Abstract

The color detection from light emitting diode (LED) array by using smartphone camera is very difficult in visual multiple-input multiple-output (visual-MIMO) system. In this paper, we propose a method to detect the LED color through smartphone camera applying regression analysis. We apply multivariate regression model for detecting LED color. By taking picture of LED array, we detect the region of interest (ROI), then detecting LEDs by image processing algorithm, applying k means-clustering algorithm for generating possible number of colors of LED array and finally applying regression model to predict transmitted LEDs color. We get the value of test database R-squared 91.14%, 94.80% and 96.24% for red, green and blue channel, respectively.
