In terms of practical application (e.g. in industry), the biggest bang for your buck is "get the illumination right". Surprised this never appears in the course (at least from glancing over the syllabus and some slides). Most CV tasks are borderline impossible if your input is acquired under uncontrollable lighting. Whereas the right illumination setup can often let you get away with nothing but a threshold binarization.
