Orthogonal moments are successfully used in the field of image analysis in the past decades. In this paper, two sets of invariants which are invariant to convolution with circularly symmetric point spread function (PSF) are introduced for object recognition and image classification using orthogonal Fourier-Mellin moments and quaternion Fourier-Mellin moments, respectively. The theoretic frameworks...
Ultrasound Current Source Density Imaging (UCSDI) potentially improves 3-D mapping of bioelectric sources in the body at high spatial resolution, which is especially important for diagnosing and guiding treatment for cardiac and neurologic disorders, including arrhythmia and epilepsy. In this study, we report 4-D imaging of a time varying electric dipole in saline. A 3-D dipole field was produced...
This paper deals with a major problem encountered in the area of airborne synthetic aperture radar (SAR) image mosaic when SAR is applied in large-scale scene. In order to enhance real-time performance and robustness of image mosaic, a mosaic method for airborne SAR image based on location is put forward. And the comparing experiments between the proposed approach and the direct image mosaic method...
Drug resistant epilepsy can in some cases be treated with surgery. To minimize potentially crippling side effects of surgery, a detailed functional map of the brain is usually required prior to resection. Conventional mapping techniques rely on a coarse grid of electrodes with limited spatial resolution. Ultrasound Current Source Density Imaging (UCSDI) is new high resolution method to image electric...
Mobile handheld device, as small screen, limited user interface and hardware power, can not browse web pages designed for PCs comfortably. By means of mobile web 2.0, a new mobile web presentation with better user experience is proposed. A thumbnail view of the original web page is firstly presented to mobile user. While mobile user browsing the thumbnail view page, moving his mouse pointer, the original...
The objective of this study is to investigate the feasibility of imaging colon cancers using multi-modal optical imaging system combining optical coherence tomography (OCT) and fluorescence molecular imaging (FMI). This system enables simultaneous imaging of tissue morphology and molecular information at high resolution (10-20 mum) over a 3-5 mm field-of-view. OCT reveals the microstructures of normal...
