I have an image from which I want to extract a region and display it in a separate image . I have written a code but it's displaying an error message.
Below is my code:
I = imread('Intensity1.jpg');
hold on
mask = false(size(I));
mask(200:400) = true;
I want to extract the region from 200:400(i.e. only the yellow and green part of the image) and display them separately . But I am shown the following error message:
Error using visboundaries
Expected input number 1, BW, to be two-dimensional.
Error in visboundaries>obtainAndValidateBoundaries (line 236)
validateattributes(B, {'numeric','logical'}, {'2d','real','nonsparse'}, ...
Error in visboundaries>parseInputs (line 185)
boundaries = obtainAndValidateBoundaries(B,first_string);
Error in visboundaries (line 91)
[ax, boundaries, options] = parseInputs(varargin{:});
Error in I2 (line 7)

Try this
hFig = figure;
subplot(1, 2, 1);
rgbImage = imread('Intensity1.jpg');
subplot(1, 2, 2);
croppedImage = rgbImage(200 : 400, :, :);
