hello everyone,
I have an image with many cathegorical objects.
I want to transform the blue objects which are "surrounded" by the orange objects of the same category as the orange objects. (only if there ara surrounded by orange objects)
Please How Can I do That ?

In your example, which of the blue obejcts would get transformed, and what does it mean to "transform" them? Do you mean you just want to change their color to orange?

in this image it would be all the light blue objects (because they are surrouded by orange object), I want to make it of the same class as the other objects (orange). so that when I count the number of objects at the end in the image it takes them into account.
Ps: I get orange object using regionprops

I want to do something like this: if the object (light blue) is surrounded by an orange object, I consider it an orange object

Define "surrounded". The upper-left blue object does not appear to touch any of the orange objects and there is a line that you can draw from the blue line (directly towards the left side of the image) that doesn't touch any of the orange objects. So why do you consider it to be surrounded?

Hi,
Objects of blue colour surrounded by the objects of orange are to be classified into orange objects
Classifying the objects using the colour, by separating the objects into different image and then combining based on the surrounding objects
A = imread('blue_orange.png');
%Obtaining the image with only orange class(which is similar to red)
B = zeros(size(A));
B(:,:,1) = A(:,:,1);
%obtaining the blue colored objects
C = zeros(size(A));
C(:,:,3) = (255/max(max(A(:,:,3))))*A(:,:,3);
%separating the object from background
[kk,kk1] = size(C(:,:,3));
D = C;
D1 = im2bw(C,0.9);
D = 255*D1;
%combining the objects
D= C+B;
%finding the maximum location of orange object
for i = 10:kk-10
for j = 10:kk1-10
if B(i,j,1) >= max(max(B(:,:,1)))
B_m = i;
B_n = j;
break;
end
end
end
%estimating the surrounding objects and assigning required value %to E variable
E = A;
for i = 6:kk-6
for j = 6:kk1-6
if C(i,j,3)==max(max(C(:,:,3)))
if sum(sum(D(i-5:i+5,j-5:j+5,1)))>=100
E(i,j,1)=A(B_m,B_n,1);
E(i,j,2)=A(B_m,B_n,2);
E(i,j,3)=A(B_m,B_n,3);
end
end
end
end
figure,imshow(E,[]);
%you can use imwrite function to save the image in folder
%imwrite(E,’output.jpg’);
Refer to Imread, imwrite and Imshow function of Matlab
