Requirements: The customer wanted Elinext team to develop an application which will help users to make a picture of his or her skin, publish it online via Social Networks and have a reference guide on tan processes at hand. The mobile application had to read skin code, be capable to send to Facebook, Twitter, MySpace pictures of skin and comments to pictures.
Challenge: The main challenge for our developers was to implement skin code recognition. They faced the following difficulties:
- How to recognize where the skin is on the picture
- How to implement tan id range recognition especially for individuals with very dark skin
- How to optimize math algorithm so that it would be useful and had high performance
Solution: To solve the first task our developers had to study lots of pages of information before actually starting to develop the code. Developers investigated libraries that contain a lot of mathematical algorithms; however they decided that it will be hard for mobile devices to use such functions. They read a lot of materials about skin detection and chose one of the technologies Explicit Image Detection using YCbCr Space Color Model as Skin Detection by Jorge Alberto Marcial Basilio, Gualberto Aguilar Torres, Gabriel Sanchez Perez, L. Karina Toscano Medina , Hector M. Perez Meana from Seccion de Estudios de Posgrados e Investigacion Escuela Superior de Ingenieria Mecanica y Electrica Unidad Culhuacan Santa Ana and applied and optimized it for mobile phones.
Results: The development project outcome is an application for iPhone and iPad, Android and Android tablets, BlackBerry, Windows Phone 7 mobile platforms, available for download at app stores. The application has the following functionality:
- Make a picture
- Tan ID detection
- Sharing via Facebook, Twitter and MySpace
