[Pkg-phototools-devel] Bug#856593: facedetect: if facedetect is installed without recommends there is a missing depends to opencv-data

[Johan Haggi]

Package: facedetect
Version: 0.1-1
Severity: important

I install facedetect without recomends:

facedetect    Depends    libopencv-dev
libopencv-dev Recommends opencv-data
(installed libopencv-dev, not installed opencv-data)

after I test it with fgallery:

$ fgallery -i -v -f test.fgall www.fgal bla
[...]
+ facedetect --best --center www.fgal/imgs/NKN_0767_v0_02.jpg
facedetect: error: cannot load HAAR_FRONTALFACE_ALT2 from
/usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml
error: command "facedetect --best --center
www.fgal/imgs/NKN_0767_v0_02.jpg" failed

$ apt-file search haarcascade_frontalface_alt2.xml
digikam-data: /usr/share/digikam/facesengine/haarcascade_frontalface_alt2.xml
freemedforms-common-resources: /usr/share/freemedforms/textfiles/haarcascade_frontalface_alt2.xml
libkf5kface-data: /usr/share/libkface/haarcascades/haarcascade_frontalface_alt2.xml
opencv-data: /usr/share/opencv/haarcascades/haarcascade_frontalface_alt2.xml

# aptitude -R install opencv-data

now facedetect is OK
