I have taken a photograph and got the ROI based on the color of the skin.Now i want to seperate the ROI from the rest of the portion.

What does that mean? You already have an ROI so I assume that is a binary image of which pixels are skin and which are not. What else more do you need? What are the two things you will have after you do this undefined "separation"?

% 1_0 -> efecto de "loncheado" vertical, parece que faltasen cortes % 1_1 -> scan vertical en 2 tramos inconexos, "loncheado" % 1_2 -> no es 3D, son 2 cortes sueltos % 1_3 -> orientación "tumbado" % 2_0 -> OK, 47 cortes eje axial % 2_1 -> OK, 29 cortes eje axial % 2_2 -> OK, 201 cortes eje axial % 2_3 -> OK, 47 cortes eje axial % 2_4 -> OK, 201 cortes eje axial % 2_5 -> no es 3D, un solo corte % 2_6 -> orientación "tumbado", con proyección incluida
load 'TAC-Nasal-MATLAB\TAC_Nasal_2_2' v = volume(1:2:end,1:2:end,1:1:end); close all, figure(1) p = patch(isosurface(v, 700)); %isonormals(v, p) set(p, 'FaceColor', 'red', 'EdgeColor', 'none'); daspect([1 1 size(v,3)/size(v,1)*1.5]) view(3) camlight; lighting phong
figure(2), v2=zeros(size(v,1),size(v,2),1,size(v,3)); v2(:,:,1,:)=v; v2=(v2-min(v2(:)))/(max(v2(:))-min(v2(:))); montage(v2), set(gcf,'Name',[num2str(size(v,3)) ' cortes verticales'])
