This paper try to demonstrate the usefulness of image processing techniques in order to measure some relevant features of Tree Drawing Test's images. The segmentation of the trunk from the crown & roots is performed using profilograms. Then the length and height of each part are measured, and the data are employed for the computations of the standard TDT formulas. This automatic process can be a real help for large groups of under aged children psychological screening.
