Data Collection Process

The dataset consists of images captured using DSLR and smartphone cameras with different exposure settings, ISO, and shutter speeds. Each image is tagged with metadata including the time of capture, camera settings, and environmental factors like street lighting, moon visibility, and weather conditions.

The dataset is divided into five categories to provide a broad range of lowlight environments:



Urban Lowlight: Captured in city streets, alleys, and building exteriors where some artificial lighting like street lamps or vehicle headlights are present.

Rural Lowlight: Taken in less-developed areas with limited to no artificial light sources, capturing natural night environments.

Indoor Lowlight: Captures images inside dimly lit rooms, homes, and spaces, including scenes lit by candles or low-wattage bulbs.

Night Sky Lowlight: Includes images of the sky at night, starry skies, moonlit nights, and various degrees of cloud cover.

Weather-Affected Lowlight: Images taken during rain, fog, or mist, further reducing visibility and introducing additional complexity for enhancement algorithms.


Key Features



Resolution & Variety: The images vary in resolution, ranging from 720p to 4K, offering flexibility for different research needs. Multiple angles and viewpoints of the same scenes are captured, ensuring diversity in each category.

Lowlight Severity: The images vary in light intensity, with some having minimal visible light sources, allowing for a more robust analysis of lowlight image processing techniques.

Noise Levels: Some images naturally exhibit high levels of noise, providing excellent training data for denoising algorithms.

Metadata-Driven: Each image includes metadata detailing the specific camera settings use, enabling researchers to understand and adjust for different photography techniques in lowlight conditions.


Dataset Organization

The dataset is organize base on the severity of lighting conditions and noise levels. Images with extremely low light and high noise are separate for advance testing of denoising and image enhancement models. Each image is provide in both RAW and JPEG formats, allowing researchers flexibility in preprocessing.

This dataset is sourced from Kaggle.

title: Supplementary Material for: Regular positive human contacts do not improve pigs’ response to a lipopolysaccharide immune challenge

description: Introduction: Little is known about the effects of a positive human-animal relationship on animal health and resilience. This study investigated the effects of regular positive human-animal interactions on pigs’ response to an immune challenge. Methods: Twenty-four female pigs were recruited at weaning (5 weeks old), and siblings of similar weights were allocated to either the positive contact treatment with positive contacts given by a human to groups of three pigs in their home pen, or to the control treatment only exposed to a human standing immobile and silently in front and outside their home pen. Treatment sessions were applied over nine consecutive weeks, lasted 10 min per group and occurred twice daily (morning and afternoon), three days a week. At 16 weeks of age, pigs were submitted to an immune challenge, which consisted of a single intravenous administration of lipopolysaccharide (LPS; 2µg/kg). The sickness behaviours of pigs were observed using scan sampling every 5 min over 6 h post-administration, recording somnolence, vomiting, diarrhoea, cramping, shivering, and panting. Blood samples were taken before the LPS administration, after 1h and 3h. Blood plasma was analysed to quantify tumour necrosis factor alpha, interleukins 6 and 10, immunoglobulin A and cortisol concentrations, and blood serum was analysed to quantify brain derived neurotrophic factor. Behavioural and physiological data were statistically analysed using general linear models in R. Results: Both treatments showed signs of sickness behaviour following LPS administration, but the two treatments did not differ in the frequency, severity of sickness behaviours or length of recovery, or in the blood plasma concentration of cytokines and cortisol measured. Conclusions: Therefore, regular exposure to positive contacts with a human over several weeks, although leading to the development of a positive human-animal relationship, did not enhance the pigs’ response to this immune challenge or the immune parameters measured in this study.

title: Supplementary Material for: Optimal Low Dose Synacthen Stimulation Test Sampling Time for Diagnosis of Adrenal Insufficiency Using Monoclonal Antibody Immunoassay

description: Context: The low-dose synacthen stimulation test (LDSST) evaluates hypothalamo-pituitary-adrenal axis function. However, studies on the correlation between morning basal and stimulated cortisol concentrations using specific monoclonal antibody immunoassays during LDSST are limited.
Objective: To determine the best time points and sampling approach for cortisol measurement using mAb immunoassay in children during LDSST.
Design and Setting: Morning basal and stimulated serum cortisol measurements in the LDSST were prospectively analysed in 132 children (61 girls) with clinical suspicion of adrenal insufficiency (AI).
Methods: Serum cortisol concentrations were assessed at 0, 30, 40, and 60th minutes during LDSST using mAb immunoassay. Simultaneously, morning basal cortisol levels in 119 patients were measured with both mAb immunoassay and liquid chromatography-mass spectrometry. Adrenal insufficiency (AI) was defined by a peak plasma cortisol concentration below 18 μg/dL (500 nmol/L).
Results: Adrenal insufficiency (AI) was excluded in 80.3% (n=106) of patients. The 40th minute showed the highest specificity (89.1%) for predicting LDSST outcomes with a single cortisol measurement. For two time-point measurements, the 40th and 60th minutes were significantly more sensitive than other possibilities (p&lt;0.001). A morning basal cortisol level below 6.5 μg/dL was identified as predictive of a failed LDSST result. 
Conclusions: In LDSST, measurement of plasma cortisol at 40th and 60th minutes reduces the risk of false positivity. Single sampling at 40th minute yielded fewer false negatives than sampling at 30th or 60th minute.

title: Supplementary Material for: Effects of light exposure duration on severity and long-term neurodevelopment following photothrombotic stroke in a neonate

description: Introduction
Perinatal stroke causes lasting neurological deficits and there are currently no effective treatment options. Established animal models of perinatal stroke do not always mimic the clinical presentation of neonatal injury or are technically challenging to perform. The photothrombotic (PT) stroke model is a minimally invasive method that replicates focal ischemic injury. Few studies have applied the PT model in neonatal contexts, and none have examined both short- and long-term effects across varying injury severities. This study aimed to optimise a protocol to create a mild model of perinatal stroke and subsequently characterize injury progression, neuropathological impact, and motor deficits over time.
Methods
On post-natal day (PND) 10 we used the PT method to induce perinatal stroke in rat pups. Pups were exposed to various light exposure times (10, 20 or 30 minutes) to determine the optimal time needed to produce a mild and reproducible cortical stroke injury. Behavioural assessments were conducted on days 4, 10, 20, and 30 post-injury. Brains were collected for analysis on days 3 and 40 post-injury. 
Results
3 days post-injury, the 20 and 30-minute group had significant focal lesions and microbleeds were present in each of the PT groups. All PT groups showed significant neuron loss in the penumbra and the thalamus, and microglia activation in multiple brain regions. As 30 minutes of light exposure showed extensive cortical tissue loss (&gt;70%), we excluded the 30-minute group from long-term assessment. 40 days post-injury, the 10 and 20-minute groups demonstrated significant tissue loss and neuronal loss in the penumbra and thalamus, but only the 20-minute group showed neuron loss in the hippocampus. The 10- and 20-minute groups both demonstrated ongoing motor deficits. 
Conclusion
Our results demonstrate that increasing light exposure time in PT stroke results in a more severe stroke phenotype. 30 minutes of light exposure resulted in a severe injury at only 3 days post insult, therefore, was not further investigated. 10 and 20 minutes of light exposure had a similar effect at 3 days, however after 40 days the 20-minute exposure time created a moderate injury phenotype. From this study we propose that 10 minutes of light exposure is optimal to create a mild stroke phenotype and is associated with motor deficits and altered neuropathology. This injury phenotype provides a focal and reproducible injury, while still being mild enough to feasibly test therapeutics.
