interactive recognition of hand-drawn circuit diagrams

After six years of study I completed my degree of BEng/MScEng (with computer science) last week. Yay! Here is a video of the final prototype:


You can download my full thesis or some slides.

Edit 2011/02/01: Here is the source code. It's a bit of a mess and it's going take a bit of work to get it going on newer systems because it probably requires an older wxWindows. The interesting parts are in src/linetools.py. If you find it useful or reference my work I'd love to hear about it.

One of my favourite opinionated parts:

It is generally believed that state coverage is superior to code coverage. It is the author's opinion, however, that state coverage is less important in Python than other languages. As Python typically processes collections (such as lists) using an iterator and not incrementing indices, there are less ways in which errors can occur. Since variables also need not be declared it is also less likely that null pointers would be dereferenced. This is, for example, one of the most frequent sources of errors in the Java programming language.
