Flexible Nasal Tip Produced by Slender Septal Extension Graft.

Septal extension grafts (SEGs) can increase projection. However, it requires a large amount of graft and can result in a frozen tip. Thus, this study introduces a modified SEG, called a partial SEG.

Unsupervised clustering approaches to color classification for color-based image code recognition.

Color-vision-based applications for mobile phones has become a subject of special interest lately. It would be interesting to investigate an unsupervised, adaptive, and fast algorithm that can classify color components into color clusters. We propose a hierarchical clustering approach using a single-linkage algorithm and a k-means clustering approach to color classification for color-based image code recognition in mobile computing environments.
