Working with 8-Bit and 16-Bit Images

8-Bit and 16-Bit Indexed Images Double-precision (64-bit) floating-point numbers are the default MATLAB representation for numeric data. However, to reduce memory requirements for working with images, you can store images as 8-bit or 16-bit...

Working with Images in MATLAB Graphics

What Is Image Data? The basic MATLAB data structure is the array, an ordered set of real or complex elements. An array is naturally suited to the representation of images, real-valued, ordered sets of...

Stream Line Plots of Vector Data

Wind Mapping Data The MATLAB vector data set called wind represents air currents over North America. This example uses a combination of techniques: Stream lines to trace the wind velocity Slice planes to show...

Displaying Curl with Stream Ribbons

What Stream Ribbons Can Show Stream ribbons illustrate direction of flow, similar to stream lines, but can also show rotation about the flow axis by twisting the ribbon-shaped flow line. The streamribbon function enables...

Displaying Graphics Images

Image Types and Display Methods To display a graphics file image, use either image or imagesc. For example, assuming RGB is an image, figure(‘Position’,[100 100 size(RGB,2) size(RGB,1)]); image(RGB); set(gca,’Position’,[0 0 1 1]) [warning]This image...

Matlab Annotation Objects and Example

Users typically create annotation objects from the Plot Edit toolbar or the Insert menu (select Plot Edit in the View menu to display the Plot Edit toolbar). However, you can also create annotation objects...
