ball-morphology
===============
Mathematical morphology for ndarrays where the structuring element is a ball in some Lp metric.

Example

First, let's read an image:

``javascript
var morphology = require("ball-morphology")

require("get-pixels")("bwimage.png", function(err, data) {
var r = data.pick(-1, -1, 0)

// ... do stuff ...
})
`

Which gives us the following array:

We can dilate the image using the following command:

`javascript
morphology.dilate(r, 1)
`

Which produces the following result:

Similarly, we can also perform an erosion:

`javascript
morphology.erode(r, 1)
`

Giving the result:

For convenience, openings and closing are also implemented:

`javascript
morphology.open(r, 1)
morphology.close(r, 1)
`




Install

npm install ball-morphology



API

`javascript
var morphology = require("ball-morphology")
`

$3

Performs a binary morphological dilation with an Lp ball of a given radius

* array is a binary image (updated in place)
* radius is the radius of the ball in pixel units (may be fractional)
* p is an optional argument giving the exponent of the metric. (Default 2)

Returns array

$3

Performs a binary morphological erosion with an Lp ball of a given radius

* array is a binary image (updated in place)
* radius is the radius of the ball in pixel units (may be fractional)
* p is an optional argument giving the exponent of the metric. (Default 2)

Returns array

$3

Performs a binary morphological opening with an Lp ball of a given radius

* array is a binary image (updated in place)
* radius is the radius of the ball in pixel units (may be fractional)
* p is an optional argument giving the exponent of the metric. (Default 2)

Returns array

$3

Performs a binary morphological closing with an Lp ball of a given radius

* array is a binary image (updated in place)
* radius is the radius of the ball in pixel units (may be fractional)
* p is an optional argument giving the exponent of the metric. (Default 2)

Returns array`
