1. A process for treating an image of an object defined by pixels, the image being acquired at an instant t comprising: determining a predicted image of the object at the instant t as a function of the images of the object acquired at the instants t-i, i being a positive whole number greater than or equal to 1; moving of each of layers constituting the image acquired at the instant t, the number of layers being previously fixed and the moving of each of the layers being previously determined; and generating the visualized image corresponding to a function of the predicted image and the image of the object acquired at the instant t, so as to attenuate the noise of the image of the object acquired at the instant t.
