Many well-known existing image matching methods are based on local texture analysis, and consequently have difficulty handling low-textured 3D objects, such as those man-made buildings and road networks in urban scenes. In this paper, we propose our urban images matching method utilizing multiple novel clues. Specifically, we explore robust image features generated by interest regions and edge groups...
This paper presents a simple image-based method of generating novel visual appearance in which a new image can be synthesized by stitching together small patches of existing images. This is a fast and very simple texture synthesis algorithm for patches of uniform size which produces surprisingly good results for a wide range of textures. Further, to improve the visual perception of synthesized texture,...
We present a novel multiresolution analysis based stereo matching method using curvelets and modified adaptive support weight. Multiresolution analysis has long been applied to stereo correspondence. However, previous methods suffer from false matches arising from textureless region or repetitive textures and fattening effect due to area based matching. In the proposed approach, we have reduced false...
A novel method is presented based on image segmentation and features point for stereo matching. Firstly, we analyse texture of the original image for distinguishing less texture and similar texture regions, as a result, we can achieve image segmentation by label image texture region. Meanwhile, we can remove smaller regions by blob filter; Then, SIFT features point and matching can achieve reliable...
It can improve the recognition rate and segmentation accuracy of moving objects in strong wind and no buildings to extract the features of trees. In this paper, the similarity criterion about the pore texture feature matching of tree crown is proposed by analyzing the pore texture feature and experimenting. The feature difference matrix of 5times5 pixels is chosen as the basic operator of tree features...
Texture synthesis has been one of the research focuses in computer graphics, computer vision and image processing fields, and it has applied in image repair, texture replacement, cartoon fracture, image coding, and error concealment. This paper introduces the study of the synthesis methods based on image blocks, presents the causal neighbor field synthesis method on based image blocks which are all...
In this paper, the importance of the tree feature recognition in the distant view is first pointed out based on the analyzing of frame and background difference method which are two practical methods in vision systems, By analyzing data and image features of distantly-viewed trees, and the matrix of 5times5 pixels is chosen as the basic operator of tree features, and the feature model and matching...
