Description

Since update 2.4.3 the cascade multi detection using haarcascade isn't working anymore.
I tried to implement it with 2.3.1 precompiled windows7 x64 libs and this works.
Changing everything towards the 2.4.3 creates still executes the algorithm, nevertheless no rectangles are found anymore.

Anyone can help me out?

Hello Steven,

Could you attach a code to reproduce it? I am especially curious about what parameter do you use for detectMultiScale.
In my code, CascadeClassifier.detectMultiScale is working fine with OpenCV 2.4.3.

Hello Steven, I've just tested actual version of OpenCV 2.4.3 from '2.4' branch and everything look OK.
Using cascade from data/haarcascades/haarcascade_frontalface_default.xml, lena.jpg and Takahiro Horikawa's code I found a face at (221, 209)
So could you attach the code causing problems to you?

ok, presumably, the function should work now. We have added test for it in 2.4 branch, which passes on every our machine.

If the fresh snapshot from 2.4 or the upcoming 2.4.4 will still not work for you, try to run opencv_test_objdetect on your machine.
