摘要： Aspects of the present invention disclose a method, computer program product, and system for improving object detection in high-resolution images at inference time. The method includes one or more processors receiving a high-resolution image. The method further includes one or more processors decomposing the received image into hierarchically organized layers of images. Each layer comprises at least one image tile of the received image. Each of the image tiles have a corresponding resolution suitable to a baseline image recognition algorithm. The method further includes one or more processors applying the baseline algorithm to each of the image tiles of each layer. The method further includes one or more processors performing a result aggregation of results of the baseline algorithm applications to the image tiles of the layers.

摘要： Method of recognising an object, defect or artefact in a high-resolution image 202 (i.e. an image with resolution much bigger than a working resolution 204 of an image recognition algorithm) comprising: down sampling the high-resolution image into a series of reduced resolution layers 206-210; tiling each down sampled image, each tile having the same resolution as that of the image recognition algorithm; applying the image recognition algorithm to each tile of each layer 212-216; and aggregating the results of the application of the image recognition algorithm to each tile. Overlapping tiles in which an object is detected may be merged (Fig.5). Aggregating the results may comprise: extracting polygons of a shape of a recognized object for each layer; and mapping local polygon coordinates to global coordinates in the image having the highest resolution, thereby allowing comparison between layers of differing resolution. Aggregating the results may comprise: comparing each adjacent layer through the use of a logical “AND” (e.g. 408-410, Fig.4); and combining the comparison of each neighbouring layer through a logical “OR” (418, Fig.4). The baseline algorithm may be a pre-trained neural network model, such as a mask R-CNN (Region Based Convolutional Neural Network) or fast R-CNN.

摘要： Systems and methods for performing quantitative histopathology analysis for determining tissue potency are disclosed. According to some embodiments, a method training a tissue classifier is provided. According to the method, training the tissue classifier includes generating feature fingerprints of detected nuclei within slide images in a control library and clustering the slide images based on their corresponding feature fingerprints. According to some embodiments, a method for utilizing the trained tissue classifier is provided. According to the method, the trained tissue classifier determines whether tissue in an unknown slide image corresponds to slide images clustered during the training of the tissue classifier.

摘要： Method of creating a colour barcode, comprising: generating a histogram 218 from an image 215 of an environment; determining the most prevalent colours associated with the environment from the histogram by mapping the most prevalent colours to a first colour-space 224 and converting the colour-space to a second colour-space 228; determining, in the second colour-space, coordinates a1-a4 of the most prevalent plurality of colours and therefrom coordinates b1-b4 of a related plurality of colours; and generating a colour matrix barcode using the related plurality of colours. The related colours may include colours absent or least prevalent in the environment. Additional colours, located between the most prevalent colours and related colours may be determined and used in the matrix barcode. The first colourspace may be the red-green-blue (RGB) colour space. The second colour-space may have a luminance channel Y (e.g. HSV). The luminance channel may be removed from the second colour-space 228’ before the colour coordinate are obtained. The coordinates of the related colours may be maximally opposite the most prevalent colours. The colour barcode may have at least three colour channels (Fig. 6A).

摘要： A method of generating a coloured barcode, comprising: generating a histogram 218 from an image of an environment 215; determining a most prevalent plurality of colours in the environment by mapping the histogram of colours onto a first colourspace 224 and converting the colour-space to a second colourspace 228; determining second colourspace coordinates for each most prevalent colours a1-a4 and corresponding coordinates of a related plurality of colours b1-b4; and generating a matrix barcode using the related plurality of colours and an ultraviolet layer (Fig. 6). The first colour space may be red-green-blue (RGB) colourspace. The second colour space may be one with a luminance channel Y (e.g. HSV). The luminance channel may be removed 228’ before generating colour coordinates. The related plurality of colours may include colours absent or not prevalent in the environment i.e. maximally opposite coordinates to the most prevalent colours. Additional colours, between the most and least prevalent colours, may be determined and incorporated into the barcode. The ultraviolet layer may be a top layer of the barcode.
