Weed Identification Using Imaging Technology and Spectroscopy

Weed Infestation Identification Using Hierarchical Crowdsourcing

Weed infestation is a common problem in agriculture that adversely affects crop production. Given severe constraints on the budget of many landgrant universities due to the economic downturn, outreach services have taken a hit. To adapt to current economic climate without adversely affecting the quality of outreach program for weed management, we present a hierarchical system that uses image ca...

Identification and characterization of pigmented photoreceptor-producing microorganisms using FTIR spectroscopy

The identification, differentiation and classification of microorganisms have been subjects of research for many years. Recently, Fourier transform infrared (FTIR) spectroscopy techniques have gained attention in the characterization and classification of microorganisms based on biochemical profiles and cell structure characteristics. In the present study, the characterization and differentiati...

Precision and automation weed control technology

Automatic Identification of Weed Seeds

We explore the feasibility of implementing fast and reliable computer-based systems for the automatic identification of weed seeds from color and black and white images. Seeds size, shape, color and texture characteristics are obtained by standard image-processing techniques, and their discriminating power as classification features is assessed. These investigations are performed on a database ...

Thermal Imaging Spectroscopy: Present Technology and Future Dual Use Applications

Rapid advances in hyperspectral technologies have led to new sensors, which greatly improve our ability to gather information about distant objects without direct physical contact. While many of these sensors and technologies were designed for environmental monitoring and earth science, they may have important uses for security application and humanitarian aid missions. As the number and capabi...
