Installing NumPy SciPy Matplotlib on mac

It is more difficult than I have anticipated to install all these python packages. Compilation problems and obscure error messages are everywhere when I try to build and install these packages! After a few hours of googling, i found that Enthought has a ~500MB distribution of python that has all of these packages. http://www.enthought.com/products/epd.php (it is free for students!)

>>> import numpy >>> numpy.test('1','10')


>>> import scipy

>>> scipy.test('1','10')

>>> import pylab >>> x = pylab.randn(10000) >>> pylab.hist(x, 100) >>> pylab.show()

Final Report

Attached is a final report that we submitted. Although we came across a lot of unexpected problem during the past year, it was regardless a great learning experience for all of us. We were able to experiment with different technologies that are not taught in the classrooms. The report can be downloaded here. CREU Final Report

Demo Program

We decided to write a program to demonstrate how this could be used. We somehow decided that we would write a program that is sort of like the Yamaha TENORI-ON. It has a 16×16 button matrix, and the buttons that can be activated to play different notes.

Figure 1. When the program starts up, user should press “s” to enter a screen that shows the segmented image from the camera. Users then click on the color they want to the program to track. A cursor in the form of a square box will appear immediately, and it’s position on the screen will correspond to the location of the color blob.

Figure 2. Users should press “s” to exit the setup screen. The main application screen will appear, and user can select the button by moving the red cursor on the button and press “enter”.

We were experimenting with button press by moving the color finger wrap toward the screen. However, when the finger moves toward the screen, the position of the blob changes and it becomes difficult for users to select the button they originally wish to click. However, I think that it can be done, if we get to experiment with it a little more. But here is the source code for the application SequencerDemo.pdf. (Note: wordpress does not allow users to upload zip file; so I renamed it to SequencerDemo.pdf. To unzip the source code, rename it to SequencerDemo.zip)
