Phasher ✅

So, around a week ago I was struggling to compare similarities between two images and found a way i.e Phash (perceptual hash) algorithm. It's based upon https://www.phash.org/.❤️

⌨️ Usage

1. Add dependency.

repositories {
  maven { url 'https://jitpack.io' } // Add jitpack
}

dependencies {
  implementation 'com.github.KapilYadav-dev:Phasher:Tag'
}

2. Use Phash() function.

1st way using file path.

fun Phash(
    fileOnePath: String?, // path of Image one 
    fileTwoPath: String?, // path of Image two
    bitSize: Int = 8  // This is the size you want to resize, can play with it for more accuracy and its best with the value 8
)

2nd way using file uri.

fun Phash(
    uriOne: Uri?, // Uri for Image one
    uriTwo: Uri?, // Uri for Image two
    context: Context
)

Finally use getSimilarityScore() method which will return % of confidence.

i.e.

val score = Phash(path1,path2).getSimilarityScore()
// score = 70 %
val scoreTwo = Phash(uri1,uri2,context).getSimilarityScore()
// score = 70%

Results

Image 1	Image 2

Result 89 % match ✅

Important Note ✍️

Choose your threasold for your image as per your usecase.
For a standard one, we use 75 % threasold that means above its image are similar.
