BlowfishEncryption.rar - Blowfish Algorithm is a Feistel Network, iterating a simple encryption function 16
times. The block size is 64 bits, and the key can be any length up to 448 bits. Although
there is a complex initialization phase required before any encryption can take place, the
actual encryption of data is very efficient on large microprocessors.
Blowfish is a variable-length key block cipher. It is suitable for applications where the
key does not change often, like a communications link or an automatic file encryptor. It is
significantly faster than most encryption algorithms when implemented on 32-bit
microprocessors with large data caches.,2011-06-09 18:03:09,下载74次
A-Novel-Image-Interpolation-Method.rar - the noise deteriorates the
interpolation performance in digital images, it is effective to
employ denoising prior to the interpolation. In this paper, we
propose a novel interpolation framework in which denoising
and image sharpening methods are embedded. In the
proposed framework, the image is first decomposed using the
bilateral filter into the detail and base layers which represent
the small and large scale features, respectively. The detail
layer is adaptively smoothed to suppress the noise before
interpolation and an edge-preserving interpolation method is
applied to both layers. Finally, the high resolution image is
obtained by combining the base and detail layers.
Experimental results show that the proposed algorithm
outperforms the conventional methods,2011-06-09 18:00:48,下载43次
