1. A process for treating an image of an object defined by pixels, the image being acquired at an instant t comprising: receiving a first image of the object at an instant t−2; receiving a second image of the object at an instant t−1; generating first and second primary images based on the second image, and first and second moving vectors, respectively; determining a predicted image of the object at the instant t as a function of the first and second primary images and the first image; and generating a visualized image corresponding to a function of both the predicted image and the image of the object acquired at the instant t, so as to attenuate a noise of the image of the object acquired at the instant t.
