dc.description.abstractSUGAR MAPLE LOGS (ACER SACCHARUM MARSH.) WERE SCANNED USING X-RAY MEDICAL SCANNER IN ORDER TO DEVELOP A CLASSIFICATION PROCEDURE FOR THIS TYPE OF IMAGERY (CT IMAGES). THE CLASSIFICATION PROCEDURE WAS REQUIRED IN ORDER TO SEPARATE SAPWOOD FROM COLORED HEARTWOOD, KNOTS, ROT AND BARK. FIVE LOGS COMING FROM A FRESHLY CUT TREE (GROUP 1) AND THREE LOGS SAMPLED FROM A SAWMILL YARD (GROUP 2) WERE CHOSEN FOR THIS PURPOSE. TWO PARAMETRIC SUPERVISED CLASSIFICATION ALGORITHMS, A MINIMUM DISTANCE (MDC) AND MAXIMUM LIKELIHOOD (MLC) ONES, WERE QUALITATIVELY AND QUANTITATIVELY TESTED AND THE RESULTING THEMATIC MAPS WERE FILTERED BY A 5×5 MEDIAN FILTER.
