IDOL OnDemand by HP offers an array of data processing APIs for format conversion, image analysis, indexing, search, and textual analysis. Preview capabilities exist to view many of these RESTful APIs behave in action. The Face Detection API scans an inputted image for faces and returns the sizing and coordinate positioning of a bounding box that surrounds any faces it detects. The API supports all standard image types (TIFF, JPEG, PNG, GIF, BMP and ICO, PBM, PGM, and PPM).
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
