2.1 Segmentation
The flowers are segmented using whorl based region merging segmentation proposed in [14]. In flowers, whorl
region is indentified using Gabor filter response and marked as foreground; and boundary is marked as background.
The flower is initially divided into regions using quick shift segmentation and later regions are merged into
foreground & background using maximal region merging. Detailed discussion of segmentation is presented in [9]
