Hi Anuradha,

As per my understanding you want to find onl the white pixels in the image of the mushroom.

As a workaround, you can try using the imerode function to remove small white patches after binarizing the image with imbinarize. The following code snippet demonstrates the use of bith these functions:

im1 = imread('mushroom.jpeg');
gray_image = rgb2gray(im1);
bw_image = imbinarize(gray_image);
se = strel('line',11,90);
erodedBW = imerode(bw_image,se);
imshow(erodedBW)

Hope this helps!
