I am trying to understand how to run computation for image processing on Javascript using GPU.
I have two list of bytes, 24 millions bytes each, each images are 4_000 by 6_000 = 24_000_000.
I want to just compare image1 with image2 pixel by pixel.
I do with CPU like this:
This takes a few seconds on CPU.
But how to do it on GPU to make it faster? We could breakdown the list into chunks and do the comparison of each chunk on a GPU core.
I could not find an example code online

I do with CPU like this:
Mã:
let image1: number[] = [
// 24 millions bytes
]
let image2: number[] = [
// another 24 millions bytes
]
let difference = 0
for (let i = 0; i < image1.length; i ++){
if (image1[1] === image2[2]) continue
difference ++
}
console.log(`Diffence is ${(difference /image1.length).toFixed(2) }`)
This takes a few seconds on CPU.
