We propose a no-reference sharpness metric that employs the concept of inherent sharpness. It provides a perceptual sharpness score based on wavelet coefficients. The proposed metric is highly correlated with subjective sharpness evaluations and outperforms other state-of-the-art metrics.
Software birthmarks are unique and native characteristics of a binary executable program that can be used for detecting software piracy. API (Application Programming Interface) calls in an MS Windows binary executable can be used as software birthmarks when there are no source codes available to detect software similarity. However, it is inefficient to… (More)
