In this paper, a fuzzy logic based digital image watermarking technique is proposed. The contrast and edge values of the host image are analyzed by the fuzzy inference system (FIS) against fuzzy rules and then the FIS evaluates the output which is proposed as the watermarking strength (α) of the image. By varying the contrast and edge values of the host image, the fuzzy logic adjusts the watermarking...
Screening of atrial fibrillation (AF) for high-risk patients including all patients aged 65 years and older is important for prevention of risk of stroke. Different technologies such as modified blood pressure monitor, single lead ECG-based finger-probe, and smart phone using plethysmogram signal have been emerging for this purpose. All these technologies use irregularity of heartbeat duration as...
Heartbeat signal is an emerging biometric modality which is getting attention for its robustness against spoof attack. Introducing heartbeat into a fingerprint biometric system can yield promising results in two ways. First, it may increase the accuracy of the biometric system and second it may increase its robustness against spoof attacks. In this paper, a score level fusion is used based on the...
In this paper, an entropy based feature extraction algorithm for face recognition is proposed, which efficiently exploits the local spatial variations in a face image. Instead of considering the entire face image as a whole, first considering small segments of image along vertical direction, the entropy values are measured for each segment and thereby a vertical signature is obtained. It is shown...
