Each q-ary symbol in a codeword of the UEC ode is mapped to a codeword of a block modulation code. Conventional error control codes, such as Reed-Solomon codes, BCH codes, and Fire codes, are not suitable for such two-dimensional storage media because they require a large number of check bits to provide a uniform error correction strong enough to correct errors in the edge of the media. In contrast, two-level binary unequal error control (UEC) codes are suitable for this type of storage media because a codeword of the UEC code has two disjoint areas with distinct error control capabilities: the area X0 with a strong error control capability and the remaining area X1 with a moderate error control capability. In addition to the error control codes, optical storage systems employ modulation codes to improve the signal-to-noise ratio (SNR) of the readout signals and nally to reduce the BER of the readout data. Typical modulation codes applied to the holographic memories are the balanced codes, the low-pass ltering codes [BURR97], and the sparse modulation codes [KING00]. A balanced code is a block code of length n whose codewords have a constant Hamming weight bn=2c, where bxc shows the largest integer less than or equal to x. These codes are effective in reducing the errors that occur in the binarization stage of the readout gray-scale signal. That is, these gray-scale signals can be binarized without using.Related: QR Code Generating .NET WinForms Data, QR Code Generating ASP.NET Data, Excel QR Code Generation Size

positions will cause the swarm never to reach an equilibrium state While not all the methods discussed below consider this fact, all of the methods can address the problem by reducing the amount of chaos over time Kennedy and Eberhart [449] were the rst to mention the advantages of randomly reinitializing particles, a process referred to as craziness Although Kennedy mentioned the potential advantages of a craziness operator, no evaluation of such operators was given Since then, a number of researchers have proposed di erent approaches to implement a craziness operator for PSO When considering any method to add randomness to the swarm, a number of aspects need to be considered, including what should be randomized, when should randomization occur, how should it be done, and which members of the swarm will be a ected Additionally, thought should be given to what should be done with personal best positions of a ected particles These aspects are discussed next The diversity of the swarm can be increased by randomly initializing position vectors [534, 535, 863, 874, 875, 922, 923] and/or velocity vectors [765, 766, 922, 923, 924] By initializing positions, particles are physically relocated to a di erent, random position in the search space If velocity vectors are randomized and positions kept constant, particles retain their memory of their current and previous best solutions, but are forced to search in di erent random directions If a better solution is not found due to random initialization of the velocity vector of a particle, the particle will again be attracted towards its personal best position If position vectors are initialized, thought should be given to what should be done with personal best positions and velocity vectors Total reinitialization will have a particle s personal best also initialized to the new random position [534, 535, 923] This e ectively removes the particle s memory and prevents the particle from moving back towards its previously found best position (depending on when the global best position is updated) At the rst iteration after reinitialization the new particle is attracted only towards the previous global best position of the swarm Alternatively, reinitialized particles may retain their memory of previous best positions It should be noted that the latter may have less diversity than removing particle memories, since particles are immediately moving back towards their previous personal best positions It may, of course, happen that a new personal best position is found en route When positions are reinitialized, velocities are usually initialized to zero, to have a zero momentum at the rst iteration after reinitialization Alternatively, velocities can be initialized to small random values [923] Venter and Sobieszczanski-Sobieski [874, 875] initialize velocities to the cognitive component before reinitialization This ensures a momentum back towards the personal best position The next mportant question to consider is when to reinitialize If reinitialization happens too soon, the a ected particles may not have had su cient time to explore their current regions before being relocated If the time to reinitialization is too long, it may happen that all particles have already converged This is not really a problem, other than wasted computational time since no improvements are seen in this state Several approaches have been identi ed to decide when to reinitialize:.

In this case a particle is attracted more to its better neighbors A disadvantage of the FIPS is that it does not consider the fact that the in uences of multiple particles may cancel each other For example, if two neighbors respectively contribute the amount of a and a to the velocity update of a speci c particle, then the sum of their in uences is zero Consider the e ect when all the neighbors of a particle are organized approximately symmetrically around the particle The change in weight due to the FIPS velocity term will then be approximately zero, causing the change in position to be etermined only by vi (t) Barebones PSO Formal proofs [851, 863, 870] have shown that each particle converges to a point that is a weighted average between the personal best and neighborhood best positions If it is assumed that c1 = c2 , then a particle converges, in each dimension to yij (t) + yij (t) 2 (1656).

If there were no errors, the original codeword would be obtained However, since errors are unavoidable in biometrics, the result of the XOR will differ from the correct codeword Here the ECC decoder comes into play: If the number of errors is not too large, the ECC can correct all the errors and obtain the original codeword Since the codewords are deterministically mapped to 140-bit keys, the correct 140-bit key will be retrieved If, on the other hand, the number of errors exceeds the ECC s capability, the decoder will declare a failure Therefore, the output of BE algorithm is either a key or a failure message Ideally, the failure should be output for an impostor only; however, it could happen for a legitimate user as well that is, the system could have a false rejection, as in conventional biometrics.
