FaceDetection

Runs face detection on the file(s) associated with an IDOL document FlowFile, and adds information about any detected faces to the IDOL document.

After detecting a face, the processor can run face recognition and clothing analysis. Clothing analysis returns a region containing the clothing on a person's upper body, and a region containing the clothing on a person's lower body. It also analyzes the color of the clothing in each of these regions.
