Adaptive Detection of Single-Color Marker with WebGL

Original language description

This paper presents a method for real-time single-color marker detection. The algorithm is based on our previous work, and the goal of this paper is to investigate and test possible enhancements that can be done, namely color weighting, hue calculation, and modified versions of dilatation and erosion operations. The paper also explains a solution for dynamic color selection, which makes the system more robust to varying lighting conditions by detecting the color hue, saturation, and value under the current conditions. The designed methods are implemented in WebGL, which allows running the developed application on any platform with any operating system, given WebGL is supported by the web browser. Testing of all described and implemented improvements was conducted, and it revealed that using hue weighting has a good effect on the resulting detection. On the other hand, dynamic thresholding of saturation and value components of the HSV color model does not give good results. Therefore, testing for finding the right threshold for these components had to be done. The erosion operation improves the detection significantly while dilatation does not have almost any impact on the result.
