Giới thiệu về OpenCV Demo 2

Enjoy millions of the latest Android apps, games, music, movies, TV, books, magazines & more. Anytime, anywhere, across your devices.

A demo app, based partly on the samples provided with the OpenCV library (Java wrapper version, v2.4.4). Demonstrates the use of Canny edge detection, Hough lines, Hough circles, 'in-range' colour detection, separate channel view, face detection, good-features-to-track and optical flow.

This app replaces the earlier version which has now been removed from play.google.

Larger screens (eg tablets) may be slow due to the amount of data being processed.

Read more about the app at http://www.barrythomas.co.uk/machinevision.html - Source code of the key sections of the frame processing loop are on the web site.

The app was written mainly as a learning exercise and is provided with no guarantee of road worthiness or fitness for purpose. Let me know if you want a copy of the source code.
