For instance, for an 8 bit digital camera, the digitization process results in only 2 gray levels, whereas a 12 bit camera can more accurately represent the real signals using 2 gray levels, provided there are enough photons and the noise is sufficiently low.
Digital filters operate on digitized analog signals, so the digitization process is important and is critical in the system design.
For holes emanating from a surface digitization process, a hole-filling pre-processing step is needed.
The companies complaining now, if they were engaged in the digitization process we were doing, digitizing 10 million books, there would be nothing stopping them from achieving the same thing".
The second type of sampling is the intensity quantization into a range of digital gray levels, which depends on the digitization process, gain, full well depth and the readout noise of the camera.
This approach decouples our slide scanning digitization process from the viewer application and allows us to include slides digitized by a number of commercial vendor systems.
Occasionally the digitization process introduces transcription errors or other problems.
Automating the digitization process is necessary to deal with the growing amount of artifacts available.
In the next step in the digitization process, the output of the quantizer is mapped into a binary sequence.
"We're bringing history alive," said Franziska Frey, who is overseeing the digitization process and the overall project.
New techniques that will play an important role in digitization process but require further improvement are then briefly proposed.
