Maximum entropy image restoration I The entropy expression

摘要: The two entropy expressions, log B and −B logB (where is the local brightness of object or its spatial spectral power) used in maximum (ME) image restoration, are derived as limiting cases a general formula. represented by n photons emitted from small unit area imaged receiver. These can be distributed over z degrees freedom q(n,z) different ways calculated Bose-Einstein statistics. to maximized interpreted, original definition Boltzmann Planck, logq(n,z). This expression reduces limits n⪢z>1 n⪡z, respectively. When interpreted an average n¯ ensemble, above criteria remain same (with replaced n¯), addition for = 1 case expression, ME power estimation, n¯⪢z=1.
