Chance Software Developer 

Thank you for considering my profile. I have have been developing iOS & Android apps over 5 years. I can help you develop iOS , Android apps, Backend apis. My another major skill is web and mobile GIS application implementation. Most of my clients have been satisfied our job results. Here is one of reviews from my clients. - “Excellent developer. Fast, responsive and super impressive results” - I've started my professional experience as C/C++ developer in 2005. During the 4 years I developed a low-level system software for Windows/Linux platforms. In early 2009 I've set my eyes onto Apple devices and started developing mobile software. And I am working in GIS apps with a great GIS expert who has 10 years experiences. I am crazy in code quality - it makes me happy when I feel I do a perfect job. Also some of my personal projects I've shared to open source community. I can lead many developers for the project too. Looking forward to working with you and good luck with your project.

A new edge detection algorithm for flame image processing

Digital image processing is playing an increasingly important part in imaging based flame monitoring systems. A crucial step in flame image processing is to detect the flame edge, a dividing boundary between the area where there is thermo- chemical reaction and those without. The determination of flame edges is a precursor to flame image processing and measurement of flame parameters. Several known edge detection methods have been tested to identify flame edges but the results achieved are disappointing.
