Downsample by a factor of two using sinc interpolation
Downsamples an ndarray by a factor of 2 using sinc interpolation.
Here is a simple example showing how to downsample an image:
var lena =var x = 256256x lena 0 255x "png"
And here is the result:
npm install ndarray-downsample2x
Downsamples input by a factor of two storing the result in output.
outputgets the result of downsampling
inputis the array that gets downsampled
clamp_lois a threshold placed on the pixeks
clamp_hiis an upper threhsold placed on the pixels
input's shape must be divisible by 4 and
output's shape must be one half of
input's along each dimension.
