Web16 mei 2024 · ImageJ will also perform iterative deconvolution. Bob Dougherty (OptiNav, Bellevue, WA, USA) has written two plugins: one of these generates a theoretical widefield point-spread function (PSF) based on user-provided parameters, and the other plugin uses this PSF to deconvolve a z-series image. Web13 jul. 2024 · In brief, I was going to duplicate the image, manually threshold to select only the green fluorescence, perform a watershed separation, and then analyze the particles to measure the integrated density, making sure to redirect the threshold I set to the original image. Will this help me to get the measurements that I need?
