Sentence examples for mean pixel area from inspiring English sources

Axon length was derived from the β-tubulin III signal and expressed as mean pixel area.

Cell body signals were deleted, and the fluorescence intensity signals for calnexin or GRP78 were expressed relative to the mean pixel area (β-tubulin III signal).

Briefly, pixels within the region of interest identified as positive based on color selection were analyzed for mean pixel density and percent of area positive (area positive/total area).

The average total pixel area and SE were then calculated.

To summarize, AC was manually cropped, and the mean pixel intensity was measured (area of AC × mean pixel intensity in that area) after subtracting the background, and the data were plotted as a percentage of fluorescence intensity.

Furthermore AUTOCAT was used to calculate the area, mean pixel value and variance of each tissue group for each animal from the three sets of images.

We quantitatively measured four features of randomly selected image objects (e.g. a single nucleus or a group of touching nuclei the latter was also considered for generality) before and after straightening: (1) size (number of voxels), (2) mean pixel intensity, (3) surface area and (4) circularity (quotient of the length of long axis against that of the short axis of an image object).

The corrected total cell fluorescence for each cell = integrated density of the cell – area of the cell × mean pixel values of three background areas.

Results were scanned on a AlphaImager (Alpha Innotech), and mean pixel intensities in equivalent areas bounding each band were background corrected and quantified with ImageJ software (NIH).

In some experiments autoradiograms were digitalized and band intensity (band volume, i.e. area x mean pixel intensity) quantified with a dedicated software (Quantity One, BIORAD).

We used Adobe Photoshop 7.0 to measure the mean pixel intensities in the brain areas of interest from at least two adjacent sections on a 256 grey scale.
