Abstract
A method, apparatus, and medium of generating a visual attention map. A visual attention map to extract visual attention may be generated to convert a two-dimensional (2D) image into a three-dimensional (3D) image based on visual attention. The 2D image may be downscaled and at least one downscaled image may be generated. A feature map may be extracted from the 2D image and the at least one downscaled image, and the visual attention map may be generated.
Claims19
An apparatus of generating a visual attention map, the apparatus comprising:
- a downscaling unit to downscale a two-dimensional (2D) image and to generate at least one downscaled image;
- a feature map generation unit to extract feature information from the 2D image and the at least one downscaled image, and to generate at least one feature map;
- and
- an attention computation unit to perform low-level attention computation using the at least one feature map, and to generate the visual attention map based on a result of the low-level attention computation.
An apparatus of generating a visual attention map, the apparatus comprising:
- a block division unit to divide a 2D image into a plurality of blocks;
- an area setting unit to select at least one block of the plurality of blocks as a center area, and to select at least one block from a surround area adjacent to the center area as a surround block;
- a feature information extraction unit to extract first feature information of the center area and second feature information of the surround area;
- and
- a histogram computation unit to compute a histogram distance between the first feature information and the second feature information, and to generate the visual attention map.
A method of generating a visual attention map, the method comprising:
- downscaling a 2D image and generating at least one downscaled image;
- extracting feature information from the 2D image and the at least one downscaled image, and generating at least one feature map;
- and
- performing low-level attention computation using the at least one feature map, and generating the visual attention map based on a result of the low-level attention computation.
A computer-readable recording medium storing a program causing at least one processing element to implement a method of generating a visual attention map, the method comprising:
- downscaling a 2D image and generating at least one downscaled image;
- extracting feature information from the 2D image and the at least one downscaled image, and generating at least one feature map;
- and
- performing low-level attention computation using the at least one feature map, and generating the visual attention map based on a result of the low-level attention computation.
