Abstract
A technique for hiding information in an image that is based a property of the human vision system. Because of its relation to human vision properties, the technique of the present invention provides an information hiding capacity is as large as 50% of the original image data. The method includes the steps of segmenting each region of a vessel image into informative and noise-like regions by using a threshold value, arranging the data into a series of data blocks, and embedding each data block into the noise-like regions of the image.
Claims25
A method for embedding data within a vessel image having a plurality of bit planes said method comprising the steps of:
- segmenting the vessel image into a plurality of informative regions and a plurality of noise-like regions based upon at least one statistical property of said regions of the vessel image;
- arranging the data into a series of data blocks;
- embedding each data block into at least one of said plurality of noise-like regions.
A computer program product for controlling a computer for embedding data within a vessel image having a plurality of bit planes, said computer program product comprising:
- a recording medium readable by the computer;
- means recorded on said recording medium for segmenting the vessel image into a plurality of informative regions and a plurality of noise-like regions based upon at least one statistical property of each region of the vessel image;
- means recorded on said recording medium for arranging the data into a series of data blocks;
- and
- means recorded on said recording medium for embedding each data block into one of said plurality of noise-like regions.
