Color Transfer Algorithm between Images Based on a Two-Stage Convolutional Neural Network.

Publication Type: Academic Journal

Source(s): Sensors (Basel, Switzerland) [Sensors (Basel)] 2022 Oct 13; Vol. 22 (20). Date of Electronic Publication: 2022 Oct 13.

Authors:

Abstract: A color transfer algorithm between images based on two-stage convolutional neural network (CNN) is proposed. The first stage network is based on VGG19 architecture as the backbone. The reference image-based color transfer (RICT) model was used to extra...

Low rank off-resonance correction for double half-echo k-space acquisitions.

Publication Type: Academic Journal

Source(s): Magnetic resonance imaging [Magn Reson Imaging] 2022 Dec; Vol. 94, pp. 43-47. Date of Electronic Publication: 2022 Sep 14.

Abstract: The present study describes a model-based approach for correcting off-resonance in the context of double half-echo k-space acquisitions. This technique employs center-out readouts in forward and reverse directions to reduce echo-times but is sensitive ...

DPSF: a Novel Dual-Parametric Sigmoid Function for Optical Coherence Tomography Image Enhancement.

Publication Type: Academic Journal

Source(s): Medical & biological engineering & computing [Med Biol Eng Comput] 2022 Apr; Vol. 60 (4), pp. 1111-1121. Date of Electronic Publication: 2022 Mar 02.

Abstract: Speckle noise reduces the image contrast significantly making the highly scattering structures boundaries difficult to distinguish. This has limited the usage of optical coherence tomography (OCT) images in clinical routine and hindered its potential b...
