==Quantum image manipulations==

A lot of the effort in QIMP has been focused on designing algorithms to manipulate the position and color information encoded using the '''flexible representation of quantum images (FRQI)''' and its many variants. For instance, FRQI-based fast geometric transformations including (two-point) swapping, flip, (orthogonal) rotations<ref name="Le Fast 2010">{{cite journal |title= Multi-dimensional color image storage and retrieval for a normal arbitrary quantum superposition state |journal= IAENG International Journal of Applied Mathematics |volume=40 |issue=3 |pages=113–123 |year=2010 |last1=Le |first1=P. |last2=Iliyasu |first2=A. |last3= Dong |first3=F. |last4= Hirota |first4=K. }}</ref> and restricted geometric transformations to constrain these operations to a specified area of an image<ref name="Le Strategies 2011">{{cite journal |title= Strategies for designing geometric transformations on quantum images |journal= Theoretical Computer Science |volume=412 |issue=15 |pages=1406–1418 |year=2011 |last1=Le |first1=P. |last2=Iliyasu |first2=A. |last3= Dong |first3=F. |last4= Hirota |first4=K. |url=https://core.ac.uk/download/pdf/82724999.pdf|doi= 10.1016/j.tcs.2010.11.029 }}</ref> were initially proposed.

To illustrate the feasibility and capability of QIMP algorithms and application, researchers always prefer to simulate the digital image processing tasks on the basis of the QIRs that we already have. By using the basic quantum gates and the aforementioned operations, so far, researchers have contributed to quantum image feature extraction,<ref name="Zhang Local 2015">{{cite journal |title= Local feature point extraction for quantum images |journal= Quantum Information Processing |volume=14 |issue=5 |pages=1573–1588 |year=2015 |last1=Zhang |first1=Y. |last2=Lu |first2=K. |last3= Xu |first3=K. |last4= Gao |first4=Y. |last5= Wilson |first5=R. |doi= 10.1007/s11128-014-0842-7 |bibcode= 2015QuIP...14.1573Z |s2cid= 20213446 }}</ref> quantum image segmentation,<ref name="Caraiman Histogram 2014">{{cite journal |title= Histogram-based segmentation of quantum images |journal= Theoretical Computer Science |volume=529 |pages=46–60 |year=2014 |last1=Caraiman |first1=S. |last2=Manta |first2=V. |doi= 10.1016/j.tcs.2013.08.005 |doi-access=free }}</ref> quantum image morphology,<ref name="Yuan Quantum 2015">{{cite journal |title= Quantum morphology operations based on quantum representation model |journal= Quantum Information Processing |volume=14 |issue=5 |pages=1625–1645 |year=2015 |last1=Yuan |first1=S. |last2=Mao |first2=X. |last3= Li |first3=T. |last4= Xue |first4=Y. |last5= Chen |first5=L. |last6= Xiong |first6=Q.|doi= 10.1007/s11128-014-0862-3 |bibcode= 2015QuIP...14.1625Y |s2cid= 44828546 }}</ref> quantum image comparison,<ref name="Yan A 2013">{{cite journal |title= A parallel comparison of multiple pairs of images on quantum computers |journal= International Journal of Innovative Computing and Applications |volume=5 |issue=4 |pages=199–212 |year=2013 |last1=Yan |first1=F. |last2=Iliyasu |first2=A. |last3= Le |first3=P. |last4= Sun |first4=B. |last5= Dong |first5=F. |last6= Hirota |first6=K.|doi= 10.1504/IJICA.2013.062955 }}</ref> quantum image filtering,<ref name="Caraiman Quantum 2013">{{cite journal |title= Quantum image filtering in the frequency ___domain |journal= Advances in Electrical and Computer Engineering |volume=13 |issue=3 |pages=77–84 |year=2013 |last1=Caraiman |first1=S. |last2=Manta |first2=V. |doi= 10.4316/AECE.2013.03013 |doi-access=free }}</ref> quantum image classification,<ref name="Ruan Quantum 2016">{{cite journal |title= Quantum computation for large-scale image classification |journal= Quantum Information Processing |volume=15 |issue=10|pages=4049–4069 |year=2016 |last1=Ruan |first1=Y. |last2=Chen |first2=H. |last3= Tan |first3=J. |url=https://www.researchgate.net/publication/305644388|doi= 10.1007/s11128-016-1391-z |bibcode= 2016QuIP...15.4049R |s2cid= 27476075 }}</ref> quantum image stabilization,<ref name="Yan Strategy 2016">{{cite journal |title= Strategy for quantum image stabilization |journal= Science China Information Sciences |volume=59 |issue= 5 |pages=052102 |year=2016 |last1=Yan |first1=F. |last2=Iliyasu |first2=A. |last3= Yang |first3=H. |last4= Hirota |first4=K. |doi= 10.1007/s11432-016-5541-9 |doi-access=free }}</ref> among others.
