This paper presents an approach called linear probe search to locate and segment license plate , which makes use of the characteristic of the license plate using a linear structure to scan the image and record the marching pixels 该算法充分利用车牌固有特征采用线段型结构元素逐行扫描图像,统计与之匹配的结构象素点进行分析,能准确而快速地检出车牌区域。
Linear probing is a scheme in computer programming for resolving hash collisions of values of hash functions by sequentially searching the hash table for a free location. This is accomplished using two values - one as a starting value and one as an interval between successive values in modular arithmetic.
