Towards a Low-Cost Mobile Subcutaneous Vein Detection Solution Using Near-Infrared Spectroscopy

Figure 4

Current result of the ongoing feasibility studies applying the proposed model to the target platform (standard mobile device). The first image shows the acquired image (converted to grayscale) using the initial version of the prototype (based on Figure 3). Subsequent images present the interim results of applying digital signal processing strategies in order to enhance and additionally visualize the vein pattern.
