A repository of minified HAAR and LBP cascades. The performance is identical to OpenCV cascades but the file sizes are way smaller.

mallick_cascades

This repository contains minified versions of all OpenCV Haar and LBP cascades. Minification has been achieved by removing unnecessary white spaces and unnecessary precision. Some examples are shown below

Cascade Name File size Minified file size
haarcascade_eye.xml 336K 180K
haarcascade_frontalface_default.xml 912K 488K
haarcascade_frontalface_alt_tree.xml 2.6M 1.4M
lbpcascade_frontalface.xml 52K 36K

The original cascades are also shared for reference. The minified cascades are named with a prefix mallick_

Tester

I have added a tester script (tester.py) that loads a haar cascade and its minified version and displays the results on the same frame of the your webcam. The blue box denotes output of the haar cascade and the red box denotes the output of the minified cascade. The blue box is deliberately made 4 pixels smaller in width and height for display purposes. Here is the usage

python tester.py haarcascades/haarcascade_frontalface.xml
