Top-hat selection transformation for infrared dim small target enhancement

摘要

To improve the performance of top-hat transformation for infrared dim small target enhancement, a top-hat selection transformation is proposed in this paper. First, the top-hat selection transformation is defined and analysed based on analysing and improving of classical top-hat transformation. Then, the top-hat selection transformation is used to enhance infrared dim small targets. The calculation of parameters used in top-hat selection transformation for infrared dim small target enhancement is discussed in detail. Various experiments verified that top-hat selection transformation was effective for infrared dim small target enhancement.
