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.
Claims20
A computer-implemented method of detecting a foreign object on a background object in a sample image, comprising:
- 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;
- wherein segmenting the salient region is performed by an automatic Grabcut operation without user interaction.
An apparatus for detecting a foreign object on a background object in a sample image, comprising:
- a memory;
- and
- one or more processors;
- wherein the memory and the one or more processors are connected with each other;
- and
- the memory stores computer-executable instructions for controlling the one or more processors to:
- extract image features of the sample image;
- detect a salient region in the sample image;
- and
- segment the salient region to determine a contour of a foreign object region based on results of segmenting the salient region;
- wherein segmenting the salient region is performed by an automatic Grabcut operation without user interaction.
A computer-program product comprising a non-transitory tangible computer-readable medium having computer-readable instructions thereon, the computer-readable instructions being executable by a processor to cause the processor to perform:
- extracting image features of a 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;
- wherein segmenting the salient region is performed by an automatic Grabcut operation without user interaction.
