Source code, display initialization with parameters (correction) |
You are initializing the display object as:
disp = Display((cam.getProperty('width'), cam.getProperty('height')))
I'm testing it with SimpleCV version 1.3.0, it raise an error:
TypeError: integer argument expected, got float
You need to parse the camera properties as Integer :
disp = Display((int(cam.getProperty('width')), int(cam.getProperty('height'))))

Annotation #3 |
In the third annotation of the Finding Blobs example in Chapter 8 it says you can change the preceding block of code to color the blobs red by adding "packs.show()". It should be "blobs.show()"
