The filter has 0.1 dB maximum pass band ripple as imposed by ITU video anti-aliasing filter standard.
To avoid an unmanageable number of hotspots, smoothing with a Gaussian filter (standard deviation 2 mm) was performed before defining the hotspots.
The image is blurred with a wide Gaussian filter (standard deviation σ = 22 pixels).
Texture filters, which can be used for this are e.g. an entropy filter, standard deviation filter or range filter that quantify, as their name suggests, the entropy, standard deviation and range of values within a certain window.
However, existing expert based identification algorithms often suffer in a low recall rate and could miss a large number of valuable samples under conservative filtering standards.
Of the total reads, 535.9 million passed purity filtering standards, and, of those, 462.9 million (~86-87 ~86-87uely mapped to the sorghum genome.
Mainly, we considered Kalman-type filters, standard PF, and a recently proposed CRPF, which reduces considerably model assumptions on noise distributions.
All data sets were reconstructed using TOF with point spread function (PSF) and 3 iterations, 16 subsets, and a 5-mm post-filter, standard normalized z axis filtering, in a 256 × 256 matrix (voxel dimensions of 2.73 × 2.73 × 2.79).
Cover slips containing non-confluent cells were placed into a perfusion chamber at 28°C in sterile filtered standard aCSF.
Puncta were determined by using a local ratio of the fluorescence image filtered with Gaussian filters (standard deviations of 3.5 and 6.5 pixels) and a ratio threshold of 1.65.
