Very relevant. None of the recent techniques are truly revolutionary. It's all based on these same foundations. I'd say it would do good to read even older ones. There are lots of real, profitable computer vision applications built on classic methods like Hough transforms, canny edges, sift, Harris corners, etc. You should be familiar with these if you want to come across as a serious professional as opposed to a hype boy vibe coder who can just rattle off buzzwords and glue apis without fundamental understanding.
