Demo of Using ImageJ on a Irregular Circle The traditional method is to measure the diameter using a ruler. However, in most cases, the center of the circle cannot be found. ImageJ can then be very helpful. You take the picture, compute its area then compute the equivalent diameter, whic...
Inone of our previous blogswe already discussed how to use ImageJ to visualize image statistics and make dark noise visible. However before analyzing the dark noise with a program like ImageJ, it is important to measure the dark noise correctly. Here are some tips on correctly measuring the d...
Digital photography and image processing allow for a novel approach to flower UV reflectance measurement that is both accessible and accurate. Location European semi‐natural grasslands. Methods We used a UV‐LED light and a mirrorless camera with a filter, which represents a low‐cost equipment ...
The investigator was blinded to the group allocation during scoring. The percentage of DNA in tail was taken as measure of the DNA damage. The median of 50 cells per each sample’s duplicate was calculated (100 comets per sample), and the average of the duplicates’ median was reported. ...
PETIOLE PRO: Leaf Analysis You can measure leaf area, check nitrogen status, measure leaf length, leaf width and other parameters of the leaf Measure More How To Measure Leaf Area With ImageJ? Probably, you’ve heard about the battle between Petiole Pro and ImageJ. However, if not – ...
To test this hypothesis, we employed a recently developed Förster resonance energy transfer (FRET) method to directly measure partitioning of WH2 domains between actin monomers and filament ends44 (Fig. 5A, Supplementary Fig. 6). To this end, we conjugated a fluorescent donor (Alexa488) to ...
Image a vertically oriented edge (or a horizontal one for the MTF measurement in the other direction) onto the detector. The vertical edge needs to be slightly tilted with respect to the columns of the sensor. The exact tilting is of no importance, it is advisable to have a tilt of minim...
To measure circularity using the bwpropfilt function, include "Circularity" when specifying the properties argument. Object Analysis: Filter properties of connected components structure and display result The bwpropfilt function can filter objects that you specify using a connected components structure. ...
with parental, A194T, L234F F. Data are means ± SE from at least three separate biological replicates for (A–E). Full size image To measure the rate of conformational change of the various F proteins, we took advantage of the ability of HPIV3 HRC-lipopeptides to capture the ...
In this example, the top panel of the Grafana dashboard uses the WsprDaemon dataset to display a simple count of the “spots” in each 10 minute time bucket with, on the second y-axis, a measure of the planetary geomagnetic disturbance index (kp) from the US Space Weather Prediction Cent...
