Brightfield mask

WebNov 19, 2024 · In this protocol, we present a simple method, based on edge detection and morphological operations, that separates total area occupied by cells from the background using only brightfield channel image. The resulting segmented picture can be further used as a mask for fluorescence quantification and other analyses.

WebThe Expression Analysis application identifies cells in brightfield and creates an outline, or mask, of each individual cell (Figure 2). The fluorescence signal in one to three fluorescent channels can be then measured within the brightfield mask. This provides a label-free, non-invasive method to quantify fluorescent signals on a cell- Imaging flow cytometry enables the recognition and enumeration of subcellular areas, such as punctate spots within a cell image.
