    Abstract: A necrotic cell region detection apparatus includes an image acquiring unit, a segmentation unit, a band separate unit, a feature value calculating unit, a luminance calculating unit, and a judging unit. The image acquiring unit acquires a cell image. The segmentation unit divides the cell image into multiple regions so that a local imaging properties. The band separate unit separates a low-band image and a high-band image. The judging unit forms a feature space composed of the texture feature value calculated by the feature value calculating unit and the luminance average value calculated by the luminance calculating unit, and judges a region formed by necrotic cell in the feature space.

    Abstract: An image processing device includes a processor configured to: set a plurality of first seed positions, pixel values of which indicate three-dimensional peaks, in a stack image of a cell; give an identification number to each first seed position; set a standard size of a cell in a predetermined direction of the stack image; set, referring to each first seed position, second seed positions within a range of the standard size centering on each first seed position, the second seed positions being positions shifted in the predetermined direction with respect to the first seed positions; give the same identification number as the identification number of the first seed position of a reference source to each second seed position; and form two-dimensional cell regions in all the first seed positions and thereafter form two-dimensional cell regions in the second seed positions.

    Abstract: An cell contour formation apparatus includes a cell image acquiring unit, a subband image creating unit, a features calculating unit, a correcting unit, a contour forming unit. The subband image creating unit creates subband images including a low frequency image and a high frequency image. The features calculating unit calculates a local texture features from the high frequency image. The correcting unit corrects the high frequency image on the basis of the pixel value of the low frequency image and the texture features. The contour forming unit forms contours of cells included in the cell group on the basis of the corrected high frequency image.

    Abstract: A cell division tracking apparatus includes a control unit, a search range setting unit, a daughter cell judgment unit. The control unit tracks division processes of the cells based on a cell image group composed of the cell images. The search range setting unit sets a search range to search for daughter cell regions corresponding to daughter cells resulting from a division of a mother cell based on the mother cell region detected by the mother cell detection unit. The daughter cell judgment unit judges whether the cell regions are the daughter cell regions based on a region in which regions of the cell overlap the search range regarding the cell images collected at and after a detection of the mother cell region.
