Hi All, Am working on a problem where I wish to extract regions in the image below.
Objective: - Identify every region. - Calculate the Area and related parameters.
What I have done?
  • Read image and convert to Grayscale
[MainImg, MainImg_Map] = imread('MainImg');
GrayImg = ind2gray(MainImg,MainImg_Map); #Convert to Gray
  • Detect Edges
FindEdge_Sobel = edge(GrayImg, 'sobel');
  • Create structuring element to make borders more visible
se1 = strel('line',3, 90);
se0 = strel('line',3, 0);
  • Dilate the Image objects
ImgDill = imdilate(FindEdge_Sobel ,[se1 se0]);
  • Result:

Hey Thanks, I tried that earlier. Below is the Output. Red *'s are Center of the object, measured using 'Centeroid'
Am trying to use couple of Morphological operations on the image. What do you think?
