Recognizing Planar Objects Using Invariant Image Features
Recognizing Planar Objects Using Invariant Image Features
| Hi-index | 0.00 |
In this paper, we present novel image-derived, invariant features that accurately capture both the geometric and color properties of an imaged object. These features can distinguish between objects that have the same general appearance (e.g., different kinds of fish), in addition to the typical task of distinguishing objects from different classes (e.g. fish vs. airplanes). Furthermore, these image features are insensitive to changes in an object's appearance due to rigid-body motion, affine shape deformation, changes of parameterization, perspective distortion, viewp oint change and changes in scene illumination. The new features are readily applicable to searching large image databases for specific images. We present experimental results to demonstrate the validity of the approach, which is robust and tolerant to noise.
