This MATLAB function returns a binary image BW containing 1s where the function finds edges in the grayscale or binary image I and 0s elsewhere.
If you have never worked with MatLab before, the syntax may be a bit confusing but worry not, it isn't that difficult. Below, you can see the function for converting an RGB image to grayscale. function returnedImage = toGrayscale(image) i = image; R = i(:, :, 1); G = i(:,...
RGB—Truecolor image m-by-n-by-3 numeric array Truecolor image, specified as anm-by-n-by-3 numeric array. Thergb2grayfunction expects truecolor images of data typedoubleandsingleto have values in the range [0, 1]. If an image has values outside the range [0, 1], then you can res...

This MATLAB function creates a binary image from 2-D or 3-D grayscale image I by replacing all values above a globally determined threshold with 1s and setting all other values to 0s.
Open in MATLAB Online I have created an grayscale image: A=repmat(-100:100,100,1); figure(1) imshow(A,[]) I save this image to a file using IMWRITE as a 16bit image and it becomes black and white: imwrite(A,'myimage.png','BitDepth',16) ...

Here's an example using thecameraman.tifimage that's part of the image processing toolbox. This is what it looks like: So we can load in that image in MATLAB like so: imageArray= imread('cameraman.tif'); Next, we can use the above image, generate a HSV colour map then pseudocolour...
