How do you use the Imread function in MATLAB?
A = imread( filename , fmt ) additionally specifies the format of the file with the standard file extension indicated by fmt . If imread cannot find a file with the name specified by filename , it looks for a file named filename. fmt . A = imread(___, idx ) reads the specified image or images from a multi-image file.
What is Imresize command in MATLAB?
B = imresize( A , scale ) returns image B that is scale times the size of image A . The input image A can be a grayscale, RGB, binary, or categorical image. If A has more than two dimensions, then imresize only resizes the first two dimensions. If scale is between 0 and 1, then B is smaller than A .
How do you get high quality figures in MATLAB?
To get a high-resolution image from MATLAB, you may use the “copy figure” option. In your Matlab figure, go to the “Edit” option, select “Copy Figure”, then paste it in MS word file using “crtl+v”. If you want to use the figure in latex, then save the figure in the “. eps” format.
