| Abstract | This paper presents the algorithm development for detecting the Styrofoam beads in the adapter card image. The proposed method has three steps: (1) the process of constructing the template image of the adapter card;(2) the process of preparing testing images;which includes with selecting region of interest;adjusting the power level of the image and converting the testing image into a binary image by using the Otsu method;and (3) the process of detecting the Styrofoam beads;which includes with subtracting the testing image with the template image;labeling and connecting objects pixels in order to determine the location of the Styrofoam beads;filtering noise and using the threshold value in the decision making process. From experimental results;these show that the most satisfactory result for detecting the Styrofoam beads of the proposed algorithm occurs when the number of pixels for the connected object position is more than 25 pixels;the structure element is a square of 4 x 4 pixels;and the threshold value is equal to 111.50. In addition;the efficiency of proposed method provides the four following quantitative measures. The value of the sensitivity is equal to 98.46%;the value of the specificity is equal to 96.00%;the value of the accuracy is equal to 96.60%;and the value of the precision is equal to 88.89%.. |
