Go Perceptual image hashing package

goimagehash

Inspired by imagehash

A image hashing library written in Go. ImageHash supports:

• Average hashing
• Difference hashing
• Perception hashing
• Wavelet hashing [TODO]

Only support 64bits hash.

Installation

go get github.com/ilaripih/goimagehash

Usage

func main() {
        file1, _ := os.Open("sample1.jpg")
        file2, _ := os.Open("sample2.jpg")
        defer file1.Close()
        defer file2.Close()

        img1, _ := jpeg.Decode(file1)
        img2, _ := jpeg.Decode(file2)
        hash1, _ := goimagehash.AverageHash(img1, 8)
        hash2, _ := goimagehash.AverageHash(img2, 8)
        distance, _ := hash1.Distance(hash2)
        fmt.Printf("Distance between images: %v\n", distance)

        hash1, _ = goimagehash.DifferenceHash(img1, 8)
        hash2, _ = goimagehash.DifferenceHash(img2, 8)
        distance, _ = hash1.Distance(hash2)
        fmt.Printf("Distance between images: %v\n", distance)
