Doesn't look and OpenCV question...
agree ? Anyway:
- DBMS is a way. SQLite works very good also
for large record count and it can
easily enclosed in your C++
application. Binary blob is
supported too but it's up to you to
store the images into the DB or use
img files.
- You could use cv::FileStorage but you
can't have DB like query funcs.
Some hard coded way (not really flexible)
- You could save some meta data
directly into the image file, EXIF
for example, but this is not
supported directly by
OpenCV.
Queries will be hard to do
- At the end you could save the meta
data casting your record as uchar and
writing bytes at the bottom of
your image (may be adding some rows)
but this will be break if you save
the image with lossy file format like
.jpg
