<P>PROBLEM TO BE SOLVED: To provide a method of measuring a shape of hair by which various kinds of measurements is carried out smoothly by picture processing by grasping the shape of hair easily from picture data of a section to be tested. <P>SOLUTION: The method consists of a first step 15 for storing the picture data obtained by photographing a section including the section to be tested 28, and a second step 17 for extracting an area 16 including a hair picture from the picture data and carrying out picture processing. The second step 17 comprises a first sub step 18 for calculating the gradation of brightness of two orthogonal directions of each pixel in the area 16 including the hair picture, a second sub step 19 for calculating a main direction of each pixel from the gradation, a third sub step 20 for calculating a representative value of a main direction in an neighboring area of each pixel, and a fourth sub step 21 which compares pixel values of each pixel in a direction orthogonal to the direction of the representative value to take a maximum or minimum value and calculates an area of a pixel where an average value of gradations in the neighboring area is not smaller than a threshold as a skeleton area 22 to judge continuity of the hair from that of the skeleton area 22. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
