Too many small and too many wrong regions have been found. So we have to eliminate them by using ×ÐØ ×Ô. Figure 5.14 shows the final result of the segmentation on the right side. 5.8 Cell Walls File name: ÛÓÓ ÐÐ×ºÚ In this example we will examine the alteration of the cell wall’s proportion during a tree’s growth. The input image is a microscope view of wooden cells (see figure 5.15). You can clearly see the single cells and the discontinuity that is caused by the stopped growing in winter. Extracting cell walls is simple because they are significantly darker. The remaining “difficulty” lies in the computation of the distribution in growth direction, i.e., along the image x-axis. First, we define the width of the window over which the cell distribution is computed by assigning it to the variable in the program. Then we fetch the image size using Ø Ñ ÔÓÒØÖ½ to get the corresponding loop parameters. The broader the search range, the stronger the smoothing during the measurement. Now the loop starts from the “left” side to compute the whole image. The ratio of the area of the cell walls and a rectangle of width is computed for every value of the loop variable .

To allow further processing of the data (such as for plotting using ÒÙÔÐÓØ as in figure 5.16) it has to be written to a file. Therefore, a text file is opened first (ÓÔÒ Ð). Now you can write to this file by using ÛÖØ ×ØÖÒ and ÒÛ ÐÒ. Note the formatting of output when using ÛÖØ ×ØÖÒ. The output text starts with the loop variable that is followed by a space HALCON 6.0
