bComparisons of median histoscores or strong pixel counts (SPCs, shown in thousands), Mann-Whitney Test.
The strong pixel count (SPC), defined as the number of pixels of 175-220 intensity, was measured per tissue core, and SPC values for replicate cores were averaged.
TPD52: tumor protein D52; MARVEL: MAL and related proteins for vesicle trafficking and membrane link; RT-PCR: reverse transcription-polymerase chain reaction; SPC: strong pixel count; FIGO: International Federation of Gynaecology and Obstetrics; NS: not statistically significant; HR: hazard ration; CI: confidence interval.

Finally, the algorithm performs edge linking by incorporating the weak pixels that are 8-connected to the strong pixels.
In this article, we propose another original approach for spatial segmentation of IMS data with strong pixel-to-pixel variability.
Our image analysis algorithm resulted in strong pixel-level agreements averaging κ=0.811 with two expert pathologists, falling only a little short of pathologist agreement (κ=0.908).
Application to other hyper-spectral or multi-channel data: the proposed methods can be applied to other IMS modalities, especially those with with strong pixel-to-pixel variability (e.g. MALDI ion source, SIMS).
This function aims to enhance the low intensity pixels while preserving the stronger pixels as defined by y tanh ( x, y ) = T [ I in ( x, y ) ] = tanh I in ( x, y ) m - 1 ( x, y ), (11).
Ridge pixels with values between T1 and T2 are weak edge pixels, and those with values larger than T2 are strong edge pixels.
