Hello everyone,

I need some help...

I have an image of a refrigerator... There is some bottles
and other stuff.

What should do to know which object is it, which colour is
it, and other features...

This usually requires the refrigerator toolbox,
although the freezer toolbox will sometimes be
acceptable, depending on the contents. There
are also quite general cooking toolboxes, but
they may have more functionality than you
really need.

cooktave has a free icebox toolbox that Cem could extend...

Maybe you could use the FAM method ... better known as the
Finite Ale-Mount method .. for solving this problem:

"100 finite ales in the fridge,
100 finite ales,
take one down,
Galerkin around,
99 finite ales in the fridge"

For more details, see:

http://en.wikipedia.org/wiki/Galerkin_method
http://en.wikipedia.org/wiki/Cask_ale

Alas, there is no such thing as an Infinite Ale-Mount
solution ... one must be content with finite discretizations.

Any finite ale-mount solution can be transformed into an
infinite ale-mount solution by using function divided by
its finite infinite integral for the proportional rate of flow.
For cask ale, a function based upon logs would be particularily
appropriate.

Cem NAMAZCI:
As you can see from the other entertaining responses, we like to have
a bit of fun with those who don't provide enough information to answer
their question. For example, for some reason you forgot to post some
images of your refrigerator. I don't even know if the door to the
refrigerator is open or closed! (If it's closed, you'll need the Mind
Reading Toolbox, which is a very useful one one to have.) We will
need at least 2 or 3 typical images that you expect to encounter
before we can give you any hint of an algorithm. Object recognition
can be an incredibly complex task, or it can be incredibly easy,
depending on what the image looks like. Is your object on a cluttered
background? Can you find it based on color or shape or both? Maybe
classifying objects depends on texture or size or any one of hundreds
of other parameters. So, basically we're not getting any further
until you post an image somewhere that we can look at.
Regards,
ImageAnalyst

And if the door is open, we need to know whether the little light
in the refrigerator has burnt out, or if the switch is sticking again.

The complexity of modelling the refrigerator light is one of the
major differences between the Mathworks refrigerator toolbox
and the free cooktave icebox toolbox (which, of course, does not
have a light.)

Thanks for the tips. I've always liked the Sears line myself. They
make nice refrigerators in their Kenmore brand, plus very nice
toolboxes in their Craftsman brand. They're pricey, but like you
pointed out, often you get what you pay for.
