We present our pipeline to reveal the old stellar flux at 3.6$\\mu m$ and obtain stellar mass maps for more than 1600 galaxies available from the Spitzer Survey of Stellar Structure in Galaxies (S$^{4}$G). This survey consists of images in two infrared bands (3.6 and 4.5$\\mu m$), and we use the Independent Component Analysis (ICA) method presented in Meidt et al.
