Is Your Baking Powder Still Good?

There's an expiration date that helps, too. Good to know that tip, though - thanks for posting!
Although I'm one of those persons who uses things after they've expired, since I trust my nose.One thing I noticed, last time I bought baking powder, is the cans are a lot smaller. Great idea, since I don't use baking powder as near often as I use baking soda. Less to throw out when it does get old!

The method comprises the steps of: capturing an image of the environment of a vehicle; extracting at least one feature from the captured image; classifying the at least one feature as being a part of a structure of interest or not; and performing a further operation based on the classification of the at least one feature. The classification is based on a probabilistic model of the structure of interest. The probabilistic model is defined by a plurality of features, each feature having a respective probability distribution of pixel values. The further operation is performed if the probability that the feature is a part of the structure of interest is above a predetermined threshold. The apparatus comprises an image sensor (1), a feature extractor (2), a classifier (3), and a controller (4). The controller is configured to perform the steps of the method.(FR) L'invention concerne un procédé et un appareil de détection et d'identification d'une structure d'intérêt. Le procédé comprend les étapes consistant à : capturer une image de l'environnement d'un véhicule ; extraire au moins une caractéristique de l'image capturée ; classifier ladite au moins une caractéristique en tant qu'étant une partie d'une structure d'intérêt ou non ; et effectuer une autre opération sur la base de la
