The real-time synthesis of 3D views, facilitated by convolutional neural networks like NeX, is increasingly pivotal in various computer vision applications. These networks are trained using photographs taken from different perspectives during the training phase. However, these images may be susceptible to contamination from noise originating from the vision sensor or the surrounding environment. This research meticulously examines the impact of noise on the resulting image quality of 3D views synthesized by the NeX network. Various noise levels and scenes have been incorporated to substantiate the claim that the presence of noise significantly degrades image quality. Additionally, a new strategy is introduced to improve image quality by calculating consensus among NeX networks trained on images pre-processed with a denoising algorithm. Experimental results confirm the effectiveness of this technique, demonstrating improvements of up to 1.300 dB and 0.032 for Peak Signal Noise Ratio (PSNR) and Structural Similarity Index Measure (SSIM), respectively, under certain scenes and noise levels. Notably, the performance gains are especially significant when using synthesized images generated by NeX from noisy inputs in the consensus process.

While non-destructive in-line monitoring at manufacturing sites is essential for safe distribution cycles of pharmaceuticals, efforts are still insufficient to develop analytical systems for detailed dynamic visualisation of foreign substances and material composition in target pills. Although spectroscopies, expected towards pharma testing, have faced technical challenges in in-line setups for bulky equipment housing, this work demonstrates compact dynamic photo-monitoring systems by selectively extracting informative irradiation-wavelengths from comprehensive optical references of target pills. This work develops a non-destructive in-line dynamic inspection system for pharma agent pills with carbon nanotube (CNT) photo-thermoelectric imagers and the associated ultrabroadband sub-terahertz (THz)-infrared (IR) multi-wavelength monitoring.

Background And Objective: While whole-gland therapies for localized prostate cancer (PCa) offer excellent oncological outcomes, these can impact patients' quality of life (QoL) through serious side effects. Focal therapy using high-intensity focused ultrasound (HIFU) has emerged as a less invasive alternative to preserve QoL. However, data on the psychological impact of HIFU remain rare.

Background: Hounsfield units (HU) on computed tomography (CT) are strongly correlated with bone mineral density (BMD) and may aid in osteoporosis screening. However, there is no standardized method for assessing bone density in displaced femoral head fractures. This study aimed to measure HU values in the femoral head using preoperative post-fracture CT images of patients with intertrochanteric femoral fractures and investigate whether it correlated with BMD measured by dual-energy X-ray absorptiometry (DXA).
