Aperio Positive Pixel Count Algorithm – Simple, Accurate Color Measurement

The Aperio Positive Pixel Count Algorithm quantifies the amount of a specific stain present in a scanned slide image, based on user specification of color. Number and intensity of pixels that fall within the parameters will be quantified, and these can be classified into intensity ranges as defined by the user.

Aperio RUO (Research Use Only) Image Analysis Algorithms have been validated by Leica Biosystems for use with .svs images from Aperio AT2, Aperio CS2, and Aperio VERSA scanners. Use of Aperio RUO Algorithms with other available scanners has not been validated, and Leica Biosystems cannot train or support customers in use of Aperio RUO Algorithms with images from these scanners.
