Affine-invariant scene categorization
, 2014 This paper presents a scene categorization method that is invariant to affine transformations. We propose a new moment-based normalization algorithm to generate an output image that is independent of the position, rotation, shear, and scale of the input ...

Irrigation and Drainage, EarlyView.ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Aspects of the affine superalgebra sl(2|1) at fractional level [PDF]
, 2001 Aspects of the Affine Superalgebra sl(2|l) at Fractional Level Ph.D. Thesis by Gavin Balfour Johnstone, April 2001 In this thesis we study the affine superalgebra sl(2|l; C) at fractional levels of the form k = l/u-l,uєN\{l}.

Irrigation and Drainage, EarlyView.ABSTRACT This study develops an integrated simulation–optimization framework for sustainable crop allocation and water resource management in the Bargarh Canal Command (BCC), eastern India. Efficient irrigation allocation remains a critical challenge due to competing demands, groundwater–surface water interactions and environmental constraints ...

Affine invariant texture signatures
, 2001 We develop a new approach for texture classification independent of affine transforms. Based on a spectral representation of texture images under affine transform, anisotropic scale invariant signatures of the orientation spectrum distribution are ...

Affine invariant triangulations [PDF]
, 2019 We study affine invariant 2D triangulation methods. That is, methods that produce the same triangulation for a point set S for any (unknown) affine transformation of S.

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays
Journal of Combinatorial Designs, EarlyView.ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Quaternary Affine-Invariant Codes [PDF]
, 2015 This thesis concerned with extended cyclic codes. The objective of this thesis is to give a full description of binary and quaternary affine-invariant codes of small dimensions. Extended cyclic codes are studied using group ring methods. Affine-invariant
