Visual sensornetworks are networks composed of very large number of visual sensors (camera).The cameras are installed in different location of a wide area to captureimages of targeted object. These images must be transmitted to a centralizedserver hop by hop through the sensor network. Before transmission the imagesshould be kept small by applying a large compression ratio which may degradeimage quality, hence to reduce the energy used in transmission. Here camera-equippedsensors are taking pictures of same object and the pictures of adjacent cameramay overlap. It can be demonstrated by allowing intermediate sensors to processthe images and combine the overlapping portions, this reduce the total energyspent on transmission. Simulation results that show the tradeoff between energyconsumption and image quality are generated using matlab.
