Image processing apparatus, image processing method, and computer-readable recording medium |
摘要 |
An image processing apparatus includes a gradient magnitude calculating unit that calculates a gradient magnitude of each pixel on the basis of pixel values of a target image in which a predetermined target object is imaged; a candidate-edge detecting unit that detects contour-candidate edge positions on the basis of the gradient magnitude of each pixel; a reference-range setting unit that sets a reference range, which is to be referred to when a contour edge position is selected from among the contour-candidate edge positions, on the basis of the gradient magnitude of each pixel; and a contour-edge selecting unit that selects, as the contour edge position, one of the contour-candidate edge positions in the reference range. |
