This work presents a revision of four different registration methods for thermal infrared and visible images captured by a camera-based prototype for the remote monitoring of diabetic foot. This prototype uses low cost and off-the-shelf available sensors in thermal infrared and visible spectra. Four different methods (Geometric Optical Translation

EMIR (Espectrografo Multiobjeto Infra-Rojo) is a wide field, near infrared, multiobject spectrograph, with image capabilities, which is currently located at one of the Nasmyth focus of the 10.4m GTC (Gran Telescopio Canarias). It allows observers to obtain many intermediate resolution spectra simultaneously, in the near IR bands: Z, J, H and K. A

The aim of this survey is the homogeneous characterization of a large sample of H II regions with active star formation in order to detect observational trends supporting the two main models of massive star formation.
