This paper proposes a hair volume analysis system, which applies deep learning and image processing approaches. The proposed system is comprised of a mobile device, a Cloud Web-Service (CWS) platform, and a Cloud AI image processing (Cloud-AI) server. Furthermore, the proposed system can analyze the hair volume in a hairy scalp photo by detecting the areas of hairy pores (i.e., the hair follicle pores with hairs), and counting the number of hair shafts within these areas and evaluating the ratio of thick/thin hair shafts. The experimental results demonstrate that the proposed system can provide hair volume analysis with the accuracy of the detection of hairy pore areas reached up to 95%.
