Fusion of SAR image and multi-spectral (MS) image can provide complementary information about the ground observed objects. This paper presents an fusion method of SAR and multi-spectral images based on the IHS transformation and phase congruence feature extraction. The IHS transform is firstly made to MS image to separate the intensity from the hue and saturation components. Then the phase congruence...
Segmentation of unorganized point cloud is the key procedure of 3D model construction. And also the problem of management of massive point clouds can be manipulated with segmentation techniques. Global segmentation parameters and metrics are the most essential and difficulty parts of segmentation algorithm, especially in urban region. An optimization solution for segmentation of unorganized point...
Recent studies on the detection of eggshell cracks have mainly focused on the Fourier frequency analysis of a vibration-based response. This paper proposes a new detection methodology for eggshell cracks using a continuous wavelet transform and a support vector machine (SVM) technique. The proposed methodology consists of an experimental system and a data processing system. The experimental system...
In this paper, we present a new framework for blind source separation of temporal correlated signals. In general, temporal correlated signals are not independent which means the independence assumption for independent component analysis method is not satisfied. To achieve good separation performance, we apply high order statistics and temporal structure together to put the separation processing in...
