Abstract:
A computer-implemented method of detecting a foreign object on a background object in a sample image is provided. The computer-implemented method includes extracting image features of the sample image; detecting a salient region in the sample image; and segmenting the salient region to determine a contour of a foreign object region based on results of segmenting the salient region. Segmenting the salient region is performed by an automatic Grabcut operation without user interaction.
