This study introduces the quaternion Krawtchouk moments, QKrMs, as a new set of moments to represent color images. Krawtchouk moments (KrMs) represent one type of discrete moments. QKrMs use traditional Krawtchouk moments of each color channel to describe color images. This new set of moments is defined by using orthogonal polynomials called the Krawtchouk polynomials. The stability against the translation, rotation, and scaling transformations for QKrMs is discussed. The performance of the proposed QKrMs is evaluated against other discrete quaternion moments for image reconstruction capability, toughness against various types of noise, invariance to similarity transformations, color face image recognition, and CPU elapsed times.<\/jats:p>","DOI":"10.1142\/s0219467822500371","type":"journal-article","created":{"date-parts":[[2021,7,24]],"date-time":"2021-07-24T04:25:30Z","timestamp":1627100730000},"source":"Crossref","is-referenced-by-count":7,"title":["New Set of Invariant Quaternion Krawtchouk Moments for Color Image Representation and Recognition"],"prefix":"10.1142","volume":"22","author":[{"given":"Gaber","family":"Hassan","sequence":"first","affiliation":[{"name":"Department of Basic Sciences, Faculty of Engineering, Sinai University, North Sinai 45511, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khalid M.","family":"Hosny","sequence":"additional","affiliation":[{"name":"Department of Information Technology, Faculty of Computers and Informatics, Zagazig University, Zagazig 44511, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
