#12OpenCV includes face detection, and given a reasonably limited corpus of faces, it performs quite well and quite reliably.
(Whether you want to use that or use a service depends on how close to your core business this is.)

#13I'm interested in good OCR, preferably local, but I'm close to giving up and using Google Cloud Vision API --- It works well for text that's not prefectly aligned and laid out - unlike e.g. Tesseract or any other local OCR I've used.
As far as I can tell, clarifai.com doesn't have OCR, and neither does anyone else except MS and G.

#14Microsoft's CV API worked better for me.
The last time I checked WolframAlpha worked surprisingly well

#15What about Watson? http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercl...
I don't know about face recognition but I've quantatively analysed their speech recognition and it came dead last after the 5 or so others that I tested.

Hey, I made this [1]. Based on a neural net trained with generated character sets with intentional distortions and/or several font variations.
I would not recommend it for use in production, but maybe you're interested in looking at the code and customizing it to your liking. Could perhaps be combined with OpenCV.

Alternative solution for image moderation and nudity detection. Simple API and simple pricing.

#18I think it depends on your dataset and application. It should be easy enough to try both.

Pay-as-you-go, many APIs, supportive community.
For your use case you might want to check the Computer Vision tag, specifically the "Illustration Tagger" algorithm.
