I'm working on detect optic disc from retinal images, by using OpenCV-python我正在使用 OpenCV-python 从视网膜图像中检测视盘
I processed image with these procedures.我用这些程序处理了图像。
1) resize the image. 1)调整图像大小。 (original size is more than 2000 x 2000)
(原始尺寸超过 2000 x 2000)
2) convert to grayscale 2)转换为灰度
3) edge detection with canny. 3)用canny进行边缘检测。
4) apply gaussianblur. 4)应用高斯模糊。
and the result is this processed_image结果是这个 processed_image
I don't know how to detect optic disc with this result.我不知道如何用这个结果检测光盘。
How can I detect optic disc with this?我怎样才能用这个检测光盘?
or Am I approached the wrong direction?还是我走错了方向?
You can try blob detection using opencv. there is a function in opencv called HoughCircles()您可以尝试使用 opencv 进行斑点检测。opencv 中有一个名为 HoughCircles() 的 function
