DIAZ, Carolina S  and  BARON, Jorge H. Development of a biomass sensor prototype based in image processing algorithms. Rev. cienc. tecnol. [online]. 2017, n.27, pp.58-62. ISSN 1851-7587.

The initial concerns of a new biomass prototype portable sensor, using digital image processing are shown in this paper. It is based on the color variation that is observed during the cultivation of the microalgae culture. This color differentiation is mainly due to the variation in the composition of the culture, as microalgae grow and capture solar energy; this is directly related to the growth and production of microalgae biomass. The color variation is evaluated using three primary colors (red, green and blue) using an algorithm based on the RGB model. This algorithm seeks to extract the variables which determine the characteristics of the culture. This allows establishing the basis and the development of a biomass sensor prototype that allows estimating the production of biomass and the different phases of culture based on vision.
