This letter presents a novel synthetic aperture radar (SAR) image segmentation method based on a single graph cut. Due to the speckle, the classical pixel-by-pixel Markov random field (MRF) based SAR image segmentation method may still result in salt and pepper label map. Compared to the classical MRF based SAR image segmentation method, our proposed method exploits geometric prior to describe the...
In this paper, an improved GVF snake model that allows controllable snakes is proposed. Two kinds of extern constraint forces are exploited in the model. The first one can pin specified points on the snake and determine the basic shape of a snake. The second one avoids generating ears during curve evolution. It ensures that the curves are smooth and won't grow in a wrong direction. The improved snakes...
The new method of active fortify organizing a supervised area based on color and geometric feature is proposed in this paper. By the basis of color feature in the real supervised scene, in the first instance extracting several regions of interest (ROI) with noise, then matching with geometric shape by Fourier descriptors in the database, sequentially achieving automatic organizing a supervised area...
The technique core of grain reserves automatical supervision and audit system which based on video is to identify the grain warehouse scene video, and accurately gets the sum of grain quantity. The key to identifying the quantity is the shape of package, and the key to identifying shape is processing and describing the boundary of package. Based on a lot of research and experiment on the edge detection...
In this paper, a novel spatial and scale weighted GIST (SSWGIST) descriptor is proposed for synthetic aperture radar (SAR) image retrieval. Motivated by GIST features, images are represented by the mean values of adjacent and non-overlapped blocks of the Gabor filters response. Beyond that, our methods give those values different weights on different spatial and scale sites. The spatial weights are...
