where ‘f’ is an image array of data type ‘uint8’ or double. Data type ‘uint8’ restricts the values of integers between 0 and 255. It should be remembered that for a matrix of type ‘double,’ the imshow function expects the values to be between 0 and 1, where 0 is displayed as black and 1 as white.

Certain image processing commands only work with scaled double images. Finally, we can convert an intensity image into a binary image using the command im2bw(f, T), where T is a threshold in the range [0, 1]. Matlab converts f to class double, and then sets to 0 the values below T and to 1 the values above T. The result is of class logical.

The Workspace browser displays information about all the variables you create during a MATLAB session. The imread function returned the image data in the variable I, which is a 291-by-240 element array of uint8 data. MATLAB can store images as uint8, uint16, or doublearrays.

In the matlab file head.m, I tried to express what I learned about the process in the most expressive way possible. It seems that the JPEG file is broken into many blocks. Each block begins with two bytes, the first being FF in hexadecimal and the second being ‘XX’ where different ‘XX’s denoting different blocks.

The value 0 corresponds to black and 255 to white. The class uint8 only requires roughly 1/8 of the storage compared to the class double. On the other hand, many mathematical functions can only be applied to thedouble class. We will see later how to convert between double and uint8.
