When we come across flowers in hills and fields, we might want to know their names. We can usually obtain information on flowers from flower picture books, but it is not available without flower names. It is difficult to search a flower from the appearance, in this study, we propose a flower information retrieval system using picture. We extract a flower area from a picture with a natural background using domain knowledge. Then we compute some features from the obtained flower area; flower color, size, the number of petals, circularity, and form similarity. We use these features as reference keys. A form similarity, which enables to retrieve visually similar flowers, is computed by matching the outline of two figures using dynamic programming. In the reference experiment, a reference ranking average is fourth and this shows our system validity.
