  • Patent number: 10395091
    Abstract: An image-feature-value calculating unit extracts an image feature value of an image of a cell candidate area. An NRBC discriminating unit uses a pre-trained discriminator to identify whether or not a target cell is shown in the cell candidate area, on the basis of the image feature value of the image of the cell candidate area. When the cell candidate area is identified as an area in which a target cell is shown, a discrimination result display unit displays the image of the cell candidate area. When the cell candidate area is identified as an area in which a target cell is shown, a discriminator training unit trains the discriminator by using the image feature value of the image of the cell candidate area as a training sample on the basis of a user input about whether or not a target cell is shown in the cell candidate area.

  • Patent number: 9471977
    Abstract: There is provided an image processing device. Pixels serving as a candidate for a nucleus are extracted from pixels included in a captured image obtained by imaging a sample including a target cell having the nucleus. A connected pixel group constituted of adjacent connected pixels is extracted from the extracted pixels. A value indicating a possibility that the target cell is included within a region surrounding the connected pixel group is determined. The value indicates the possibility being determined based on a value obtained by aggregating image feature amounts expressing luminance gradients determined based on luminance distribution with respect to a blue component within different partial regions included in the region surrounding the connected pixel group without performing normalization on each partial region.
