Hardware emulators are software implementations of (past) computer architectures to reproduce original environments for a wide range of purposes. Most emulators and virtual machines are programmed for local access, which means that they are installed on the machine the user is working on. The screen output gets redirected into a window or the whole screen […]

Automated identification of corresponding images and duplicate removal is a challenging task due to inconsistent quality of digitized book collections. Validating such collections based on qualitative criteria is a challenging endeavor according to the sheer amount of data that has to be processed. Traditional approaches seem to have peaked at a certain level. Scientists at […]
