2011 article

A invertible dimension reduction of curves on a manifold

Yi, N. S., Krim, H., & Norris, L. K. (2011, November 1). 2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops).

By: N. Yi n, H. Krim n  & L. Norris n

topics (OpenAlex): Advanced Vision and Imaging; Advanced Numerical Analysis Techniques; 3D Shape Modeling and Analysis
TL;DR: This paper proposes a novel lower dimensional representation of a shape sequence using a sequence of local flat subspaces adaptive to the geometry of both of the curve and the manifold it lies on and demonstrates the advantages of the proposed theoretical innovation. (via Semantic Scholar)

2009 article

A Shearlet Approach to Edge Analysis and Detection

Yi, S., Labate, D., Easley, G. R., & Krim, H. (2009, March 24). IEEE Transactions on Image Processing, Vol. 18, pp. 929–941.

By: S. Yi n, D. Labate n, G. Easley* & H. Krim n 

author keywords: Curvelets; edge detection; feature extraction; shearlets; singularities; wavelets
topics (OpenAlex): Image and Signal Denoising Methods; Advanced Image Fusion Techniques; Medical Image Segmentation Techniques
TL;DR: This paper proposes a novel approach based on the shearlet transform: a multiscale directional transform with a greater ability to localize distributed discontinuities such as edges, which is useful to design simple and effective algorithms for the detection of corners and junctions.
