Dynamic time warping for Javascript. As simple usecase would be
Touch signature identification with Javascript
for example.
Several quick start options are available:
* Download the latest release.
* Clone the repo: git clone https://github.com/GordonLesti/dynamic-time-warping.git.
* Install with npm: npm install dynamic-time-warping.
* Install with Bower: bower install dynamic-time-warping.
Include script (unless you are packaging scripts somehow else):
``html`
The plugin can also be loaded as AMD or Node module.
DynamicTimeWarping needs two arrays containing objects of the the same type and function that calculates the distance
between two objects and returns a float.
`javascript
var ser1 = [ 9, 93, 15, 19, 24 ];
var ser2 = [ 31, 97, 81, 82, 39 ];
var distFunc = function( a, b ) {
return Math.abs( a - b );
};
var dtw = new DynamicTimeWarping(ser1, ser2, distFunc);
`
Will return the distance of the dynamic time warping as float.
`javascript`
// 108
var dist = dtw.getDistance();
Will return the path of the dynamic time warping as array of arrays with two integers.
`javascript`
// [ [ 0, 0 ], [ 1, 1 ], [ 1, 2 ], [ 1, 3 ], [ 2, 4 ], [ 3, 4 ], [ 4, 4 ] ]
var dist = dtw.getPath();
