Slides are different from last year's slides.
Permission is granted to make use of the Powerpoint slideshows hereby linked from the companion website to the textbook "A Practical Introduction to Computer Vision with OpenCV" by Kenneth Dawson-Howe, Wiley, 2014, as the book is included as a recommended text in the syllabus of this course.
Projects
The description of the default project is available here.
A summary of special projects is available here.
Students tackling a special project are required to submit a full
specification to the instructor for approval.
Suggested Exercises
Language basics:
build a program that generates two matrices, prints them, sums
them, then prints the result. Fill the input matrices with random
doubles. Do the exercise in both Java and C++.
If you do not know how to generate random numbers, look at the
sample code in compilertests.tar.bz2.
OO basics: design
a class called Polygon
that handles polygons with an arbitrary number of sides. The class
should store the coordinates of all the vertices of the polygon:
the vertices are assumed to be on a plane, therefore two
coordinates are sufficient. The vertices are numbered and edges go
from vertex i to vertex i+1. The class should
provide methods to 1) get and set the number of vertices in the
polygon; 2) get and set the coordinates of the vertices; 3) get
the perimeter of the polygon. The class should also provide a
non-default constructor that receives the number of vertices when
an object is instantiated from the class. In the default
constructor you can assume that the polygon has an unmodifiable
number of sides of your choice or, if you want to tackle a
challenging exercise, you can use a data structure that allows you
to adjust the number of sides dynamically (an ArrayList
in Java, a vector
in C++). When Polygon
is complete, design a new class Triangle
derived from Polygon.
The new class should provide an additional method to get the area
of the triangle. Do the exercise in both Java and C++.
Application basics:
build a simple calculator application that operates on integer
numbers. The UI of the calculator should provide at least 16
buttons: 10 buttons for the digits from "0" to "9", 4 buttons for
the 4 basic operations ("+", "-", "×", "÷"), an "=" button to
calculate the result, and a "C" button that resets the calculator.
The UI should also provide a display that shows the numbers being
input and the results. Write your own code even
if pre-built solutions can be found online.
