Sentence examples for mean pixel value from inspiring English sources

At first, all suspicious MCs are preserved by thresholding a filtered mammogram via a wavelet filter according to the MPV (mean pixel value) of that image.

In the corresponding PET slice and three adjacent slices, a region of interest (ROI) was drawn in the liver, in which the mean pixel value and standard deviation were measured.

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.

Fluorescence intensity values of the scanned regions were digitized as 512×512 pixel images and Et or DCF fluorescence (mean pixel value) was quantified individually in all cells using the Leica Confocal software.

Regions that exceed the image boundaries are padded with the mean pixel value of the RGB training dataset.

The RGB image, with pixel values ranging between 0 and 255, is normalized by subtracting the mean pixel value.

In this study, we estimate land cover fraction at a satellite pixel scale by employing an existing 'Mean-Sensitivity Unmixing Algorithm' (MSUA), which is based on a state space defined by two key variables: (1) mean pixel values (referring to mean vegetation states), and (2) inter-annual sensitivity of pixel values to precipitation (referring to vegetation sensitivity to precipitation).

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

where f means pixel value, (t, j, i) means temporal index and position indices, and M × N means the block size.

NDVI and VOD perform better than dB in characterizing land cover variation based on mean pixel values; while dB represents more reliable and robust vegetation sensitivity to precipitation.

There was a moderate negative correlation (r2 = 0.12, P < 0.05; Pearson's Product Moment and r2 = 0.23, P < 0.05; ANCOVA) between mean pixel heterogeneity (standard deviation of mean pixel values) of the follicular wall proper (all follicles ≥5 mm in diameter) and serum concentrations of oestradiol after sponge withdrawal.
