Mobile image search for tourist information using ACCC algorithm

Almost all mobile image search applications available in the market only support text queries, which it is sometimes difficult to describe the needs in text and the text input is inconvenient on small devices. This paper proposed a mobile phone image search application that can perform practical image search processing in real-time. The early stage of the project is aimed to develop the application for the tourists who can use it as a guidance tool for travelling in the country. The application can run on hundreds of different mobile phone types and platforms. In older to speed up the visual computation for searching images, the Auto Color Correlogram (ACC) and correlation (ACCC) algorithms based on Correlogram technique were developed. Applying the ACCC algorithm, it reduces the computational complexity of index construction and similarity measurement for images from O(m²d) to O(md) when compared to previous algorithm, Color correlogram.
