goimagehash
Inspired by imagehash
A image hashing library written in Go. ImageHash supports:
Only support 64bits hash.
Installation
go get github.com/corona10/goimagehash
Special thanks to
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)
hash2, _ := goimagehash.AverageHash(img2)
distance, _ := hash1.Distance(hash2)
fmt.Printf("Distance between images: %v\n", distance)
hash1, _ = goimagehash.DifferenceHash(img1)
hash2, _ = goimagehash.DifferenceHash(img2)
distance, _ = hash1.Distance(hash2)
fmt.Printf("Distance between images: %v\n", distance)
}
