    “Wu is a very professional developer. I went to see several developers before but none can complete the job because they can't figure out the complex algorithm needed. Wu and his team work really great and really helpful and can accommodate all my requests plus some modification to the software from early drafts. I would definitely hire him again in the future. Thanks for your works guys.”

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.
