A Weighted ROI-based Image Quality Assessment for WMSN

Zheyuan Xiong, Jiangshan Zhang, Shengyi Wu, Liang Zhang and Min Tu    

Abstract: The major task of WMSN is image communication, which is really a challenge for resource constraint wireless sensors. WMSN should monitor the image distortion by image quality assessment (IQA) to take some adaptive precautions and thus guarantee application quality requirements. Most applications of WMSN require reliable transmission of Region of interest (ROI) in the image. However, little study has been taken on identifying how and to what extent ROI will influence IQA in WMSN. In this work, a simple method is proposed to estimate an image quality by considering the ROI of the image. Different weights are assigned to the primary ROI, secondary ROI and Non ROI parts of the image in the quality evaluation phase. The simulation results have shown that the proposed IQA has better performance than state-of-the-art IQA methods for WMSN.
