Hadamard Walsh space based hybrid technique for image data augmentation [PDF]
Image data augmentation (IDA) is common when deep learning is used for image classification to address the issue of overfitting. Overfitting occurs when the datasets are small and the deep learning models have a huge capacity. Overfitting models have low

An efficient no‐reference image quality analysis based on statistical perceptual features
IET Image Processing, Volume 19, Issue 1, January/December 2025.1. A novel and efficient feature‐based no‐reference image quality assessment (NR‐IQA) focus measure is proposed. 2. It is based on the statistical structural and texture features of the image. 3. The logarithmic entropy‐based focus measure shows promising results as compared to the existing techniques. Abstract It is well known that image quality needs

Cache Conscious Walsh-Hadamard Transform
, 2001 The Walsh-Hadamard Transform (WHT) is an important algorithm in signal processing because of its simplicity. However, in computing large size WHT, non-unit stride access results in poor cache performance leading to severe degradation in performance ...

REGULAR METHOD FOR SYNTHESIS OF BASIC BENT-SQUARES OF RANDOM ORDER
Наука и техника, 2016 The paper is devoted to the class construction of the most non-linear Boolean bent-functions of any length N = 2k (k = 2, 4, 6…), on the basis of their spectral representation – Agievich bent squares.

Faster ridge regression via the subsampled randomized Hadamard transform [PDF]
, 2013 We propose a fast algorithm for ridge regression when the number of features is much larger than the number of observations (p n). The standard way to solve ridge regression in this setting works in the dual space and gives a running time of O(n2p). Our

A family of fast walsh hadamard algorithms with identical sparse matrix factorization
, 2006 In this letter, we present a family of fast Walsh Hadamard transform algorithms that have an identical and iterative stage factorization. We show the transform factorization in terms of identical sparse matrices that implement the stages of general radix-

A Method for Diagnosing Gearboxes of Means of Transport Using Multi-Stage Filtering and Entropy
Entropy, 2019 The paper presents a method of processing vibration signals which was designed to detect damage to wheels of gearboxes for means of transport. This method uses entropy calculation, and multi-stage filtering calculated by means of digital filters and the ...

A NEW DISCRETE HARTLEY TRANSFORM PRECODING BASED INTERLEAVED-OFDMA UPLINK SYSTEM WITH REDUCED PAPR FOR 4G CELLULAR NETWORKS [PDF]
Journal of Engineering Science and Technology, 2011 High peak-to-average power ratio (PAPR) reduction is one of the major challenges in orthogonal frequency division multiple access (OFDMA) systems since last decades. High PAPR increases the complexity of analogue-to-digital (A/D) and digital-to-analogue (
