Need:
Skycomp wanted to replace the need to print out 1000′s of traffic survey pictures so that “counters” could scan through the pictures and count vehicles, marking each picture with a grease pencil.
Deliverable
Sky Counter loads the images in a viewer area with marking tools to replace the grease pencil. Different types of vehicles can be marked with different symbols. The view area positions images end to end to present a filmstrip style display. All annotations are stored in a file that can be emailed back to Skycomp, enabling them to outsource the counting effort.
In building this application, I implemented the following techniques:
- File system access for loading folders of images
- Image caching for performance
- Custom zooming and panning algorithms to allow seamless functioning at a variety of zoom levels
- Annotation storage through a custom data format which allowed employees to email their tags for review and editing by supervisors
