Computation of the Base Two Logarithm of Binary Numbers
IEEE Transactions on Electronic Computers, 1965An approximation to the computation of the base two logarithm of a binary number, realized with binary circuitry, is described. It is known that the logarithm can be obtained approximately from the binary number itself by simple counting and shifting. A method for the reduction of the resulting approximation error by a factor six is given.

Exponentiation Using Binary Logarithms
IETE Journal of Research, 1980A method for digital exponentiation is described. In the method, the binary lg lg (lgN=log2N) of the number (say, z=yz) is computed, The required value (z) is obtained by taking antilogarithm twice. The determination of the logarithm and antilogarithm can be accomplished by simple shifting of the registers in a digital logic, thus the exponentiation ...

Face recognition based on logarithmic local binary patterns
SPIE Proceedings, 2013This paper presents a novel approach to the problem of face recognition that combines the classical Local Binary Pattern (LBP) feature descriptors with image processing in the logarithmic domain and the human visual system. Particularly, we have introduced parameterized logarithmic image processing (PLIP) operators based LBP feature extractor.

Efficient algorithms for binary logarithmic conversion and addition
ISCAS '98. Proceedings of the 1998 IEEE International Symposium on Circuits and Systems (Cat. No.98CH36187), 1999The logarithm number system is an attractive alternative to the conventional number systems when data needs to be manipulated at a very high rate over a wide range. The major problem is deriving logarithms and antilogarithms quickly and accurately enough to allow conversions to and from conventional number representations.
