im2bw matlab

In MATLAB, the `im2bw` function is used to convert an image to binary format. The function takes an input grayscale or RGB image and a threshold value, and outputs a binary image where pixel values are either 0 or 1 based on whether they are below or above the threshold value.

Here's an example of how to use `im2bw`:

% Read in an image
img = imread('example.jpg');

% Convert to grayscale
gray_img = rgb2gray(img);

% Convert to binary using a threshold value of 0.5
binary_img = im2bw(gray_img, 0.5);

% Display the binary image
imshow(binary_img);

In this example, we first read in an RGB image and convert it to grayscale. We then use `im2bw` to convert the grayscale image to binary format using a threshold value of 0.5. Finally, we display the resulting binary image using `imshow`.
