A multi-focus image fusion (MFIF) framework for visual power patrol inspection is proposed in this paper. The traditional MFIF approaches based on redundant transform need lots of computation cost. In this study, the MFIF technique in dual domain is proposed. The proposed method efficiently captures detail informations of images, and reduce memory usage and computing time. The proposed MFIF method...
Since solar-induced chlorophyll fluorescence (SIF) of vegetation is closely linked to photosynthetic efficiency, it shows great potential that SIF can be exploited to monitor plant status. Since the spectrum of SIF can be used to obtain useful information like peak-ratio and spectral positions of the left and right peaks, it is valuable to retrieve the whole SIF spectrum accurately. In this study,...
Compressed sensing (CS) has been used for accelerating magnetic resonance imaging acquisitions, but its use in applications with rapid spatial phase variations is challenging, e.g., proton resonance frequency shift (PRF-shift) thermometry and velocity mapping. Previously, an iterative MRI reconstruction with separate magnitude and phase regularization was proposed for applications where magnitude...
Xilinx and Mathworks jointly proposed System Generator (SysGen) and Simulink to accelerate development of DSP (digital signal processing) style applications on Field Programmable Gate Array (FPGA) chips. However, most of developments with Simulink and SysGen end at simulation stage without complete stand-alone implementation on FPGA since these tools do not come up with sufficient IO system libraries...
In this paper, we propose a feature-based registration algorithm for the confocal fluorescence images captured by an endomicroscopy system. We first extract a number of feature points from the endomicroscopy images by applying the binarization-thinning process and using the Rutovitz crossing number. These feature points are then post-processed to eliminate the spurious ones. After that we use the...
A high spatial resolution remote sensing image provides a huge amount of data about our earth surface in more details, and makes it possible to estimate forest and tree parameters directly from aerial image. In this research the segmentation algorithm of region-merging technique was used for the identification of the individual tree crown. Fuzzy logic membership function and nearest neighbor classifier...
