ABSTRACT
Panoramic images are important for video surveillance of Wireless Multimedia Sensor Networks (WMSN). The traditional image mosaicking approaches always accompany lots of energy and bandwidth consumption, which are not suitable for resource-constrained WMSN. For sufficient utilization of constraint resources on generating high-resolution images with wide field of view, a cooperative image mosaicking algorithm among multiple video nodes is proposed. Image block searching algorithm is applied for image registration to decrease the energy consumption, sum of absolute difference algorithm is adapted to improve the accuracy of image registration and weighted mean algorithm is applied for image stitching. Data volumes of transmission are decreased after image mosaicking, which can efficiently reduce the network loading. Simulation results demonstrate that the computation complexity of proposed algorithm is lower than other image mosaicking algorithms, under certain image registration accuracy and image quality.
