I am trying to identify greenness with the help of Tuned Tri-threshold Fuzzy Intensification Operators. I tried a lot to remove white pixels which around the edges of the final image.please help me to identify clear leaf of greenness.
Function
function out = TTFIO(image, tao, zeta)
[row col]=size(image);
%% Calculating the Membership Function
img = (image - min(image(:)))./(max(image(:)) - min(image(:)));
%% Applying Intensification Operators
for j = 1:row
for k = 1:col
if img(j,k) <= tao
enhanced(j,k) = 2*img(j,k)^2;
else
enhanced(j,k) = 1-2*(1-img(j,k))^2;
end
end
end
%% Tuning the Output
out=((enhanced).^(tao+zeta));
Read Image
zeta=.5;
x=im2double(imread('corn seedling wheat straw on sunny day.jpg'));
x=imresize(x,[256 256]);
figure; imshow(x);
img1=rgb2hsv(x);
H=img1(:,:,1).*255;
S=img1(:,:,2).*255;
V=img1(:,:,3).*255;
H( (H<5) | (H>150)) = 0;
H(H>65&H<80&S>2&10&V>150) = 0;
figure,imshow(uint8(S));
% x_R=x(:,:,1); x_G=x(:,:,2); x_B=x(:,:,3);
tao_R=.9; tao_G=.8; tao_B=.5;
R=(TTFIO(H,tao_R,zeta));
G=(TTFIO(S,tao_G,zeta));
B=(TTFIO(V,tao_B,zeta));
out=cat(3,R,G,B);
t=graythresh(out);
BW=im2bw(out,t);
figure,imshow(out)
BW=bwareaopen(BW,175);
BW = imclearborder(BW);
figure;
imshow(BW)

You can look at color thresholding aproach like here, and for smothness of the edges use morphological operations. To get the best fit morpho operations in this case, may be it will take 15-30 min, but it can be done.

can you please clarify my dought
if posssble can you please give breaf explenation of TTFIO function
