GO-IMHASH

Calculate perceptual image distance hash in Go.

Requirements

• ImageMagick convert command line utility

Example

package main

import (
	"fmt"
    "github.com/24HOURSMEDIA/go-imhash"
)

func main() {
    // show hashed values and calculate distance 
	hasher, _ := imhash.CreateService("tom64b")

    imgPath1 := "./image1.jpg"
    imgPath2 := "./image2.jpg"
   
    hash1, _ := hasher.HashFromPath(imgPath1)
    hash2, _ := hasher.HashFromPath(imgPath2)
    fmt.Println(hash1.String())
    fmt.Println(hash2.String())
    fmt.Println(hasher.Distance(hash1, hash2))
    
    // show the population counts
    fmt.Println(hash1.(tom64b_hasher.Hash).PopCount())

}
