Edge detection using G-lets based on matrix factorization by group representations
作者：
Highlights：
• Features of G-lets Edge Operator:
• Geometry of objects in the image are preserved.
• Edges are continuous.
• Tracking outlines of small objects in cluttered images are possible.
• Edges in noisy images without losing continuity is shown to be possible.
• Computations are light due to sparse operations.
