CS technology information hiding algorithm based on capacity of image block

摘要

For compressed sensing technology used in the field of information hiding, the traditional algorithm is to measure the entire carrier (large redundancy - the entire carrier of the measured value) to hide. The calculation time is long and the stego image imperceptibility can be further improved. In this paper, first according to the number of secret information block the carrier and the complexity of vector selection and information hiding based on measurement, experiments show that this algorithm improves the imperceptibility and saves the computing resources. The effect is ideal.
