Questions tagged [tracking.js]

The tracking.js library brings different computer vision algorithms and techniques into the browser environment. By using modern HTML5 specifications, it enable you to do real-time color tracking, face detection and much more with a lightweight core (~7 KB) and intuitive interface.

Some of the Utilities and features that it provides are:

-Feature Detection: Provides an implementation of Features from Accelerated Segment Test for features detection. In other words it finds corners on parts of the image. Its faster than many other well-known feature extraction methods.

-Feature Descriptor: Provides an implementation of Binary Robust Independent Elementary Features. It uses binary strings as an efficient feature point descriptor. As a result, Brief is very fast both to build and to match, perfect for the web.

-Convolution: Convolution filters are very useful generic filters for image processing. The basic idea is that you take the weighed sum of a rectangle of pixels from the source image and use that as the output value. Convolution filters can be used for blurring, sharpening, embossing, edge detection and a whole bunch of other things.

-Integral Image: A summed area table is a data structure and algorithm for quickly and efficiently generating the sum of values in a rectangular subset of a grid. In the image processing domain, it is also known as an integral image.

-Sobel: Computes the vertical and horizontal gradients of the image and combines the computed images to find edges in the image.

-Viola Jones: The Viola–Jones object detection framework is the first object detection framework to provide competitive object detection rates in real-time.

You can install this using:

bower install tracking.js
