Package Exports

ndarray-resample

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ndarray-resample) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ndarray-resample

Resamples an ndarray by an arbitrary (rational) factor using a sinc kernel.

Example

Here is a simple example showing how to downsample an image:

var baboon = require("luminance")(require("baboon-image"))
var x = require("zeros")([256,256])
require("ndarray-resample")(x, baboon)
require("save-pixels")(x, "png").pipe(process.stdout)

Output

##Install Install using npm:

npm install ndarray-resample

API

`require("ndarray-resample")(output, input[, clamp_lo, clamp_hi])`

Resamples input by a factor of output.shape/input.shape, storing the result in output (this also means the factor can differ per dimension).

output gets the result of resampling
input is the array that gets resampled
clamp_lo is a threshold placed on the pixels
clamp_hi is an upper threhsold placed on the pixels

Note that the pixel at the "origin" in the output corresponds to the pixel at the origin in the input. Also, the boundary conditions are periodic (for now).
