Abstract : Geo-referenced data are required in many GIS (Geographic Information System) applications, and maps are one of those sources. Meteorological maps are color-coded with different regions corresponding to different values of a parameter, parsing the image in order to convert into data is not very hard. A challenging problem is created due to text and different planimetric elements which are overlaid on the regions in the map when converting accurate image into data, as it is not possible to exactly replace what was under the text if icons or text i.e. the need for inpainting. Our proposal uses a probabilistic technique. It uses the probability of occurrence of colors presented in the map along with occurrence of those colors in the spatial neighboring area of the pixel (corresponding to text) whose color is required to be replaced. Simulated data is used for testing the limits of our proposed technique and results are compared with a popular image editing tool using public domain data with promising result.
