Photorealistic Style Transfer with Screened Poisson Equation
Recent work has shown impressive success in transferring painterly style to
images. These approaches, however, fall short of photorealistic style transfer.
Even when both the input and reference images are photographs, the output still
exhibits distortions reminiscent of a painting. In this paper we propose an
approach that takes as input a stylized image and makes it more photorealistic.
It relies on the Screened Poisson Equation, maintaining the fidelity of the
stylized image while constraining the gradients to those of the original input
image. Our method is fast, simple, fully automatic and shows positive progress
in making a stylized image photorealistic. Our results exhibit finer details
and are less prone to artifacts than the state-of-the-art.Comment: presented in BMVC 201
Studies of Scintillator Tiles with SiPM Readout for Imaging Calorimeters
Imaging hadronic calorimeters with scintillator readout use small
scintillator tiles individually read out by silicon photomultipliers to achieve
the necessary granularity needed for sophisticated reconstruction algorithms at
future collider detectors. For a second generation prototype of the CALICE
analog HCAL new, 3 mm thick scintillator tiles with an embedded wavelength
shifting fiber and new photon sensor from CPTA are being fabricated. The
availability of blue-sensitive SiPMs also allows fiberless coupling of the
photon sensor to the tile, a technique requiring modified geometries to achieve
a high degree of response uniformity. We discuss results from test bench and
from test beam measurements of different scintillator tile geometries as well
as prospects for fiberless coupling of photon sensors.Comment: 5 pages, 4 figures, to appear in the proceedings of the XIV
