In the plate region of a vehicle image, the gray value varies frequently in cross - direction, so we define a parameter ". cross variance " to describe it. we also calculate other parameters to approximately locate the plate, they are the space length between two chars, the thickness of stroke, the peak and trough of gray value, the ratio of width and length, etc. at last, we exactly locate the plate by the theory of mathematical morphology
該方法根據圖像車牌區域橫向灰度值變化頻率比較大這一特徵提出了橫向方差參數，並結合車牌的字元間距、筆劃粗細、灰度峰谷值、長寬比值等特徵粗定位車牌，在車牌的精確定位中利用了數學形態學的方法。我們從某高速公路收費站實地拍攝的照片中選取了1000多幅作為實驗樣本數據。 -
Treat with plate grain image got by video using methods of gray level transformation, median filter, erosion, expansion and so on, gain the image which only includes grain, then detect brim of grain
對視頻採集到的板材紋理圖像進行灰度化、中值濾波去噪、二值化、腐蝕、膨脹等處理，得到僅包含目標紋理的圖像后檢測紋理邊緣。 -
The three steps included in the algorithm are license plate segmentation, which consists of rough segmentation and accurate segmentation, character segmentation and character recognition. the rough segmentation transforms the original image into a texture image, and locates the plate - like areas through the intensity of textures in these areas, and thus finds out the only true plate area according to their gray vertical projection
對車牌定位，論文研究了紋理分析和灰度垂直投影相結合的粗定位演算法，先把圖像轉換成紋理圖，利用車牌區域紋理豐富的特點找到各個類似車牌的區域，然後對這些車牌候選區域採取垂直方向的灰度投影來判別真偽車牌，獲得唯一的車牌區域。 -
This algorithm is based on the texture feature of the characters on a license plate. firstly, the long horizontal lines with small change in gray level in a car image are removed. secondly, small areas are got rid of, then an analysis of the geometric features of the connected areas and the number of inner pixels and pixels on its edge is made, and with the help of the geometric features and the projected features of car license plate, the license plate area is found out
提出了一種基於字元紋理特徵的汽車牌照自動定位演算法；該演算法結合牌照區字元的紋理特徵，首先將汽車圖像中灰度值變化平緩的長水平線去掉，之後將小的區域去除，然後對留下的連通區域的幾何特性、內部象素個數、邊緣象素個數等信息進行分析，結合牌照的幾何特徵和投影特徵，找出真正的牌照區域。
