High Dynamic Range Image Hallucination

, 2008
We introduce high dynamic range image hallucination for adding high dynamic range details to the over-exposed and under-exposed regions of a low dynamic range image.

Reconstructing Interlaced High-Dynamic-Range Video Using Joint Learning

, 2017
For extending the dynamic range of video, it is a common practice to capture multiple frames sequentially with different exposures and combine them to extend the dynamic range of each video frame.

A Multiresponse Image Fusion for High Dynamic Range CMOS Image Sensor Combining Dual Conversion Gain and Logarithmic Response

IET Circuits, Devices and Systems
This article introduces a multiresponse image fusion method tailored for a high dynamic range (HDR) CMOS image sensor (CIS), which combines dual conversion gain (DCG) and logarithmic responses within a single exposure.

DNA methylation and expression of MAPRE3 affect overall survival of early‐stage non‐small cell lung cancer patients

Molecular Oncology, EarlyView.
Both cg12821679MAPRE3 methylation and MAPRE3 expression are significantly associated with overall survival (OS) of non‐small cell lung cancer. Meanwhile, MAPRE3 expression significantly modified the effect of smoking cessation on OS. Smoking cessation benefits OS merely for patients with high MAPRE3 expression.

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

Molecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

Molecular Oncology, EarlyView.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

High Dynamic Range Video Encoding Algorithm Design and Implementation

, 2007
現實生活中之可見亮度由 0cd/m2 至數千億 cd/m2 不等。以往在 影像採集設備上因為頻寬、儲存容量以及一般顯示器之顯示能力不足等因數考量下，只能以 8bit 對亮度作量化。其中在訊號轉換與量化失真所損失之資訊，在要求高傳真、高清晰度顯示設備之今天，為影像再往上提升之主要障礙。而在生醫影像、太空探勘等需要高傳真動態影像資訊之任務中，能夠進行高動態範圍影像擷取之設備，達到更少失真為該領域發展之重要因數。 可是高動態範圍影像擷取之技術，有著資料量極大，傳統方法沒辦 法相容處理和硬體設計困難等問題 ...

Patient therapy outcome modeling in cancer organoids is improved by cancer‐associated fibroblasts and organoid assembly convolution

Molecular Oncology, EarlyView.
Patient‐derived organoids (PDOs) from pancreatic, colorectal, and gastric cancers were used to evaluate standard and experimental therapies. Incorporating cancer‐associated fibroblasts (CAFs) into organoid cultures improved patient therapy outcome prediction.

A Perceptual Framework for Contrast Processing of High Dynamic Range Images

, 2006
Image processing often involves an image transformation into a domain that is better correlated with visual perception, such as the wavelet domain, image pyramids, multi-scale contrast representations, contrast in retinex algorithms, and chroma ...
