Microalgal biomass quantification from the non-invasive technique of image processing through red–green–blue (RGB) analysis

نویسندگان

چکیده

Abstract Continuous monitoring of biomass concentration in microalgae cultures is essential and one the most important parameters to measure this field. This study aims at digital image processing RGB greyscale models, being a simple low-cost method for cell estimation. Images obtained from different photobioreactors with wastewater conditions cultivation Chlorella vulgaris were analyzed. The results suggested that technique very effective under controlled lighting conditions, contrast placed outdoors design, presenting lower linearity. accuracy could be improved high-quality charge-coupled device (CCD) camera. development efficient methods assess an necessary step towards large-scale cultivation. colour analysis has great potential meet needs cost-effective automated way using cheap instruments.

Detection of Coastline Using Satellite Image-Processing Technique

Extended abstract 1- Introduction  Coasts maintain their natural sustainability without human intervention and in spite of short-term changes, we are ultimately confronted with a coastal healthy environment, i.e. natural, rocky beaches, sandy beaches and so on. Today's use of remote sensing in most natural sciences is widespread. Due to the fact that fieldwork is costly and time-consuming, ...

Combining image processing technique and three artificial intelligence methods to recognize the freshness of freshwater shrimp

Since seafood is highly susceptible to corruption, it is important to check their storage and shelf-life time. In this research, image processing technology was used to recognize the freshness (time lasted of catching) of shrimps. Shrimp samples were randomly selected from shrimp farming pools and stored in three storage conditions: freezer, refrigerator, and cool environments. Images were take...

Superstructure optimization of biodiesel production from microalgal biomass

In this study, we propose a mixed integer nonlinear programming (MINLP) model for superstructure based optimization of biodiesel production from microalgal biomass. The proposed superstructure includes a number of major processing steps for the production of biodiesel from microalgal biomass, such as harvesting of microalgal biomass, pretreatments including drying and cell disruption of harvest...
