Weed Identification in Maize Fields Based on Improved Swin-Unet

Weed seed loss due to predation in Michigan maize fields

The influence of weed seed predation by invertebrates and vertebrates was examined in relation to distance from hedgerows in maize fields of southwestern Michigan. Experiments were conducted in spring and winter and included five common weed species, i.e., velvet-leaf (Abutilon theophrasti), redroot pigweed (Amaranthus retroflexus), common lamb's-quarters (Chenopodium album), fall panicum (Pani...

Integrated Weed Management in Maize

Improved Invasive Weed Optimization Based on Hybrid Genetic Algorithm

An improved Invasive weed optimization (IWO) based on hybrid genetic (HGIWO) is presented. In the new arithmetic, the inertial weight is adaptively adjusted to improve the convergence speed. The weeds are multiples by the selection and hybridization of genetic arithmetic. The import of hybrid genes improves excellent performance of weeds and reduces likelihood on getting into local optimization...

The Improved DBSCAN Algorithm Study on Maize Purity Identification

In order to identify maize purity rapidly and efficiently, the image processing technology and clustering algorithm were studied and explored in depth focused on the maize seed and characteristics of the seed images. An improved DBSCAN on the basis of farthest first traversal algorithm (FFT) adapting to maize seeds purity identification was proposed in the paper. The color features parameters o...

Weed Composition in Maize (zea Mays L.) Fields under Smallholder Conservation Farming

Smallholder farmers in southern Africa have reported on increased labour requirements for hoe weeding due to high weed infestations in conservation farming (CF) fields. However, CF proponents claim that weed pressure and labour requirements for weeding decrease within the first three years under the recommended CF practices. An observational study was carried out during the 2008/09 cropping sea...
