In this paper an image correlation algorithm is implemented on FPGA architecture for assisted movements of visually impaired persons or automotive driving systems. Taking into account the limitations of FPGA devices and the special requirements of the correlation based image matching algorithm a semi-parallel approach is proposed. This provides an optimal tradeoff between area and speed of the implemented...
A concept of Cellular Neural Networks with dynamic cell activity control is proposed in the paper. The concept is an extension to the Fixed State Map mechanism and it assumes that cells can be disabled or enabled for processing based on assessment of current distributions of their neighboring signals. A particular case, where this assessment is made by thresholding a result of cross-correlation between...
