(English Abstract)
In Wireless Multimedia Sensor Networks (WMSNs), authentication of multimedia data is very important because the data can be used in making crucial decisions. This study evaluates interest point detectors in terms of resilience to channel error occurred in WMSNs, robustness to JPEG compression, and sensitivity to image tampering. SIFT, SURF, ORB, AKAZE, SADDLE and HOG were evaluated with USC-SIPI image database by computing recall and precision between the original images and modified images by channel errors and JPEG compression and tampering. In addition, median filter and Gaussian filter were applied to reduce channel error and quantization errors from JPEG compression respectively and produced significant performance. AKAZE showed best performance for all conditions of experiments. The evaluation of interest point detectors showed the possibility of their application to authentication in WMSNs.
