That is good stuff but no: what I am after is blog posts that are editorially aimed at drawing the reader into the subject and then making something of practical/genuine value happen. There is many tutorials presented on OpenCV's page and I'm by no means judging all of them but many of them do seem to fall into 2 discreet categories, either a) extremely simple (
http://docs.opencv.org/doc/tutorials/introduction/load_save_... ) or b) extremely complex (
http://docs.opencv.org/doc/tutorials/ml/non_linear_svms/non_... ). Neither is very exciting/accommodating for someone starting out in the field.
