<p>PURPOSE: To easily execute highly accurate topographical geological analysis and sorting by calculating a distance between picture data in an area to be processed and feature teacher data based upon a texture feature parameter value(TP) extracted from the picture to be processed. CONSTITUTION: When an SAR picture is fetched from an artificial satellite, plural interesting areas are set up and teacher data are extracted (S1) and a TP from a set area is calculated (S2). The calculated TP is weighted and plural teacher data in a near distance are grouped based upon a difference value between respective TPs (S3 to S5). Teacher data having the longest distance from teacher data in another group are set up as feature teacher data in each group (S6). then a TP in each teacher data size of the whole picture is calculated and a distance bewteen the calculated TP and each feature data is calculated (S7). Then feature teacher data having the nearest distance are grouped in the same sort and texture sorting is successively executed (S9).</p> |
