Nose Picker

Nose Picker is the best image annotation application for iPad, iPhone, and iPod Touch. Touch screens are ideal for this type of image annotation work. The user interface has been optimized to allow fast and accurate annotation of points including full screen layouts and multitouch gestures. A "scope" tool is also available for precise point positioning. This app was originally designed to quickly locate facial features such as the eyes, nose, and mouth for biometric applications, but the app has other applications in computer vision, image processing, medical imaging, or other scientific applications. Nose Picker is designed for the 10-inch iPad screen but also supports iPhone and iPod Touch.
