Method and apparatus for generating hierarchical saliency images detection with selective refinement

An apparatus for generating a saliency image, the apparatus comprising:

• a size conversion unit that converts an input image into a input image of a first size and an input image of the second size and converts a first saliency image into the second size;
• a first saliency image generation unit that generates the first saliency image by applying a saliency extraction scheme to the input image of the first size;
• an area determination unit that extracts an area that satisfies a first condition from the converted first saliency image and determines an area corresponding to the extracted area from the input image of the second size;
• and
• a second saliency generation unit that generates a second saliency image by multiplying
• an image generated by applying the saliency extraction scheme to the determined area, and
• the converted first saliency image.

A non-transitory computer-readable storage medium having stored thereon computer executable instructions for performing a method comprising:

• converting an input image into an input image of the first size and an input image of the second size;
• applying a saliency extraction scheme to the input image of the first size to generate a first saliency image;
• converting the first saliency image to the second size;
• extracting an area that satisfies a first condition from the converted first saliency image;
• determining an area of the input image of the second size that corresponds to the extracted area;
• generating a second saliency image by multiplying
• an image generated by applying the saliency extraction scheme to the determined area, and
• the converted first saliency image.
