We can use imfinfo to get some basic image information. For demonstration purposes, we will be working with a small subimage (5000 by 5000). The original image from the website was 100000 by 20000 pixels. 'large_image4.jp2' and 'large_image4.tif' are based on an image taken from HiRISE (High Resolution Imaging Science Experiment). We will take a look at 2 types of files that are commonly used for large image applications: TIFF and JPEG2000. The Image Processing Toolbox contains a number of tools for dealing with large images. Images can become quite large depending on the application, such as medical applications or satellite imagery. Now, let's talk specifically about large images.

Legend( 'Original', 'Down Sampled', 'Location', 'Northwest') Here's a quick example of using interp1: % High-resolution data Here are some functions for down sampling (resampling) your data: interp1, interp1q, interpft, interp2, interp3, interpn, pchip, spline.įor image (2D), you can use interp2 or a more appropriate function imresize from the Image Processing Toolbox. Even though your variable may have over 1 million points, the area on your screen for your plot will not have that many pixels to capture all the details. When it comes to visualizing a large data set, consider down sampling the data before plotting.

In the documentation linked above (last bullet point), there are examples of using loops to read through text and binary files. These functions can be used in conjunction with for loops to step through the large data set. csvread, dlmread - delimited file reading.textscan - versatile function for reading structured ASCII files.
