SR Scheme: Spatial-match Iconic Image Representation
نویسندگان
چکیده
In order to support content-based iconic image retrieval efficiently, we propose a new spatial-match representation scheme, called SR scheme, which combines directional operators with positional operators. Therefore, our scheme can represent spatial relationships between icon objects precisely and can provide ranking for the retrieved images. In addition, we compare our scheme with the conventional 9DLT and SMR schemes in terms of retrieval effectiveness. Finally, we show from our experiments that our SR scheme holds about 7% higher recall and about 20% higher precision, compared with the 9DLT and the SMR.

Relative Spatial Distance Matrix: a Novel and Invariant Data Structure for Representation and Retrieval of Exact Match Symbolic Images
This paper proposes a new data structure called relative spatial distance (RSD) matrix, useful for the representation of symbolic images. RSD matrix is constituted by the relative spatial distances between the iconic objects in the symbolic image. A set of triplets constituted by the pair -wise relative spatial distances between iconic objects forms the surrogate representation of the symbolic ...

Due to the differences between the visible and thermal infrared images, combination of these two types of images is essential for better understanding the characteristics of targets and the environment. Thermal infrared images have most importance to distinguish targets from the background based on the radiation differences, which work well in all-weather and day/night conditions also in land s...

Due to the differences between the visible and thermal infrared images, the combination of these two types of images leads to better understanding of the characteristics of targets and the environment. Thermal infrared images are really in distinguishing targets from the background based on the radiation differences and land surface temperature (LST) calculation. However, their spatial resolu...
