HP IDOL OnDemand Face Detection API

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).
