

MATLAB: Sliced variables

To slice the variable 'a', you need to use a subscript list that contains:

One instance of the loop variable
Other subscripts which are either constant literal values or ':'

So, for example, in the following case, 'a' will be a sliced output:

parfor n = 1:35
  tmp = 90 * ones(1, 15);
  a(n, :) = tmp;
end

which creates 'a' as a 35x15 matrix with each element containing the value 90.
