TY - JOUR AU - Wielgus, Maciej AU - Patorski, Krzysztof PY - 2012/06/27 Y2 - 2024/03/29 TI - Non-local fringe image filtration: a new interferometric data filtration paradigm? JF - Photonics Letters of Poland JA - Photonics Lett. Pol. VL - 4 IS - 2 SE - Articles DO - 10.4302/photon. lett. pl.v4i2.304 UR - https://photonics.pl/PLP/index.php/letters/article/view/4-24 SP - pp. 66-68 AB - In this letter we discuss the notion of non-local filtration in the context of fringe pattern images processing, to contrast it with commonly used denoising techniques restricted to the close neighborhood of a given pixel. We evaluate the performance of the non-local means algorithm on exemplary fringe patterns to compare it with several other methods and show the filtration efficiency influence on phase calculation quality. <br /> <br />Full Text: <a class="file" href="/PLP/index.php/letters/article/view/4-24/222" target="_parent">PDF</a> <br /> <strong><br />References</strong> <br /> <ol> <li>L.
