We’ve previously covered how to work with OpenCV to detect shapes in images, but today we’re taking it to a new level by introducing DLib, and abstracting face features from an image.

Label-free detection of marker proteins has also been investigated using SPR 9,10,45,46 with sensitivity limits of ∼ 10–100 pg/ml, and microcantilevers 15, with a detection limit of 0.2 ng/ml.
