Every analog voltage signal that you measure or generate must be represented in the computer as a binary value. The number of bits in this binary value depend on the specific DAQ device that you are using (12-bit, 16-bit, etc.). The number of bits determines the number of discrete ...
Most of the early information-hiding technologies are NRDH, meaning that after extracting the confidential information, there is no way to restore it to the original image, such as with the Least Significant Bit Replacement (LSB), LSB matching, modulus methods, and so on. However, scholars ...
