ndarray和ops如何在浏览器中引入并处理图片data

Question

function preprocess(imageData) { const { width, height, data } = imageData; const dataTensor = ndarray(new Float32Array(data), [width, height, 4]) const dataProcessedTensor = ndarray(new Float32Array(width * height * 3), [width, height, 3]) //从[0,255]转化到[0,1] ops.divseq(dataTensor, 255) //获取R数据 ops.assign(dataProcessedTensor.pick(null, null, 0), dataTensor.pick(null, null, 0)) //获取G数据 ops.assign(dataProcessedTensor.pick(null, null, 1), dataTensor.pick(null, null, 1)) //获取B数据 ops.assign(dataProcessedTensor.pick(null, null, 2), dataTensor.pick(null, null, 2)) const preprocessedData = dataProcessedTensor.data; console.log('via process'); return preprocessedData; } 找不到 ndarray 和 ops 请问我该如何引用 ？谢谢 谢谢

Answer 1

scijs/ndarray，用npm安装，然后通过browserify在浏览器使用。
