ipare

Image Compare Toolkit

Support

Hash Compare

• Average  
• Difference  

Pixel Compare

• Part
• Block

Usage

Hash

import (
	"github.com/gotokatsuya/ipare"
	"github.com/gotokatsuya/ipare/util"
	"github.com/gotokatsuya/ipare/algorithm/hash"
)

hash := ipare.NewHash()
// Default is DifferenceHash.
// hash.Algorithm = hash.NewAverage()
img1, _ := util.Open(imgPath1)
img2, _ := util.Open(imgPath2)

const threshold = 5
if distance := hash.Compare(img1, img2); distance <= threshold {
    // similar image
} else {
    // not same image
}

Pixel

import (
	"github.com/gotokatsuya/ipare"
	"github.com/gotokatsuya/ipare/util"
	"github.com/gotokatsuya/ipare/algorithm/pixel"
)

pixel := ipare.NewPixel()
// Default is DifferenceHash.
// pixel.Algorithm = pixel.NewBlock()
img1, _ := util.Open(imgPath1)
img2, _ := util.Open(imgPath2)

const threshold = 10
if distance := pixel.Compare(img1, img2); distance <= threshold {
    // similar image
} else {
    // not same image
}
