Adaptation of Image Processing technique in identification of earthquake induced anomalous feature from TEC: A new Approach

The basic aim of the paper is to adopt image processing approach for extraction of pre-seismic features from global Total Electron Content (TEC) data with an aim of identification of impending earthquake (EQ).For this purpose an algorithm is developed using ‘Color Histogram based Search and Retrieve Technology' in matlab environment where pixel information of the global TEC images are extracted.The conversion of these pixel information into coded form and translation of these cipher symbol into TEC magnitude are discussed in details in the paper.The final result is the comparison of anomalous symbolic pattern with reference toEQ time Equatorial Anomaly and thosereceived in regular environment to identify an impending EQ.The technique is tested in two events and the reliability is assessed through real observation.
