System and method for color deconvolution of a slide image to assist in the analysis of tissue specimen

A tissue analysis system and method for the spectral deconvolution of a RGB digital image obtained from a stained biological tissue sample, by estimating the stain component images that are obtained from a staining system configuration, where the reference stain vectors are assumed to be sampled from a known color distribution. The prior knowledge of stain variability of the staining system is adopted as initial reference stain vectors and statistical distribution of their variability. Based on the initial reference stain vectors distribution, the tissue analysis system determines both the reference stain vectors and stain component images of the input image. The image is then deconvoluted based on the reference stain vectors and stain component images.

Non-parametric transforms such as t-distributed stochastic neighbor embedding (tSNE) are used to analyze multi-parametric data such as data derived from flow cytometry or other particle analysis systems and methods. These transforms may be included for dimensionality reduction and identification of subpopulations (e.g., gating). By nature, non-parametric transforms cannot transform new observations without training a new transformation based on the entire dataset including the new observations. The features described parameterize non-parametric transforms using a neural network thereby allowing a small training dataset to be transformed using non-parametric techniques. The training dataset may then be used to generate an accurate parametric model for assessing additional events in a manner consistent with the initial events.

METHOD FOR EVALUATING AN INFRARED SIGNATURE
20220215214 · 2022-07-07 ·

A method for evaluating an infrared signature present on an object surface, which signature preferably forms a two-dimensional code. Furthermore, a monochrome or multicolour pattern, which reflects light in the visible wavelength range, can be present on the object surface. The infrared signature only absorbs light in the infrared range and can consequently be detected by means of an IR camera. In the method, an infrared light source is switched on and the infrared signature is illuminated with infrared light and an original image is recorded with an infrared camera in this state. The original image or a further-processed image based thereon is then filtered by a high-pass filter, the contrast in the image being increased indirectly or directly after the high-pass filtering. The infrared signature can finally be evaluated in the image processed in this way.
