On minimum error thresholding and its implementations
Pattern Recognition Letters, 1988Abstract In this paper we discuss the thresholding methods [1] due to Kittler and Illingworth. Two methods are suggested in [1], namely, 1) minimizing a criterion function aand 2) iterative search of the minimum error threshold. We have tested the two methods.

Thresholding implemented in the frequency domain
IEEE Transactions on Image Processing, 2001Image processing procedures are usually carried out in the spatial domain where the images are acquired and presented/utilized. The linear nature of the Fourier transform allows only those operations that are linear to be mapped into the frequency domain.

Design and Implementation of a Parallel Markowitz Threshold Algorithm
SIAM Journal on Matrix Analysis and Applications, 2020We develop a novel algorithm for the parallel factorization of an unsymmetric sparse matrix using a Markowitz threshold algorithm. Our algorithm uses a significant extension of a maximum independent set algorithm of Luby to select a block of independent pivots in parallel. We then use this block to update the matrix again in parallel.

Review of Capacitive Threshold Gate Implementations
2003This is an in-depth survey paper on capacitive hardware implementations of threshold logic gates. The different VLSI solutions include the switched capacitor and the floating gate and their variations. It will be shown how the distinct original proposals from both categories have evolved to become quite similar.

On Non-Completeness in Threshold Implementations
Proceedings of ACM Workshop on Theory of Implementation Security Workshop, 2019In this note we study non-completeness, the key property of Threshold Implementations (TIs). TIs have proved to be a popular method for mitigating side-channel leakage of sensitive information in hardware implementations of cryptographic algorithms. In particular, we provide a reformulation of non-completeness in terms of set coverings with constraints,

VLSI implementations of threshold logic- a comprehensive survey
IEEE Transactions on Neural Networks, 2003This paper is an in-depth review on silicon implementations of threshold logic gates that covers several decades. In this paper, we will mention early MOS threshold logic solutions and detail numerous very-large-scale integration (VLSI) implementations including capacitive (switched capacitor and floating gate with their variations), conductance ...

Affine Equivalence and Its Application to Tightening Threshold Implementations [PDF]
Lecture Notes in Computer Science, 2016 Motivated by the development of Side-Channel Analysis SCA countermeasures which can provide security upi¾?to a certain order, defeating higher-order attacks has become amongst the most challenging issues. For instance, Threshold Implementation TI which nicely solves the problem of glitches in masked hardware designs is able to avoid first-order ...

CMOS Implementation of Generalized Threshold Functions
2003Threshold Logic (TL) gates can evaluate any linearly separable function via the computation of a weighted sum over the input variables. In this paper we generalize this mechanism and introduce the novel concept of k-order Generalized Threshold Logic (GTL) gates.

Threshold Implementations in Industry
Proceedings of the 2016 ACM Workshop on Theory of Implementation Security, 2016Implementing efficient countermeasures against side-channel attacks is a challenge since two decades. Especially in hardware, many masking countermeasure implementations failed due to first-order leakages caused by glitches or other effects such as early evaluation and unbalanced routing.

Dividing the threshold: Multi-probe localized EM analysis on threshold implementations
2018 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), 2018Cryptographic implementations typically need to be secured to retain their secrets in the presence of attacks. As a countermeasure to prevent side-channel attacks, threshold implementations are a commonly encountered concept. They resemble a multi-party computation, where the value is split in independent shares and processed separately.
