  • Process for determining the infiltration of biological cells in a biological object of interest
    Patent number: 11263781
    Abstract: The invention relates to a process for determining an infiltration profile of biological cells of interest in a biological object of interest from a digital histopathological image of biological tissues, a histological stain having previously been applied to the biological tissues, comprising generating a biological cell detection image, pixels associated with the histological stain on the histopathological image being of a predetermined color on said image, determining a distance map comprising distance iso-curves to the boundary of the biological object, and, from the distance map, calculating a curve representative of the surface density of biological cells of interest as a function of distance to the boundary, by counting, for each boundary distance value, pixels that are both of the predetermined color on the detection image and located between the iso-curve associated with said distance value and the consecutive iso-curve.
