Cardiac arrhythmia indicates abnormal electrical activity of heart that can be a great threat to human. So it needs to be identified for clinical diagnosis and treatment. Analysis of ECG signal plays an important role in diagnosing cardiac diseases. An efficient method of analysing ECG signal and predicting heart abnormalities have been proposed in this paper. In the proposed scheme, at first the...
Histogram shifting is one of the most useful techniques of Reversible Data Hiding (RDH). In histogram shifting based data hiding technique, lower distortion and improved capacity can be achieved. In this paper, a new method of reversible data hiding based on compressed gray level histogram shifting has been proposed which provides a high capacity of data hiding and also maintains a good image quality...
