Abstract

Improved systems and methods for the analysis of digital images are provided. More particularly, the present disclosure provides for improved systems and methods for the analysis of digital images of biological tissue samples. Exemplary embodiments provide for: i) segmenting, ii) grouping, and iii) quantifying molecular protein profiles of individual cells in terms of sub cellular compartments (nuclei, membrane, and cytoplasm). The systems and methods of the present disclosure advantageously perform tissue segmentation at the sub-cellular level to facilitate analyzing, grouping and quantifying protein expression profiles of tissue in tissue sections globally and / or locally. Performing local-global tissue analysis and protein quantification advantageously enables correlation of spatial and molecular configuration of cells with molecular information of different types of cancer.

Description

field of invention [0001] Embodiments relate generally to the analysis of digital images, and more particularly, to the analysis of digital images of biological tissue samples. Background of the invention [0002] In general, the term demarcation refers to the identification of the boundaries of biological units, such as cells, within a digital image. These boundaries separate individual units from each other. Digital images can be obtained using a microscope. Weak or data-driven segmentation algorithms can be used to define cell boundaries. For example, watershed transformation is an image processing technique that has been used to segment images of cells. Using the watershed transform, digital images can be modeled as three-dimensional topological surfaces, where the values ​​(eg, brightness or gray level) of pixels in the image represent geographic heights. [0003] However, due to histological variations across different tissue types, weak segmentation algorithms ma...
