Eos 200d

Seventy six patients will be recruited through hospital outpatient clinics, advertisements on the hospital's social media (WeChat), and leaflets displayed by community service centers. The recruitment will provide a phone number so that potential patients can contact the researchers. The dermatologist will screen patients who meet the inclusion and exclusion criteria and use a digital camera (Canon EOS 200D) to take facial photos. The study assistant will be responsible for providing study information, such as the objectives, interventions, duration, benefits, and risks. Agreed to participate in the study patients will sign informed consent. The confidentiality of information recorded by patients will be protected.

Paprika images were collected from several farms across Jeonju-si District, Jeollabuk-do, Republic of Korea, during the growing season 2019. The data acquisition was carried out using a 24.1-megapixel Canon EOS 200D-based platform with a CMOS sensor. All the images contain diverse background artifacts as well as other objects found in the field. Moreover, images captured during different time periods, under varying lightings and weather conditions, would help to make data more generalized and representative of real-field scenarios. Overall, our collected dataset has the following characteristics:
Following the above protocol, we acquired 6,000 raw images. The images were saved in JPEG format at a high resolution, to avoid being limited in available resolution at subsequent processing stages.

Desiccated R. canescens plants were taken out of silica gel for rehydration treatments and immediately transferred to glass Petri dishes (20 cm diameter) containing 100 mL of sterile deionized water. The plants were then placed in a culture room at 25 ± 1 °C, 50–60% humidity, and a photoperiod of 12 h light/12 h dark. The plants were photographed with a digital camera (EOS 200D, Canon, Japan) just before rehydration and after initiation of rehydration at 1 min, 3 min, 6 min, 15 min, 30 min, 45 min, 1 h, 3 h, 6 h, 12 h, 1 d, 3 d, and 6 d; the samples were also collected at each time point for further analysis and labeled as R0min, R1min, R3min, R6min, R15min, R30min, R45min, R1h, R3h, R6h, R12h, R1d, R3d, and R6d, respectively. Water content and relative water content (RWC) were determined for whole plants. For other analyses, the green tender parts containing stems with leaves of R. canescens gametophytes were excised from the base, frozen in liquid nitrogen, and stored at –80 °C.
