“…This system should combine the advantages of direct and indirect laryngoscopy and achieve significant improvements in imaging quality. New technologies such as 3D imaging and 4K format must be used to achieve this goal and allow the newly developed system to be the most modern laryngeal endostroboscopy system on the market. Due to the impressive results so far, the transfer of 3D endoscopy to other medical disciplines seems to be appropriate and desirable.…”

Objective To develop a three‐dimensional (3D) laryngostroboscopic examination unit, compare the optic playback quality in relation to established 2D procedures, and report the first case series using 3D rigid laryngostroboscopy for diagnosis and management of laryngotracheal diseases. Study Design Laboratory study, prospective case series. Methods The optical efficacy of newly developed rigid 3D endoscopes was examined in a laboratory setting. Diagnostic suitability was investigated in 100 subjects (50 male, 50 female) receiving 2D high‐definition (HD) and 3D laryngostroboscopy. Two of the subjects subsequently underwent 3D‐assisted office‐based transoral phonosurgery under local anesthesia. Main outcome measures were comparative visualization of laryngotracheal pathologies, influence on preoperative planning, and evaluation of prognostic factors for the outcome of phonosurgical interventions. Results Three‐dimensional endostroboscopic procedures were effectively optimized to establish an examination protocol for all‐day clinical use. Office‐based 3D laryngostroboscopy was successfully applied in subjects with normal anatomy (n = 10) and various laryngotracheal findings (n = 90). In comparison to 2D HD videolaryngostroboscopy, the 3D view offered enhanced visualization of laryngotracheal anatomy, with qualitatively improved depth perception and spatial representation. In organic pathologies, this resulted in a more precise indication of phonosurgical procedures, increased accuracy in surgical planning, facilitated office‐based endoscopic surgery, and better evaluation of prognostic factors for the outcome of phonosurgical interventions. Conclusion Three‐dimensional laryngostroboscopy proved to increase the understanding of functional and surgical anatomy. Its application has enormous potential for improving the diagnostic value of laryngoscopy, surgical precision in laryngotracheal interventions, tissue preservation, and methods of teaching.

This review provides a comprehensive compilation, from a digital image processing point of view of the most important techniques currently developed to characterize and quantify the vibration behaviour of the vocal folds, along with a detailed description of the laryngeal image modalities currently used in the clinic. The review presents an overview of the most significant glottal-gap segmentation and facilitative playbacks techniques used in the literature for the mentioned purpose, and shows the drawbacks and challenges that still remain unsolved to develop robust vocal folds vibration function analysis tools based on digital image processing.

“…Nowadays, video surveillance systems have been widely applied in many fields to monitor emergency actions or hazardous situations [1][2][3]. In a coal mining face, the video surveillance system plays an important role in the process of coal production, which can restrict the safety and efficiency of coal mining.…”

Surveillance videos of coal mining faces have close relation to the safety of coal miners and mining efficiency. However, surveillance videos are always disturbed by some severe conditions such as atomization, low illumination, glare, and so on. Therefore, this paper proposed a hybrid algorithm (SSR-BF) based on the integration of single-scale Retinex (SSR) and bilateral filtering (BF) to enhance the image quality of surveillance videos. BF was coupled with SSR to reduce the noises and perfect the edge information in the image. The schematic diagram and pseudocode of SSR-BF was designed, and the parameters were set rationally to ensure the enhancement effects through some simulations. Finally, some comparisons with other methods were carried out, and the simulation results demonstrated that the proposed algorithm was superior to others and could be applied to image enhancement for poormonochrome images, especially the surveillance video of a coal mining face.
