Compact and Robust Fingerprints Using DCT Coefficients of Key Blocks. Sheng Tang; Jin Tao Li; Yong Dong Zhang. In this paper, we present a novel fingerprinting ...
In this paper, we propose a novel compact image fingerprint extraction method based on canonical correlation analysis (CCA) of local features. After extraction ...
In this paper, we propose a novel image hashing method in the DCT Domain which can be directly extended to MPEG video without DCT transforms. A key goal of the ...
combinations will be smaller depending on the DCT block size and the number of DCT coefficients in one block that are (perceptually and qualitatively) ...
Abstract. An audio fingerprint, which is a compact content-based digest of an audio signal, is widely used to quickly locate perceptually similar songs in ...
This study aims to identify fingerprint images through several steps and extract the features based on DCT technique. The fingerprint image is divided into sub- ...
The solution proposed here is a new joint fingerprinting and decryption method which meets the requirements for both imperceptibility and robustness of ...
