In this paper we present a new approach for the measurement of multiple digital holograms at different positions in space that can be combined to one high resolution hologram. The reconstruction is based on a phase shifting approach, where the CCD sensor and the reference wave are moved simultaneously along different positions in x and y. An inclination of the reference wave induces a phase shift...
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) has acquired more than 1 million data with along-track stereovision. These data are processed to make digital elevation model (DEM) with orthorectified images. Using multiple DEMs obtained at different times, it is expected to enhance the spatial resolution. In this work, the methodology to enhance the resolution of DEM, especially...
Increasing pixel resolutions on displays are a current trend of consumer products. Lower resolution images can be input to these kinds of products. In this case, we have to enlarge the input images. Usually, large scale integration (LSI) and an application specified chip (ASIC) for consumer products enlarge input images by linear processes. However a linear process cannot generate a higher frequency...
