Find corresponding points between images. Using [OpenCV](https://opencv.org/) and [TensorFlow.js](https://www.tensorflow.org/js).

## Install

```bash

npm install linkimage

```

or

```bash

yarn add linkimage

```

## Usage

```javascript

const fs = require('fs')

const { link, linkMat } = require('linkimage')

const { imdecode, imread } = require('opencv4nodejs')

const srcBuffer = fs.readFileSync('images/src.jpg')

const dstBuffer = fs.readFileSync('images/dst.jpg')

// Find point on the destination image which corresponds to the specific point on the source image.

// The source point is the center of the source image.

const point = link(srcBuffer, dstBuffer)

// You can also specify a source point:

// const point = link(srcBuffer, dstBuffer, [100, 100])

// You can also use 'linkMat' method to pass Mat objects directly.

const srcMat = imdecode(srcBuffer)

const dstMat = imdecode(dstBuffer)

// Or use imread instead

// const srcMat = imread('images/src.jpg')

// const dstMat = imread('images/dst.jpg')

const point2 = linkMat(srcMat, dstMat)

// Returns the cordinates of the corresponding point in format [x, y].

// If no point found, return [-1, -1].

console.log(point)

```
