Abstract
A plurality of quantization conditions for embedding additional information is held. An image is segmented into a plurality of embedding regions, and a condition used in quantization is selected from the plurality of quantization conditions based on information of the image that corresponds to an embedding region to be processed and a position of the embedding region to be processed.
Claims15
An image processing apparatus for embedding additional information in an image, comprising:
- a holding unit that holds a plurality of quantization conditions for embedding the additional information;
- and
- a selection unit that segments the image into a plurality of embedding regions, and selects a condition to use in quantization from the plurality of quantization conditions based on information of the image that corresponds to an embedding region to be processed and a position of the embedding region to be processed.
An image processing apparatus for embedding additional information in an image, comprising:
- a holding unit that holds a plurality of multiplexing periods for embedding the additional information;
- and
- a selection unit that segments the image into a plurality of embedding regions, and selects a multiplexing period to be multiplexed to the image from the plurality of multiplexing periods, based on information of the image that corresponds to an embedding region to be processed and a position of the embedding region to be processed.
An image processing method for embedding additional information in an image, comprising:
- holding a plurality of quantization conditions for embedding the additional information;
- and
- segmenting the image into a plurality of embedding regions, and selecting a condition to use in quantization from the plurality of quantization conditions based on information of the image that corresponds to an embedding region to be processed and a position of the embedding region to be processed.
