Saturated,binarize,color convert im

This is my code, but i have an Error unrecognized colorconvert

Clear all close all clc

im=imread('G:\khanom hashemi\saratani\1.jpg');

figure;imshow(im)

HSV = rgb2hsv(im);

[h,s,v] = imsplit(HSV);

V=im2bw(v,.65);

r=im2bw(s,.6);

w=and(r,V);

SE = strel('disk',3);

w1=imclose(r,SE);

BW2 = imfill(w1,'holes');

SE = strel('disk',77);

BW2 =imerode(BW2,SE);

figure;imshow(BW2)

r=im(:,:,1);

r(~BW2) = 0;

g=im(:,:,2);

g(~BW2) = 0;

b=im(:,:,3);

b(~BW2) = 0;

im = cat(3,r,g,b);

saturated = Binarize[ColorConvert[im, "Grayscale"], .9]

figure;imshow(im) [L,N] = superpixels(im,500); figure

saturated = Binarize[ColorConvert[im, "Grayscale"], .9]

This is not correct MATLAB syntax. The equivalent MATLAB command is

saturated = imbinarize(rgb2gray(im), 0.9);
