## Installment

```bash
$ npm i nodecv --save-dev
```

## Usage

Image IO:

```javascript
nodecv.imread(imagePath, callback);
nodecv.imread(buffer, callback);
nodecv.imwrite(outputPath, mat);
```

Image Dissimilarity:

```javascript
nodecv.imageDissimilarity(mat, mat, callback);
```

Match:

```javascript
nodecv.matchTemplate(mat, mat, method, callback);
nodecv.findPairs(mat, mat, callback);
```

Mat properties:

```javascript
im.width();
im.height();
im.size();
im.ellipse(x, y, width, height);
im.rectangle(x, y, width, height, color, thickness);
```

Cascade detect:

``` javascript
const haarcascade = 'path/to/haarcascade.xml';
const cascade = new nodecv.CascadeClassifier(haarcascade);
cascade.detectMultiScale(mat, callback);
```
