变尺寸组合窗口在声呐图象搜索定位中的应用

An Application of the Variable Window in Dimension and Compound Window in the Sonar Image Registration

根据沉底小目标声呐图象的特点 ,分析了传统的模板匹配定位方法不适用的原因 ,提出了变尺寸窗口和组合窗口的思想 ,并将其运用于沉底小目标声呐图象的搜索定位过程中 ,提出了一种变尺寸组合窗口搜索定位方法 ,通过实例证明了这种方法的可行性 .窗口是图象处理中最重要的基本概念之一 ,本文提出的变尺寸窗口和组合窗口的思想 ,是对图象处理中窗口概念的推广 .

The reasons why the image registration method of traditional template matching isn't applicable to the sonar image of a small target on the sea bed were analyzed according to its peculiarity.The thoughts on the variable window in dimension and compound window were put forward and they are used in the sonar image registration of a small target on the sea bed.An image registration method based upon the variable window in dimension and compound window were put forward and its feasibility is demonstrated by an example .The concept of window is one of the most important basic concepts in digital image processing.The thoughts on the variable window in dimension and compound window will develop the concept of window.
