A Data Focusing method for Microwave Imaging of Extended Targets
This paper presents a data focusing method (DFM) to image extended targets using the multiple signal classification (MUSIC) algorithm. The restriction on the number of transmitter-receiver antennas in a microwave imaging system deteriorates profiling an extended target that comprises many point scatterers. Under such situation, the subspace-based linear inverse scattering methods, like the MUSI...
متن کاملA New Image Sensor with Space Variant Sampling Control on a Focal Plane
We propose a new sampling control system on image sensor. Contrary to the random access pixels, the proposed sensor is able to read out spatially variant pixels at high speed, without inputting pixel address for each access. The sampling positions can be changed dynamically by rewriting t,he sampling position memory. Since the proposed sensor has sampling position memory that stores the samplin...
متن کاملFOCAL POINT AND FOCAL K-PLANE
This paper deals with the basic notions of k-tautimmersions . These notions come from two special cases; that is, tight and taut immersions. Tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. We generalize hight and distance functions to cylindrical function and define basic notions of k-taut ...
متن کاملTo denoise or deblur: parameter optimization for imaging systems
In recent years smartphone cameras have improved a lot but they still produce very noisy images in low light conditions. This is mainly because of their small sensor size. Image quality can be improved by increasing the aperture size and/or exposure time however this make them susceptible to defocus and/or motion blurs. In this paper, we analyze the trade-off between denoising and deblurring as...
متن کاملPCA-based denoising method for division of focal plane polarimeters.
Division of focal plane (DoFP) polarimeters are composed of interlaced linear polarizers overlaid upon a focal plane array sensor. The interpolation is essential to reconstruct polarization information. However, current interpolation methods are based on the unrealistic assumption of noise-free images. Thus, it is advantageous to carry out denoising before interpolation. In this paper, we propo...
