Patent Images

1. An image processing apparatus comprising:

  • at least one hardware processor configured to implement;

    a setting unit configured to set an object region for detecting a target cell in each of a plurality of captured images obtained by imaging a sample including the target cell at a plurality of different focal distances;

    a calculation unit configured to calculate a Histograms of Oriented Gradients (HOG) feature quantity in each of the plurality of captured images based on a luminance gradient direction and intensity in the object region and to calculate a vector obtained by combining the calculated HOG feature quantities as an image feature quantity; and

    a determination unit configured to determine whether the target cell is included in the object region based on whether the image feature quantity satisfies conditions defined for the target cell.
