We address the capture of sharp images of fast-moving objects, and build on the Motion Invariant photographic technique. The key advantage of motion invariance is that, unlike other computational photographic techniques, it does not require pre-exposure velocity estimation in order to ensure numerically stable deblurring. Its disadvantage is that the invariance is only approximate objects movin...

Image Restoration is the method of recovering original image from degraded image and also to understand the image without any artifact errors. Image restoration methods can be considered as direct and indirect techniques. Direct techniques are used when restoration results are generated in a simple one step fashion. Similarly, indirect techniques are used when restoration results are obtained a...

Synthetic transmit aperture (STA) imaging gives the possibility to acquire an image with only few emissions and is appealing for 3D ultrasound imaging. Even though the number of emissions is low, the change in position of the scatterers prohibits the coherent summations of ultrasound echoes and leads to distortions in the image. In order to develop motion compensation and/or velocity estimation...

Many conventional blind image deconvolution algorithms have much processing time because the consideration of various cases and the optimization are required for general employment. Moreover, these algorithms are also complex to deal with various point spread functions (PSF). Therefore, this paper restricts the type of PSF to the dual-exposure type and proposes effective PSF search algorithm, u...

A glycoprotein that stimulates the proliferation of multiple hemopoietic stem and progenitor cell types was purified to apparent homogeneity. The factor, termed P cell-stimulating factor (PSF), was assayed by its ability to support the growth of murine factor-dependent hemopoietic cell lines operationally termed persisting cells (P cells). PSF was purified 50,000-fold from serum-free medium con...

BACKGROUND The maximum standardized uptake value (SUVmax) is a common clinical parameter for quantification in F18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT), but it is influenced by image reconstruction. The aim of this study was to analyze the association of SUVmax deviations related to point spread function (PSF) and time-of-flight (TOF) reconstruction w...

We conduct TinyTim modeling of NICMOS camera 2 PSFs to assess limits to the accuracy of PSF subtraction imposed by color dependence, OTA focus breathing, and cold mask wiggling. The results suggest that effects of both cold mask wiggling and focus breathing can be described as a noise in a PSF-subtracted image, well above 20% of the PSF signal in narrow band filters, with a spatial scale of a f...

The present study evaluated whether the Preschool Behavior Screening System (PBSS) translated into Spanish was able to reliably provide information regarding the behaviors and emotions of preschool children. The PBSS Parent Spanish Form (PBSS-PSF) could fill a void as the first multi-stage emotional and behavioral screening system in Spanish. The PBSS-PSF was field tested on 49 Spanish-speaking...

This paper investigates the implementation of Periodic Symmetric Functions (PSF) in single electron tunneling technology. First, we discuss the procedure of expressing arithmetic and logic operations as generalized PSFs. Second, we propose a building block that performs a multiple input PSF. The block we propose can be used for the computation of any function that is or can be expressed as a PS...
