This paper presents a new supervised method for vessel segmentation in retinal images. This method remolds the task of segmentation as a problem of cross-modality data transformation from retinal image to vessel map. A wide and deep neural network with strong induction ability is proposed to model the transformation, and an efficient training strategy is(More)
When the scale-invariant feature transform (SIFT) is adopted in the registration of remote sensing images, a lot of incorrect matches of keypoints will appear owing to the significant difference in the image intensity between remote sensing images compared to visible images. Scale–orientation joint restriction criteria are proposed to achieve robust feature(More)
Digital fingerprinting is a technique for identifying users who use multimedia content for unintended purpose, such as  redistribution. In order to characterize the fingerprints that can withstand collusion attack, Dittmann et. al proposed the definition of Anti-Collusion Codes (ACCs). In this paper, we present a new approach to construct(More)
In this paper, we present a provably secure routing protocol for wireless sensor networks, called S-SPIN (Secure-SPIN), that is a security extension of SPIN. The MAC scheme is introduced to guarantee the correctness and integrity of the messages. And we prove that under the formal security framework proposed by Acs et al, by using a mathematically rigorous(More)
Body temperature is a crucial vital sign, detecting and recording patients' body temperature can be very helpful for diagnosis and treatments. The widely used thermometers nowadays are not capable to continuously detect body temperature, and the geographic range of data transmission is also restricted. This paper develops a GPRS-based wearable thermometric(More)
