tophat
解釋
大禮帽-
It gives assistance to improve efficiency of the multiple frames accumulation. by analyzing the merits and demerits of several kinds of preprocessing, such as highpass filtering, median filtering, tophat transformation in mathematical morphology and wiener filtering, the local singularity filtering based on improved susan principle has been given, and it has a high power to raise the probability of target detection in single frame
良好的預處理將提高后續的多幀積累的效率，對比常用的幾種預處理演算法，如高通濾波、中值濾波、數學形態學的tophat濾波、維納濾波等方法的優點和不足，提出了一種改進的susan濾波器? ?區域奇異性濾波，該濾波方法對于提高單幀檢測概率有很好的功效。 -
