Figure 1
Full data set statistics. (a) Typical micrograph (the average of a seven-frame movie; coarsened to a size of 512 × 512) of the diluted worm-haemoglobin haemolymph. The images contain concentrated particles as well as some `junk'. Histograms of the average density (b) and the standard deviation (c) of all of the frames in the data set (36 645 frames or a total of 5235 movies). Images falling within the standard-deviation range marked in red were used for characterization of the camera properties.
