Cryptanalysis of MDC-2
We provide a collision attack and preimage attacks on the MDC-2 construction, which is a method (dating back to 1988) of turning an n-bit block cipher into a 2n-bit hash function. ...

Face Shape Reconstruction from Image Sequence Taken with Monocular Camera using Shape Database
We propose a method for reconstructing 3D face shape from a camera, which captures the object face from various viewing angles. In this method, we do not directly reconstruct the ...

Polish parsers, step by step
We present the derivation of a space efficient parser combinator library: the constructed parsers do not keep unnecessary references to the input, produce online results and effic...
