        Wireless sensor networks are a large number of sensor nodes with limited energy in a scattered geographically limited area. Due to limited resources in wireless sensor networks, increasing the lifetime of the networks by reducing energy consumption is always considered. More nodes to send data to the central station energy consumption. Sequential routing based on clustering, this responsibility falls on the head, and this increases the energy consumption of cluster heads. In recent years later all the energy of cluster heads, routing protocols and a lot of clustering is proposed. The purpose of this study, the combination of clustering and routing in order to extend the lifetime of this type of network. For clustering of genetic algorithm with fixed and harmony search algorithm is used for routing. Customize search algorithm for routing in harmony, three criteria neighborhood, reducing energy consumption and proper distribution of energy consumption is taken into account. Harmony algorithm is proposed to establish a proper balance between the criteria listed will generate more efficient routes. Finally change the routing cluster heads in each round will be balancing energy consumption between nodes per cluster. The results of the tests show the superiority of 2.14% proposed increase in messaging as well as 24.84% Lifetime network protocol is DEEC. Manuscript profile

        One of the sciences in order to increase the efficiency of intelligent systems to be used in the visual sense, is Machine vision science. The first step in many applications in machine vision is image segmentation. Image segmentation, refers to the grouping of pixels in an image So that these pixels, the same qualities have with each other And the pixels adjacent parts, have different characteristics. The most important feature used in image segmentation, colors and features. In monochrome images, the gray level is considered as properties But color images, different color spaces used as a color feature. In this study, the color and texture features for image segmentation is considered. Clustering-based methods of are used in image segmentation methods and Gaussian function is similar measure in clustering images. Spectral clustering requires has high computational cost. To save time and accelerate the segmentation of images Using clustering with Super pixels will achieve optimal results And to achieve reliable results approximate and fuzzy algorithm is used. The proposed algorithm is applied on several standard image And the evaluation criteria,Evaluated and evaluated by the indicators are evaluated and compared. The results of the experiments were compared to other fragmentation methods, suggesting a 3.4% superiority in the segmentation accuracy of the proposed algorithm, and all the evaluation indicators of the study have increased to a satisfactory level.
