چکیده

At present, forest and fruit resource surveys are mainly based on ground surveys, the information technology of characteristic industries is evidently lagging. The automatic extraction tree from massive remote sensing data critical for healthy development industries. However, complex spatial weak spectral contained in high-resolution images make it difficult to classify trees. In recent years, fully convolutional neural networks (FCNs) have been shown perform well semantic segmentation because their end-to-end network structures. this paper, an model, Multi-Unet, was constructed. As improved version U-Net structure, structure adopted multiscale convolution kernels learn under different receptive fields. addition, “spatial-channel” attention guidance module introduced fuse low-level high-level features reduce unnecessary refine classification results. proposed model tested a pear dataset constructed through field annotation work. results show that Multi-Unet best performer among all models, with accuracy, recall, F1, kappa coefficient 88.95%, 89.57%, 89.26%, 88.74%, respectively. This study provides important practical significance sustainable industry.

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images

As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

Automatic Building Extraction from High Resolution Stereo Satellite Images

An approach was developed for automatic building extraction from high resolution stereo satellite images. The approach utilizes the spectral properties of the pan-sharpened multispectral bands and the elevation model generated from the stereo panchromatic bands. First, the pan-sharpened multispectral bands are classified using the Maximum Likelihood Classifier (MLC) to separate the buildings fr...

Automatic Road Extraction from Multispectral High Resolution Satellite Images

In this paper we propose an approach for automatic road extraction from high resolution multispectral imagery, such as IKONOS or Quickbird, in rural areas. While aerial imagery usually consists of 3 spectral bands, high resolution satellite data comprises 4 spectral bands with a better radiometric quality compared to film, but a worse geometric resolution. Therefore, strongly making use of the ...
