乳房X光检查 - 胸肌提取方法
大家好,以下是我所面对的问题:
[url]http://imageshack.us/photo/my-images/171/tasko.png/[/url] 我的任务: 1。图像1至5我已经做了的步骤,现在我想找到的方式来获得图像6和7。 2。我需要图像6与原始图像,以获得最终的图像(图片7)。 以下是我在网上找到最简单的“胸肌提取方法”方法,有谁可以帮我转换成matlab code吗?第一至第三我已经完成,但我不是很明白第四个步骤:confused:: Algorithm: Step 1 Image4 apply local threshold i.e. convert it to binary with Threshold =173. (在第1步你可以找到image5) Step 2 Travel up to "First non-zero pixel"; Call it as POLE. Step 3 Now travel up to "First zero pixel" and replace all travelled pixels with zero. Step 4 Perform Step 1 to 3 for all rows but with following rules: a) For every POLE ,it should not exceed no. of pixel travelled by previous row b) Now if at all Rule a is violating for consecutive 5 times then decrease pole position for next row by 1 and replace all pixels with zero up to calculated POLE. 如需测试可以从这里下载原始图像: [url]http://peipa.essex.ac.uk/ipa/pix/mias/mdb041.pgm[/url] 谢谢。 |
