In this work, we consider the problem of detecting target objects in remote sensing imagery; such as detecting rooftops, trees, or cars in color/hyperspectral imagery. Many detection algorithms for this problem work by assigning a decision statistic (or “confidence”) to all, or a subset, of spatial locations in the data. A threshold is then applied to the statistics to identify detections. The detection...
Existing studies suggest the vulnerability of fingerprint verification system against spoof attacks. A spoofing attack occurs when an adversary mimics the biometric trait of another individual for illegitimate access and advantages. Liveness detection algorithms aim to detect live fingerprint samples from the fake artifact. A variety of materials, such as latex, gelatine and silicone, can be used...
