Abstract
A method and apparatus for detecting a reflection are provided. The method includes acquiring an input image of an object, based on an activation of an infrared light source, acquiring a reference image of the object, based on a deactivation of the infrared light source, and extracting a reflection region from the input image, based on the input image and the reference image.
Claims20
A method of detecting a reflection, the method being performed by an apparatus for detecting the reflection, and the method comprising:
- acquiring an input image of an object, based on an activation of an infrared light source;
- acquiring a reference image of the object, based on a deactivation of the infrared light source;
- and
- extracting a reflection region from the input image, based on the input image and the reference image.
An apparatus for detecting a reflection, the apparatus comprising:
- an image acquirer configured to:
- acquire an input image of an object, based on an activation of an infrared light source;
- and
- acquire a reference image of the object, based on a deactivation of the infrared light source;
- and
- a processor configured to extract a reflection region from the input image, based on the input image and the reference image.
A method of detecting a reflection, the method being performed by an apparatus for detecting the reflection, and the method comprising:
- acquiring an input image of an object, based on an activation of an infrared light source;
- acquiring a reference image of the object, based on a deactivation of the infrared light source;
- generating a difference map by subtracting first pixel values of the reference image from second pixel values of the input image respectively corresponding to the first pixel values;
- determining elements of the difference map, the elements having difference values exceeding a threshold;
- and
- removing a reflection region from the input image, the reflection region corresponding to the elements.
