Weather Map Image Retrieval using Connected Color Region

In this paper, a weather map image retrieval system is proposed as an assistance for weather forecasting. The proposed retrieval system searches the past pattern of the weather map images similar to the present one. The short-term prediction on how the future pattern would occur can be derived from the retrieved past pattern. Since the weather map image categorized the weather information into several groups and differentiates them using color identification, the proposed retrieval system extracts color features from connected color regions and uses them as primitive features to retrieve the weather map images similar to a query. Then, the short-term prediction can be analyzed from the successive weather map images of the retrieved weather map images. Several experiments are conducted and the results show good retrieval performance and prediction of the proposed retrieval system.
