Abstract
Classification process for a colour image with a view to determining the shot location, i.e. exterior or interior, consisting in particular of the following: determining spectral bands of reference colours B.sub.i corresponding to different image temperature values allowing for the characterisation of an exterior image or an interior image, selecting a colour image to be analysed, digitising the selected colour image so that it can be defined in a given colour area (for example RGB), determining at least for the spectral bands of the reference colours the distribution of colour spectrums of at least part of the digitised colour image, and analysing the colour spectrums of the digitised image in order to determine the temperature of the image corresponding to an interior image or an exterior image depending on their distribution according to the spectral bands of reference colours.
