I have been developed many parts of software for over 11 years. Major areas of my expertise include: ✅ Mobile App development (iPhone, Android, Hybrid, Unity3D, Cocos, ...) ✅ Web development (PHP, Python, NodeJS, AngularJS, Wordpress, Shopify, Laravel, AWS, Heroku) ✅ Desktop Application (C/C++, C#, Java, QT, ...) ✅ Database (Firebase, MySQL, MS SQL, Oracle, SQLite, ...) I always aim to maintain a long-term relationship with my clients. Whether you've lost your original developer, need additional resources, or want a brand new app, I can step in and take over wherever you need. For now, I am a manager of a team that has 5 full stack mobile&web developers. We guarantee clients high-quality code and fast speed. We also provide free maintenance 6 months after finishing the project. Please kindly touch us here and get success from there! Thank you for reading.

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.
