Functional-structural modeling and high-throughput phenomics demand tools for 3D measurements of plants. In this work, structure from motion is employed to estimate the position of a hand-held camera, moving around plants, and to recover a sparse 3D point cloud sampling the plants’ surfaces. Multiple-view stereo is employed to extend the sparse model to a(More)
Avian pathogenic Escherichia coli (APEC) infections are responsible for significant losses in the poultry industry worldwide. The disease might present as different local infections or as septicemia. Here, we present the draft genome sequences of three Brazilian APEC strains isolated from different kinds of infections. The availability of these APEC genome(More)
This poster describes a technique for reconstructing tomographic images generated by a minitomograph scanner for soil science developed by Embrapa Agricultural Instrumentation using a parallel DSP architecture with an HEPC2E board from Hunt Engineering with two TMS320C40 processors from Texas Instruments. The software designed for visualization of bi-and(More)
This paper presents a new methodology for studying thermal behavior of grain storage bins through the use of intelligent instrumentation combined with an advanced three-dimensional (3D) interface model using computer graphic techniques, which is useful for increasing the safety margin of storage processes with consequent loss decrease. Result was obtained(More)
