Zero-Reference Deep Curve Estimation for Low-Light Image Enhancement [PDF]
The paper presents a novel method, Zero-Reference Deep Curve Estimation (Zero-DCE), which formulates light enhancement as a task of image-specific curve estimation with a deep network.

CTFFIND4: Fast and accurate defocus estimation from electron micrographs
CTFFIND is a widely-used program for the estimation of objective lens defocus parameters from transmission electron micrographs. Defocus parameters are estimated by fitting a model of the microscope’s contrast transfer function (CTF) to an image’s ...

FlowNet 2.0: Evolution of Optical Flow Estimation with Deep Networks [PDF]
The FlowNet demonstrated that optical flow estimation can be cast as a learning problem. However, the state of the art with regard to the quality of the flow has still been defined by traditional methods.

Silhouettes arise in a variety of imaging scenarios. Pristine silhouettes are often degraded via blurring, detector sampling, and detector noise. We present a maximum a posteriori estimator for the restoration of parameterized facial silhouettes. Extreme dealiasing and dramatic superresolution, well beyond the diffraction limit, are demonstrated ...

Estimation of cost-effectiveness of poplar wood production in poplar plantations in Ravni Srem based on the method of pay back period [PDF]
Poplar plantations are a category of fixed assets in forestry, i.e. the assets with a biological character. They are related to their site, they are cultivated for a relatively long time and they have a relatively long utilization cycle, with the ...

Nonparametric Estimation from Incomplete Observations
In lifetesting, medical follow-up, and other fields the observation of the time of occurrence of the event of interest (called a death) may be prevented for some of the items of the sample by the previous occurrence of some other event (called a loss ...

Towards Robust Monocular Depth Estimation: Mixing Datasets for Zero-Shot Cross-Dataset Transfer [PDF]
The success of monocular depth estimation relies on large and diverse training sets. Due to the challenges associated with acquiring dense ground-truth depth across different environments at scale, a number of datasets with distinct characteristics and ...

Fast model-based estimation of ancestry in unrelated individuals.
Population stratification has long been recognized as a confounding factor in genetic association studies. Estimated ancestries, derived from multi-locus genotype data, can be used to perform a statistical correction for population stratification.
