SAR image reconstruction by expectation maximization based matching pursuit
a r t i c l e i n f o a b s t r a c t Synthetic Aperture Radar (SAR) provides high resolution images of terrain and target reflectivity. SAR systems are indispensable in many remote sensing applications. Phase errors due to uncompensated platform motion degrade resolution in reconstructed images. A multitude of autofocusing techniques has been proposed to estimate and correct phase errors in SA...
متن کاملReconstruction of Pet Image Based on Kernelized Expectation-maximization Method
Positron emission tomography (PET) image reconstruction is challenging for low count frame. The reconstruction is important method to retrieve information that has been lost in the images. To improve image quality, prior information are used. Based on kernel method, PET image intensity in each pixel is obtained from prior information and the coefficients can be estimated by the maximum likeliho...
متن کاملGeneral Convergent Expectation Maximization (em)-type Algorithms for Image Reconstruction
Obtaining high quality images is very important in many areas of applied sciences, such as medical imaging, optical microscopy, and astronomy. Image reconstruction can be considered as solving the ill-posed and inverse problem y = Ax+n, where x is the image to be reconstructed and n is the unknown noise. In this paper, we propose general robust expectation maximization (EM)-Type algorithms for ...
متن کاملAn Improved Ordered Subsets Expectation Maximization Reconstruction
Positron emission computerized tomography (PET) based on Ordered Subsets Expectation Maximization (OS-EM) is usually used to computerized tomography, which imposes the radionuclide to emission positron. But it also has some disadvantage as costing long time and bad reconstruction quality. Filtered Back Projection (FBP) that has many advantages such as simple structure and short reconstruction t...
متن کاملPreliminary evaluation of image reconstruction by ordered-subset expectation maximization in thallium-201 lung scintigraphy.
OBJECTIVES We observed whether clearer tumor delineation and greater tumor to non-tumor (T/N) count ratios could be obtained using an iterative ordered-subsets expectation maximization (OSEM) algorithm than conventional filtered-back projection algorithm (FBP) in the image reconstruction of thallium-201 (201Tl) lung scintigraphy. METHODS In 29 patients with lung cancer and phantom studies, to...
