Adaptive thresholding experiment
Hello, World!
My name is Tomohiko Koyama aka Saqoosha. I think everyone knows me as a developer of FLARToolKit. I joined JActionScripters.com too, and I hope that Japanese Flashers are exposed to the world more and more. My English is not so good. If you find a mistake, please correct me.
Recently, I researched about Thresholding algorithms. Thresholding algorithms are used to binarize and preprocess the input to find some objects within the image. FLARToolKit uses a thresholding algorithm to detect the marker.
The algorithm currently using in FLARToolKit is Global Thresholding.
Its implementation is simple and faster, but no flexibility about illumination variation. I looked for a thresholding algorithm to improve this weak point. Then found Adaptive Thresholding.
