| Abstract | ||
| In this paper, we determine the optimal edge detection threshold value. This has done by extracting small homogenous blocks from unequal mean regions. Then, from these blocks, we generate small image with known edges. So, these simulated edges compared with the detected edges from edge detector method for different threshold values by computing mean square errors between them. The mean square error computed for the total edge image points (Er), where we used this measure to determine the best threshold value (tho | ||
