Adaptive histogram equalization in GIS
Elisabeta Antonia Haller · 2011
Abstract. In order to analyze, the aerospatial images must pass through a series of trans-formations. Interpretation can be done by a human or by a computer. Image enhancement is made for interpretation and the interpretation can be done by a human or by a computer. The color interpolation or color demosaicing technique is used to recover missing color components in a RGB color system. These techniques are classied in nonadaptive and adaptive histogram equalization algorithms. We will analyze and compare some of the nonadaptive and adaptive algorithms that are successfully used in processing of large image les, such as aerospatial images. 2010 Mathematics Subject Classication.
