In order to improve the detection performance of the main symmetry axis, a new detection method based on the clustering analysis is proposed. Some feature points are extracted from the image based on the Harris corner detection, and C-means clustering method is used to classify the feature points into C groups. Multiple random sampling is performed in each cluster to get the feature point pairs. The...
For those MHz integrated synchronous Buck DC-DC converters (ISBC), a power stage segmentation technique might be applied for the sake of improving light load efficiency. The paper discusses the difference about efficiency in the case that losses contributions from Cds and Cgd in inactive power FET subcells are considered or not and indicates the existence of efficiency optimization's saturation effect...
