Efficient Graph-Based Image Segmentation 169 regions. Such wide variation in intensities occurs both in the ramp on the left and in the high variability re-gion on the right. Thus it is not adequate to assume that regions have nearly constant or slowly varying intensities.

Graph Based Image Segmentation Tutorial June 27, 2004, 1-5pm! CVPR 2004. Jianbo Shi, Charless Fowlkes, David Martin, Eitan Sharon. Tutorial Abstract: Image segmentation has come a long way. Using just a few simple grouping cues, one can now produce rather impressive segmentation on a large set of images.

based technique. Graph cut provides a clean, flexible formulation for image segmentation. It provides a convenient language to encode simple local segmentation cues, and a set of powerful computational mechanisms to extract global segmentation from these simple local(pairwise) pixel Computationally graph cuts can be very efficient.

Effective graph-based image segmentation strongly depends on suitable arc-weight esti-mation [11]. This module deals with interactive segmentation of natural scenes, and it will first introduce how the arc weights can be better computed from the combination of a weight based

Image segmentation strives to partition a digital image into regions of pixels with similar properties, e.g. ...

The earliest graph-based methods use flxed thresholds and local measures in computing a segmentation. The work of Zahn [19] presents a segmentation method based on the minimum spanning tree (MST) of the graph. This method has been applied both to point clustering and to image segmentation. For image segmentation the edge weights in the graph ...

The earliest graph-based methods use fixed thresholds and local measures in computing a segmen-tation. The work of Zahn (1971) presents a segmen-tation method based on the minimum spanning tree (MST) of the graph. This method has been applied both to point clustering and to image segmentation. For image segmentation the edge weights in the graph
