High-order super-resolution optical fluctuation imaging based on low-pass denoising

Abstract: A new scheme of super-resolution optical fluctuation imaging (SOFI) is proposed to broaden its application in the high-order case by separating the elimination of shot noise from the computation of cumulant, applying the low-pass denoising (LPD) operator to SOFI. The high-order cumulants are derived from a basic recursion of moments with the suppression of shot noise by the LPD on raw data. SOFI based on LPD (LPD-SOFI) demonstrates a 10.6-fold lateral resolution enhancement with the cumulant order of the 16th … Show more

“…This issue is further complicated in a real experimental setting due to fluorescence bleaching, sample drift and similar factors. Various ways for noise filtering of the raw image stack have been proposed to decrease the frame number [133] or increase the cumulant order that can be computed for a given frame number [134], but have not been widely applied yet. Data pre-processing can also be used to correct for photobleaching artifacts and as a result improve the contrast of SOFI images [135].…”

“…Besides, for weak sources and detectors with finite efficiency, the absolute values of cumulants rapidly decrease with the growth of their order n. Thus, the resolution enhancement can be also spoiled for a number of reasons mentioned in the Introduction, such as detectors imperfections and additional noise, emitters bleaching or other degradation of sources, image artefacts, etc. [6,10,16,17,[25][26][27][28][29][30][31][32].…”

“…So, quite lot of research effort was spent in attempts to retrieve potentially infinite resolution enhancement predicted for SOFI by overcoming possible practical limitations in measuring high-order correlations, such as additional noise by imperfections of set-ups, finite size of detector pixels, emitters degradation, acquired image artefacts, etc. [6,10,16,17,[25][26][27][28][29][30][31][32]. Some effort was also spent on enhancing temporal resolution, i.e., on reducing the number of raw images [10,27,33,34].…”

“…Jiang et al proposed a modified SOFI algorithm to reduce the number of raw images from hundreds to tens by improving the fluctuating signal extraction process 9 . A new SOFI scheme was proposed recently to broaden its application for high‐order cumulants by suppressing shot noise using low‐pass denoising 26 . Watanabe et al proposed a SOFI variant of Variance imaging for super resolution (VISion), which calculates the multiple orders of variance to demonstrate a remarkable 90 nm and 80 ms spatiotemporal resolution by utilizing blinking enhanced QDs 27 .…”
