Generating multi-scale graphs with alpha and omega trees

[ilteralp]

Images will be segmented into superpixels with using alpha and omega trees where each superpixel is treated as a graph node. To use multi-scale cues, multiple graphs will be generated using different alpha/omega values.

This idea is from the work of Wan et al. They used edge hops to create multi-scales. At the scale s, every superpixel x_i is connected to its s-hop neighbors.
