threshold image pixel values form 800 to 1200 in matlab

To threshold image pixel values in MATLAB, you can use the logical operators to create a logical array that specifies which pixels meet your thresholding criteria. You can then convert this logical array to a binary image using the imbinarize function. Here is an example code snippet that thresholds pixel values between 800 and 1200:

main.m
% read in image
img = imread('image.jpg');

% create logical array of pixels within threshold range
thresholded = (img >= 800) & (img <= 1200);

% convert logical array to binary image
binary_img = imbinarize(thresholded);

% display thresholded image
imshow(binary_img);

This code will display a binary image where the pixels within the specified threshold range are white and all other pixels are black.
