Re: Canny edge detection and close contours

Effort vs. time? An "effort curve" rather than a "learning curve"?
So the longer you study something, the more difficult it becomes (it
takes more effort)? You have a point for some things, like perhaps
physics or engineering, where it's relatively simple as a first year
college student but then as you move along in your Ph.D. or career it
may become more difficult and the new problems you encounter become
more challenging. And the more you learn, the more you realize that
you don't know one minute fraction of one percent of what there is to
possibly know. On the other hand with things that can only take a
finite amount of learning to master the thing (e.g. a software
program, or some algorithm) I don't think effort increases. Once
you've mastered it, it's relatively easy to use from then on. On the
third hand (borrowing one of my friend's) there are some things that
may have fairly constant effort over time ( maybe you're working just
as hard now as you were 5, 10, and 15 years ago) but some things
require more effort (e.g. my constant effort at understanding a
scientific article may be less than my constant effort at learning how
to play the piano well) so in that case, effort is really the
derivative of the "amount learned" curve, i.e. effort is the slope of
the amount learned.
Semantics can be fun.

I love steep learning curves. If you plot knowledge gained on the
vertical axis by time on the horizontal axis (as time always is), then
a steep learning curve means you gain a lot of knowledge in a short
amount of time. Or did you mean it was hard to learn (flat learning
curve)?

Try plotting "effort" on the vertical axis.
