Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] 1. Algorithm description
[0032] Define two flat square structuring elements, B Mi and B Mo . Let D(B) denote the dimension of the structuring element B, ie the side length of the square structuring element. where D(B Mi )Mo ). Let B M for B Mi and B Mo The square ring edge area between, let d(B M ) is the width of the edge structure element, then B E is a flat square structural element, and D(B Mo )>D(B E ). Define flat structure element B S , where B S The size of is larger than noise and noise, but smaller than the size of the target, that is, D(B S )Mi ). B M ,B S ,B E ,B Mi ,B Mo relationship such as figure 1 shown.
[0033] There are differences between the real star point and the background noise area. The gray level of the star point area fluctuates greatly, and it is a large-sized bright spot. The noise...
