Since the first-ever Mechanical Turk meet-up a year ago, there has been an explosion in crowdsourcing services. Fortunately specialization is already occurring, so for particular tasks there are companies
out there ready to provide high-quality service.
Helsinki (and SF) based Microtask, founded by Computer Graphics (CG) and Computer Vision (CV) veterans, has chosen to focus in a few areas where CG and CV are relevant. Aside from speech transcription, they currently provide form-processing (digitizing hand-written forms) and archive digitization services, and have plans to expand into image categorization and video indexing in the near future.
