Abstract
The world are facing threats due to the spread of bacteria and viruses. Thus, a lot of researches are continuously exploring the topic of contaminants. One of the most significant ways to kill the contaminants are by sanitizing. Unfortunately, there is a lack of methods in detecting the contaminants for the sanitization to be performed efficiently. In this paper, we proposed the approach of detecting biological stains using the combination of HSV color segmentation, UVA light and also blue bandpass filter. Using color segmentation with the aid from UVA light, the fluorescent image of detected stains can be extracted. In addition, the blue bandpass filter can filter out the presence of background noises in order to increase the accuracy of the detection. A simple experiment was conducted in order to validate the developed algorithm.
