Nous avons effectué les tests en tenant compte des paramètres utilisés afin de mettre en évidence leur influence. Sur les deux images testées, nous avons constaté que l’espace colorimétrique utilisé pour calculer la différence colorimétrique entre deux régions (RVB ou L * a * b * ) ainsi que le mode de segmentation (progressive ou par priorité) influent sur les résultats de segmentation. Nous avons mis aussi en évidence l’importance du seuil, qui est décisif sur les résultats que l’en veut atteindre. Nous pouvons également con

说明：  BCH 编解码的MATLAB 实现。BCH码是一类重要而有效的纠正多个随机错误的循环码，由于该码具有严格的代数结构，所以是到目前为止研究得最为详尽、应用最为广泛的一类码，已有多种译码算法。(BCH codec of MATLAB. BCH is a kind of important and effective redress the wrong number of random cyclic code, as the code strictly algebraic structure, it is so far the most detailed study in, the most widely used type of a code has a variety of decoding algorithm.)

This paper deals with analysis of main functional diagrams of step PID controllers for electric motor-driven actuators. The main formulae to calculate the parameters of the diagrams of step PID controllers are presented in the paper. The influence of these parameters on the transient processes in step controllers and on the output position of the actuator is analyzed. Transient processes in step controllers with motor-driven actuators are simulated in PI and PID control mode. These transient processes are compared to the transient processes in continuous controllers. The accuracy of step PID controllers is analyzed, and restrictions on the parameters of step PID controllers are presented. The diagrams of step PID controllers considered in this paper can be implemented in the up-to-date PLCs software for automatic control using the electric motor-driven actuators in the control loops.
