MATLAB: Added White Frame/Background when using imread()

You can determine the x and y limits of your image by accessing the handle output of image(). Then set your axis limits to the limits of your image.

image_og = imread('image.png');
h = image(image_og);  % <----- get the output (h)
axh = gca(); 
% TUTORIAL
% h.XData are the [left, right] limits of your image
% h.YData are the [lower, upper] limits of your image however, the direction 
%    of the y axis is likely reversed so keep that in mind. 
% These limits are the centers of the corners of the image so you must add/subtract
%    1/2 from each limit value to get the true edges of the image. 
xlImage = h.XData; 
ylImage = h.YData; 
axis(axh,'equal') 
xlim(axh, xlImage + [-.5,.5])
ylim(axh, ylImage + [-.5,.5])
