ndarray-log-polar

Given a 2D ndarray, convert it from cartesian to log-polar coordinates.

Example

var baboon = require('luminance')(require('baboon-image'))
var ndarray = require('ndarray')
var toPolar = require('ndarray-log-polar')
var imshow = require('ndarray-imshow')

imshow(ndarray(new Float64Array(256*256), [256,256]), baboon, {colormap: 'grey'})

API

require('ndarray-log-polar')(polar, rect[, center])

Converts an image from Cartesian to polar coordinates.

• polar gets the resulting image in polar coordinates
• rect is the input cartesian coordinate image
• center is an optional center for the cartesian coordinate image

Returns An image in polar coordinates
