I have the binary image below which I want to use Hough Transform to detect the line in the middle. However, it cannot detect it. How can I smooth the image so the line is more easily detectable for the hough function? Thank you

在 MATLAB Online 中打开

BWImage.mat

load BWImage;

BW=(1-entropyfilt(BW,ones([11,5])));

BW=imclose(BW,ones([11,1]));

BW=bwareaopen(BW>0.2,20);

imshow(BW,[])

@Image Analyst They used radon on the binary images to get the max and min values for a background subtraction, I attached the paper here, I only followed what they instructed in pages 3-4 for the binary images, then about radon in page 5.
