Dominant features for content-based image retrieval usually consist of high-dimensional values. So far, many researches have been done to index such values for fast retrieval. Still, many existing indexing schemes are suffering from performance degradation due to the curse of dimensionality problem. As an alternative, heuristic algorithms have been proposed to calculate the result with `high probability'...
Aquatic plants are very important and essential inhabitants in a small or large scale ecosystem. With the increasing interest in the natural environment and the progress of IT-related technology, there has been a great demand for an aquatic plant information system supporting intuitive user interface and location-free accessibility. In this paper, we present a mobile information bank system that can...
In this paper, we propose an efficient leaf image retrieval scheme based on its shape feature. To represent leaf shape, we first derive a distance curve from each leaf using distances between its center and the points along the contour. Next, for the storage and matching purpose, we extract a set of Fourier Coefficients (FCs) from the curve. Typically, a set of FCs fails to restore the original curve...
