Development of stereopsis technology that gives reality is an interesting research area for a long time. Stereopsis technology expresses actuality with effect of two eyes. Correct stereo matching depends on the exact estimation of image disparity that contains depth information. Wavelet transform can be applied to analyze signals in stereo vision, but related research is insufficient. In this paper,...
Absolute position detector which not only perceives the absolute position of the rotary machine but also outputs switch data according to the given angle is one of the major equipment in the field of factory automation. Absolute position detector is composed of sensor module and its controller. In this paper, a sensor controller is implemented using FPGA with VHDL. This chip has a less form factor...
In this paper, the performance analysis of the subband adaptive digital filter (SBADF) is provided, and it is shown that the SBADF provides better performance than the conventional full band adaptive digital filter (FBADF) in some applications. First, we derive the optimum filter for each subband in terms of the given input statistics, and also derive the relationship between the optimum filter for...
