Due to the high intraclass variability and the low interclass disparity in high-resolution remote sensing (RS) image scenes, high-resolution RS scene classification is a challenging task. The performance of scene classification not only relies on discriminative feature representation but also needs appropriate classification strategies. In this paper, a scene preclassification strategy based on unsupervised...
This paper describes a system for action recognition with a single camera. Firstly, we use a two-layered background subtraction, which is based on both chromaticity and gradient, to extract human contours from the frame sequence captured by camera. This subtraction helps us remove shadows from foreground and get a good contour for recognition. Then we parameterize a human posture with a model called...
In order to establish a set of tree height measuring system, on the basis of digital image processing, this paper discusses a new method. An ordinary digital camera was used to get tree photos and two marker points were chosen in the camera's field of view on the tree. One marker point was set on the root of the tree; the other was set one meter high from the root. A tripod was used to fix the camera...
Tree image extraction is an important algorithm and technique to separate an individual tree from the surrounding landscape in a photographic image, and at the same time access the tree's feature data. In recent years, this problem is a hot issue for scientific workers in forestry research field. In order to get a better processing result to the problem, this paper makes use of image segmentation...
