Technique for Automated Recognition of Sunspots on Full-Disk Solar Images

<p/> <p>A new robust technique is presented for automated identification of sunspots on full-disk white-light (WL) solar images obtained from SOHO/MDI instrument and Ca II K1 line images from the Meudon Observatory. Edge-detection methods are applied to find sunspot candidates followed b...
