# superpixels

2-D superpixel oversegmentation of images

## Description

`[`

computes superpixels of the 2-D grayscale or RGB image `L`

,`numLabels`

]
= superpixels(`A`

,`N`

)`A`

.
`N`

specifies the number of superpixels you want to create. The
function returns the label matrix `L`

and the actual number of
superpixels that were computed, `numLabels`

.

The `superpixels`

function uses the simple linear iterative clustering
(SLIC) algorithm [1]. This algorithm groups pixels into regions with similar values.
Using these regions in image processing operations, such as segmentation, can reduce the
complexity of these operations.

`[`

computes superpixels of image `L`

,`numLabels`

]
= superpixels(`A`

,`N`

,`Name=Value`

)`A`

using name-value arguments used to
control aspects of the segmentation.
