In last few years, supervised deep learning has emerged as one powerful tool for image denoising, which trains a denoising network over an external dataset of noisy/clean pairs. However, the requirement on high-quality training limits broad applicability networks. Recently, there have been works that allow set noisy images only. Taking step further, this paper proposes self-supervised method only uses input itself training. proposed method, is trained with dropout pairs Bernoulli-sampled...

Blind image deconvolution (BID) is about recovering a latent with sharp details from its blurred observation generated by the convolution an unknown smoothing kernel. Recently, deep generative priors untrained neural networks (NNs) have emerged as promising learning approach for BID, benefit of being free external training samples. However, existing untrained-NN-based BID methods may suffer under-deblurring or overfitting. In this paper, we propose ensemble to better exploit NNs which...

A novel strategy for selective and sensitive amperometric detection of lead ion (Pb(2+)) was proposed based on target-induced strand release. The underlying gold electrode pre-modified with dendritic nanoparticles by direct electrodeposition to afford increased surface area immobilization thiol group-containing capture DNA molecules. hybridization the molecules Pb(2+)-specific aptamer form a duplex, into which methylene blue intercalated, induced measurable electrochemical signal.

Phase retrieval (PR) is about reconstructing a signal from the magnitude of number its complex-valued linear measurements. Recent rapid progress has been made on development neural network (NN) based methods for PR. Most these employ pre-trained NNs modeling target signals, and they require collecting large-scale datasets with ground-truth signals pre-training, which can be very challenging in many scenarios. There are few unsupervised learning employing untrained NN priors PR avoid using...

Hyperspectral image (HSI) reconstruction is about recovering a 3D HSI from its 2D snapshot measurements, to which deep models have become promising approach. However, most existing studies train on large amounts of organized data, the collection can be difficult in many applications. This paper leverages priors encoded untrained neural networks (NNs) self-supervised learning method free training datasets while adaptive statistics test sample. To induce better and prevent NN overfitting...

Exploiting temporal information of light propagation captured at ultra-fast frame rates has enabled applications such as reconstruction complex hidden geometry and vision through scattering media. However, these require high-dimensional high-resolution transport data, which introduces significant performance storage constraints. Additionally, due to different sources noise in both synthesized the signal becomes significantly degraded over time, compromising quality results. In this work, we...

Abstract Homologation of cedranediol boronic esters 1, RBO,C15H,4l with (dichloromethyl)lithium resulted in the formation (αR)-α-chloro 3, RCHCIBO2C15H24, consistently yielding (R)/(S)ratios over 25:1. The absolute configuration (R)-1-chloro-1-phenylmethylboronate 3dR was determined by X-ray diffraction. distortion five-membered 1,3,2-dioxaborolane ring from planarity found. reason why are prone to hydrolysis has been discussed.

Despite the success of pedestrian detection, there is still a significant gap in performance detection pedestrians at different scales. Detecting small-scale extremely challenging due to low resolution their convolution features which essential for downstream classifiers. To address this issue, we observed datasets and found that often gather together crowded public places. Then propose MagnifierNet, simple but effective detector towards multiple dense regions. MagnifierNet uses our proposed...

Monte Carlo methods for transient rendering have become a powerful instrument to generate reliable data in imaging applications, either benchmarking, analysis, or as source data-driven approaches. However, due the increased dimensionality of time-resolved renders, storage and bandwidth are significant limiting constraints, where single render scene can take several hundreds megabytes. In this work we propose learning-based approach that makes use deep encoder-decoder architectures learn...

The multi-object counting in visual question answering (VQA) is still a challenging problem. Existing VQA models mainly adopt object detection network to extract image features and combine soft attention mechanism further increase the model accuracy. However, repeated of same may occur when extracts features. In addition, sum weights all objects calculated by 1, which leads constant quantity information being 1. We propose new based on classification confidence. main idea calculate initial...
