Advancing artificial intelligence applicability in endoscopy through source-agnostic camera signal extraction from endoscopic images.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSuccessful application of artificial intelligence (AI) in endoscopy requires effective image processing. Yet, the plethora of sources for endoscopic images, such as different processor-endoscope combinations or capsule endoscopy devices, results in images that vastly differ in appearance. These differences hinder the generalizability of AI models in endoscopy.
methodsWe developed an AI-based method for extracting the camera signal from raw endoscopic images in a source-agnostic manner. Additionally, we created a diverse dataset of standardized endoscopic images, named Endoscopic Processor Image Collection (EPIC), from 4 different endoscopy centers. Included data were recorded using 9 different processors from 4 manufacturers with 45 endoscopes. Furthermore, images recorded with 4 capsule endoscopy devices from 2 manufacturers are included. We evaluated the camera signal extraction method using 641 manually annotated images from 5 different, publicly available endoscopic image datasets, as well as on the EPIC dataset. Results were compared it with a published baseline in terms of Intersection over Union (IoU) and Hausdorff distance (HD).
resultsIn segmenting the camera signal on images from public datasets, our method achieved mean IoU of 0.97 which was significantly higher than that of the baseline method and mean HD of 21 pixels which was significantly lower compared to the baseline. On the standardized images of the EPIC dataset, there was no significant difference between IoU but our method achieved a significantly lower HD. Both the developed AI-based method and the generated dataset are made publicly available.
conclusionThis work introduces an AI-based method that effectively segments the endoscope camera signal from the raw endoscopic data in a source-agnostic way. Utilizing the proposed method as a preprocessing step allows existing AI models to use any endoscopic image, independent of its source, without compromising performance. Additionally, EPIC, a dataset of diverse endoscopic images, is generated. The proposed method, trained AI model weights, and the EPIC dataset are made publicly available.
