Hi. I am trying to segment the prostate from TRUS image. This is what I have so far (see attachment). Does anyone know how to :
- remove the unrelated object (ie. the white curve on top of prostate in last figure)
- outline/connect the white pixel to form the prostate boundary?
This is the code:
clc;clear;close all;i=imread('trus1.jpg');i=im2uint8(rgb2gray(i));[m,n]=size(i);I=imresize(i,[2*m,2*n]);figure, imshow(I), title('original image');[~, threshold] = edge(I, 'sobel');fudgeFactor = .5;BWs = edge(I,'sobel', threshold * fudgeFactor);figure, imshow(BWs), title('binary gradient mask');se90 = strel('line', 3, 90);se0 = strel('line', 3, 0);BWsdil = imdilate(BWs, [se90 se0]);figure, imshow(BWsdil), title('dilated gradient mask');BWdfill = imfill(BWsdil,'holes');figure, imshow(BWdfill);title('binary image with filled holes');BWnobord = imclearborder(BWdfill,6);figure, imshow(BWnobord), title('cleared border image');
