FAQ:
How do I load the Image Processing Toolbox?
Where do you run MATLAB? If you use MATLAB on CCS account, you don't have to load the toolbox. It is already installed with the MATLAB. If you are running MATLAB on your PC, then you have to buy the Toolbox and install it.
The best way to check if Image Processing Toolbox exists, is to type "help images" in the MATLAB command line.
How do I load binary images into MATLAB?
Sample binary images are in our course image directory: /course/com3371/images. First, you have to fetch or ftp an image (as binary) to your directory. Then, use function readimage.m with the right parameters (image name, image size, and image type; you get those parameters from README file) to read an image.
Can we load the image without giving all the information (dimensions and
data type) and let the MATLAB get the info from the image header?
The function readimage.m is written for binary (raw) images. Those images do not have headers. Therefore, readimage.m requires the user to specify image size and type.
You can use command "imread" for reading images with the following formats: BMP, HDF, JPEG, PCX, TIFF, and XWD.
