Abstract: Many geographical applications, medical, etc. are brought to manage images which occupy much place memory and which have similar characteristic to be similar or not very different. Sometimes these latter require to work on areas of images, to make the follow-up of the evolution of same areas in various images, to preserve different states from the same image, Each state corresponding to the result of an operation or a series of particular operations. We present, in this study a solution of this problem, based on the approach of Versions of Data bases, which consists in representing the colour images in the form of trees called Generic tree. This structure minimizes storage by sharing information between the images. This method makes it possible to apply various update operations as research, insertion, suppression and modification of the images simultaneously.
