Abstract
An image processing apparatus includes an obtaining unit, a first extraction unit, a second extraction unit, a setting unit, a filter setting unit, a generating unit, and a determination unit. The obtaining unit obtains a captured image of a test piece including a target cell having a nucleus. The first extraction unit extracts pixels which are candidates for the nucleus from pixels included in the captured image. The second extraction unit extracts a connected-pixel group which is a candidate for the target cell. The setting unit sets rectangular regions in the captured image. The filter setting unit sets a filter including regions. When the filter is disposed in each of the rectangular regions, the generating unit generates an image feature value. The determination unit determines, on the basis of whether the image feature value satisfies a condition, whether the target cell is included in the rectangular region.
