基于K-均值和区域生长计算法医损伤面积

The research of calculation of the injury area in the medical jurisprudence image

目的:法医鉴定伤者器官受伤面积或器物损伤面积时,通常采用记数坐标纸上网格数量的方法,其结果与法医的经验有关,主观性强,误差大,不利于法庭的出示和案件的侦破。方法:提出了一种基于K-均值和区域生长相结合的方法来计算损伤面积。结果:实验研究表明,该方法能有效的计算不规则区域的面积。结论:区域生长的方法计算不规则区域面积比记数坐标纸网格数量的方法具有更高的精度。

Objective： The legal medical experts usually calculate the area of injured organs in body or other injured items by counting the grids in coordination paper. The experiences of the legal medical experts determine the result of this method. The result is subjective and has serious errors. So it is not conductive to the court and case detection. Methods ： This paper proposes a method to calculate the injured area by hybrid of K-means algorithm and region growing algorithm. Results： The experiment shows this method is effective to calculate the area of irregular region. Conclusion： The result of this method is more accurate than the method of counting the grids in coordination paper.
