Description: This paper presents two new 3D curvelet transforms which are built as extensions of the 2D first
generation curvelet transform. The first one, called the RidCurvelet, is especially well designed
for representing 2D surfaces in a 3D space while the second one, the BeamCurvelet, is better
adapted to represent 1D filaments in 3D space. We show that these 3D curvelet transforms can
be built using existing 3D transforms, the 3D wavelet transform, the 3D ridgelet transform,
and the 3D beamlet transform. We illustrate the applicability of these transforms on various
examples such as the detection of linear structures and planar surfaces, as well as on denoising
and inpainting. Platform: |

Description: Feature extraction is a key issue in contentbased
image retrieval (CBIR). In the past, a number of
texture features have been proposed in literature,
including statistic methods and spectral methods.
However, most of them are not able to accurately capture
the edge information which is the most important texture
feature in an image. Recent researches on multi-scale
analysis, especially the curvelet research, provide good
opportunity to extract more accurate texture feature for
image retrieval. Curvelet was originally proposed for
image denoising and has shown promising performance.
In this paper, a new image feature based on curvelet
transform has been proposed. We apply discrete curvelet
transform on texture images and compute the low order
statistics from the transformed images. Images are then
represented using the extracted texture features. Retrieval
results show, it significantly outperforms the widely used
Gabor texture feature. Platform: |
