In all these fields, image contrast plays a crucial role. The main approach which has been applied to enhance grayscale images is the hybrid effect of histogram equalization (HE) and self-calibrated illumination method (SCIM). The main task is to apply Histogram Equalization (HE) to the ...
three laser beams (488 nm, 560 nm, and 640 nm) were used for multi-color excitation. The illumination pattern is displayed on the SLM (the same as Multi-SIM) and then filtered by an annular mask (outer NA: 0.5; inner NA: 0.375) to obtain a balanced axial and lateral resolution...

a, An imaging trilemma between quality, illumination and speed. With photon-efficient computational techniques, we can push the instrument’s capability towards lower illumination and faster imaging while maintaining a good SNR. b, A convolutional residual network with a universal noise-level estimator...
The dodecane/b-CD precipitates were dropped on the slide and observed with an optical microscope (Olympus BX51TRF with DP72- SET digital camera) equipped with polarizers in reflection mode under white-light illumination. Sample preparation. For the precipitate samples, dodecane was added into the ...
Fig. 6. (a) Multi-cycle photoresponse and (b) single-cycle photoresponse in current towards illumination of 250 nm-light, and (c) spectral responsivity and detectivity (inset) of the Ga2O3/FTO -based photodetector with the optimized 8 ± 2 SLG top electrode under 0 V bias. Responsivity ...
A trained and calibrated dentist (MW) carried out all clinical oral examinations under field conditions based on the World Health Organization (WHO) criteria [28], recording the data on a prepared record sheet. All fully erupted permanent teeth were scored, excluding third molars. Oral examinations...
signals at the different wavelengths were converted by a transimpedance amplifier (Princeton Applied Research 181) into a voltage signal measured by a lock-in amplifier (EG&G 5209). Power was measured by means of a calibrated Si-based photodiode (Newport 818-UV) and a power meter (Newport 843...
For XRD measurements, we have measured a silicon powdered sample provided by NIST (SRM 640d) and the zero point of the diffractometer was calibrated by using a peak-calibration routine implemented in the software manufactures. Microscopy Scanning electron microscopy (SEM) images were obtained using ...
There might also be some fluctuations on the display and the multispectral light source; although we carefully calibrated these. Therefore, in our study, the lowest score of 80% within the error was considered. We also focused on the color appearance mode, and there was no difference under ...
