Digital watermarking of images

In this exercise, we will study the digital watermarking of images. The exercise is categorized in different sections where various basic watermarking techniques are introduced. A necessary prerequisite for this exercise is some basic course in digital image processing. After finishing the exercise, return by email your well-commented MATLAB functions and written report. In your report, you should describe what you have done, give answers to the predefined questions (1-8), and give some comments about the exercise. Answers to the questions can (and should) be deduced without any references. The written report should resemble more of an essay than just a discrete list of answers to the questions. Remember also to include your name(s), student number(s) and email address(es) to the report. It is recommended that the report is returned in pdf format. NOTE: All required functions (tasks 1-5) should be implemented using MATLAB as separate m-files. Input parameters for the functions are specified separately for each of the tasks, but in general, the required input images must be matrices, not names of the image files. Each of the functions must have one output parameter: the result of the current task.
