Considering traditional watershed segmentation has a serious over-segmentation problem and marker-based watershed segmentation has a great difficulty in marker extraction, we proposed the improved watershed segmentation with optimal scale based on ordered dither halftone and mutual information. We made some improvements on marker-based watershed segmentation. Firstly, according to vision characteristics...
There are some usual methods in vehicle license plate location, such as segmentation in grey-level image, color image edge extraction and neural networks filters etc. All these methods are proved not quite satisfactory in various conditions, or are influenced by some factors. In this paper, we present to classify colors of pixels by using improved neural networks, which include 27 nodes of input layer,...
