摘要： A method and apparatus of a device that classifies an image is described. In an exemplary embodiment, the device segments the image into a region of interest that includes information useful for classification and a background region by applying a first convolutional neural network. In addition, the device tiles the region of interest into a set of tiles. For each tile, the device extracts a feature vector of that tile by applying a second convolutional neural network, where the features of the feature vectors represent local descriptors of the tile. Furthermore, the device processes the extracted feature vectors of the set of tiles to classify the image.

摘要： This invention discloses a method and system for the segmentation and clustering of nuclei based on single-cell pathological images. The contour tracing method is used to calculate all the closed contours existing in the pathological tissue images; and optimizes the contours to obtain the segmented images of the nuclei. Then, according to the mask image corresponding to the segmented images of the nuclei, the segmented images of the nuclei are divided into individual nucleus images; the influencing features of the nuclei in the corresponding area are extracted through the mask image; through feature selection, redundant features are removed, and then the UMAP feature reduction method is used to select the two most important features for clustering the nuclei. By first segmenting and dividing the nucleus area in the pathological images, and then using the divided single nucleus for feature extraction, the basis for clustering is made more objective.

摘要： A processor for lifetime-based unmixing in fluorescence microscopy is configured to acquire an image having a plurality of pixels, each pixel providing information on photon count and photon arrival times, generate a phasor plot that is a vector space representation of the image, partition the image into image segments, evaluate the image segments according to total photon counts of the corresponding subsets of pixels, and execute a lifetime classification by selecting an image segment having a largest total photon count, determining a region of interest in the image encompassing the image segment, determining a phasor subset in the phasor plot corresponding to the region of interest, and generating a lifetime class including a set of image segments corresponding to the phasor subset. A plurality of lifetime classes is generated by iteratively executing the lifetime classification. The processor is configured to perform lifetime-based unmixing using the life-time classes.

摘要： An Enterobius vermicularis detection system is provided comprising a sample substrate, a sample disposed upon the sample substrate, and a personal computing device comprising an imaging device for acquiring one or more digital images of the sample substrate. The personal computing device may operate a digital interface allowing the acquired one or more digital images to be uploaded to one or more analysis computation servers. The one or more analysis computation servers may execute an analysis process upon the uploaded one or more digital images allowing determination of a presence of one or more Enterobius vermicularis eggs within the sample. The analysis process may output a first confidence interval value representing a likelihood of the presence of one or more Enterobius vermicularis eggs within the sample. The one or more analysis computation servers may communicate the first confidence interval value to the personal electronic device.

摘要： The invention relates to a method for producing a morphometric quantity of interest for a section of a human or animal organ on the basis of a first digital representation of a histological slide that has been subjected to a staining step that causes the pixels of said first digital representation to become different colours depending on whether said pixels describe emptiness, tissue or muscle cells. Said method especially consists in identifying pixels describing at least one polygon of interest in digital representations created from the first digital representation, in discerning, per polygon of interest, a lumen, an intima and a media of a vessel, and in producing at least one morphometric measurement of said vessel. Such a method comprises a step of producing a morphometric quantity of interest for the organ on the basis of said morphometric measurements of the identified vessels.

摘要： A method for determining a target image to be labeled includes: obtaining an original image and an autoencoder (AE) set, the original image being an image having not been labeled, the AE set including N AEs; obtaining an encoded image set corresponding to the original image by using the AE set, the encoded image set including N encoded images, the encoded images being corresponding to the AEs; obtaining the encoded image set and a segmentation result set corresponding to the original image by using an image segmentation network, the image segmentation network including M image segmentation sub-networks, and the segmentation result set including [(N+1)*M] segmentation results; determining labeling uncertainty corresponding to the original image according to the segmentation result set; and determining whether the original image is a target image according to the labeling uncertainty.

摘要： A method, and corresponding apparatus, for identifying a feature in an image comprises determining a plurality of characteristic values for each pixel or group of pixels within the image, and determining a confidence value for a target area of the image on the basis of the plurality of characteristic values of the pixels within the target area. Each of the plurality of characteristic values relates to a different characteristic of the feature. The confidence value is indicative of whether the feature is represented by the target area of the image.
