# goimagehash
|
|
> Inspired by [imagehash](https://github.com/JohannesBuchner/imagehash)
|
|
|
|
A image hashing library written in Go. ImageHash supports:
|
|
* [Average hashing](http://www.hackerfactor.com/blog/index.php?/archives/432-Looks-Like-It.html)
|
|
* [Difference hashing](http://www.hackerfactor.com/blog/index.php?/archives/529-Kind-of-Like-That.html)
|
|
* [Perception hashing](http://www.hackerfactor.com/blog/index.php?/archives/432-Looks-Like-It.html)
|
|
* Wavlet hashing [TODO]
|
|
|
|
**Only support 64bits hash.**
|
|

## Usage
|
|
|
|
``` Go
|
|
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)
|
|
}
|
|
```
