Android real time image processing using JavaCV
Показать описание
A little Android app i wrote to demonstrate real time image processing.
The android camera preview (YUV format) is converted to RGB color space (upper left image on tablet) and split into red (upper right), green (lower left) and blue (lower right) intensity images.
The gray-values (0..255) represent the red, green and blue amount of the original image.
This visualisation can help to distinguish between colors (e.g. for
people with red-green dyschromatopsia).
All calculations are done in real time at at least 15 frames per second.
App created with Basic4Android (B4A v3.80) , some funcions of JavaCV (OpenCV) were wrapped and used as a B4A library.
Device : Nexus 7 (2013) , Android 4.3 Jelly Bean, not rooted
Filmed with Panasonic Lumix FS 16
