ndarray-homography

Applies a homography to an ndarray.

Example

var imshow = require('ndarray-imshow')
var baboon = require('baboon-image')
var luminance = require('luminance')
var applyHomography = require('ndarray-homography')
var scratch = require('ndarray-scratch')

var baboonGrey = luminance(
  scratch.zeros([baboon.shape[0], baboon.shape[1]]),
  baboon)

imshow(applyHomography(
  scratch.zeros(baboonGrey.shape),
  baboonGrey,
  [1, 0, 0,
   0, 1, 0,
   0, 0, 1]
))

Install

npm install ndarray-homography

API

require('ndarray-homography')(dest, src, M)

Applies a homography to an ndarray.

• dest is a destination image, which has the same size as the input image
• src is the input image
• M is a homography encoded as a flattened matrix in column major order (consistent with OpenGL's format)

Returns dest
