ndarray-convolve:ndarrays 的卷积和互相关

ndarray 卷积 上的和。 例子 //Read in test image var lena = require ( "luminance" ) ( require ( "lena" ) ) //Generate a 5-point Laplace filter var filter = require ( "ndarray-pack" ) ( [ [ 0 , 1 , 0 ] , [ 1 , - 4 , 1 ] , [ 0 , 1 , 0 ] ] ) //Convolve them together require ( "ndarray-convolve" ) ( lena , filter ) 这将产生以下数组： 安装 npm
