  • Method for processing images of a living biological tissue with auto-calibration
    Patent number: 12639852
    Abstract: The invention relates to a method for imaging a living biological tissue, comprising: obtaining (S1) a plurality of successive colour images of said biological tissue, the processing method comprising a calibration phase (S2) in which at least one zonal time-dependent vector representative of the time evolution of spatial averages of intensity values of each of the colours in an area of the images is determined (S21), a bandpass filter centred on a heartbeat frequency is applied (S24), then a projection basis is determined (S26) by principal component analysis of the filtered zonal time-dependent vector, the method comprising deriving (S33) colour data representative of the time evolution of luminous intensities of the living biological tissue in the tissue images, and projecting (S35) colour data onto the projection basis.
