Quantum classifier for recognition and identification of leaf profile features

Image processing using the quantum quaternion Fourier transform

“…In our work, we show the theory and applications of the QQFT. In the works of the last period of 2021 to 2022 [3][4][5], the authors used just QCFT. With these comparisons shown in Table 1, we conclude that in general, the results of the QCFT are shown in all cases to be similar to those of the FFT.…”

“…The authors used the QCFTand the quantum complex wavelet transform and proposed a quantum image scaling scheme based on the extension of the bilinear interpolation method. Kumar et al [3] apply a quantum classifier to a computer vision system for leaf recognition which can be applied to a quantum computer. Images from 10 species of leaves, which are categorized into two groups, namely, simple and palmately, are recognized using a quantum classifier.…”

“…Our article proposes for the first time the QQFT. Until recent years, authors have developed and applied only the QCFT [3,[5][6][7][8][9]. We can say that all the applications done using the QCFT can be improved using the QQFT, because the QCFT uses a 2D representation of the data as a qubit, in contrast, the QQFT represents the data in 4D using a two-qubit Q q = s|00 > +r|01 > +g|10 > +b|11 >, as a result, the processing is much more efficient in the framework of the quaternion algebra.…”

Poly(O‐Toluidine)‐polyvinylpyrrolidone copolymer submerged MgFe2O4/CS‐OXSWCNTs nanocomposite for removal of acid red dye from aqueous solutions

“…By adding acids like HCl or H 2 SO 4 , the POT can be easily modified and made more effective in attracting dye molecules and nanoparticles. The process of adding these acids, known as doping, can be controlled by adding reversible acids or bases to enhance the adsorption properties of POT 31–34 . However, the long chains have a tendency to aggregate, which decreases the amount of surface area and active sites that are available for adsorption and is a disadvantage of using POT 35,36 .…”
